Common Drugs used on Star Trek

The hypospray is loaded with several common drugs. Here is a cross-section, along with their major efficacies.

CORDRAZINE– A powerful stimulant. Useful for waking unconscious patients, or as a general stimulant to keep patients awake. To be given in SMALL doses only, as overdose can cause cardiac problems or cause Dr. McCoy to go off the deep end and leap into Time Guardian portals.

NETINALINE– A less powerful stimulant used to revive unconscious patients. This substance should not be used while operating heavy machinery, or playing professional sports, as it WILL show up in a steroid/HGH test.

DEXALIN– Used to treat patients suffering from oxygen deprivation. This is a replacement for the older tri-ox compound, which I still keep around in case a crewman drinks too many Pan-Galactic Gargle Blasters at Quark’s.

HYRONALIN– Synthetic drug used to treat radiation sickness in humanoids, also given as an immunization prior to exposure to radiation. Replaced adrenaline which was used prior to its discovery. NOTE: DO NOT administer this drug to “Furries”, as it can result in severe allergic reactions. Use ADRENALIN instead.

STERILITE– Anti-infective agent used during surgery and in the general treatment of wounds to produce rapid death of harmful microorganisms and parasitic agents.

ANESTHEZINE– Anesthizine was a fast-acting anesthetic, administered through environmental systems as a gas. It was considered among “the best,” along with axonol and neurozine, during the late 24th century. (VOY: “Message in a Bottle”) A concentration of seventy parts per million was typically enough to put a humanoid to sleep. (TNG: “The Hunted”)

Other popular drugs, Amelioratives, and medicines


Adrenaline (C9H13O3N), also known as epinephrine, is a Human hormone and neurotransmitter with powerful effects on the sympathetic nervous system. As a drug, it is used to treat radiation poisoning. Although by 2267 it had been replaced in clinical use by hyronalin, adrenaline was found to be effective in the treatment of an unknown radiation left over by particles originating from a comet that passed near Gamma Hydra IV. The radiation had caused an hyperacceleration of the aging process. (TOS: “The Deadly Years”)

During the USS Enterprise’s 2267 visit to Gamma Hydra IV to check up on its colonists, it was discovered that they had all died of hyperaccelerated aging. Ensign Pavel Chekov discovered a dead body and it had startled him, causing adrenaline to be released into his system. The adrenaline protected him from the radiation sickness. Doctor Leonard McCoy figured out the adrenaline connection and synthesized an adrenaline hypo shot for the rest of the infected crew. (TOS: “The Deadly Years”)

On stardate 1512.2, navigator Bailey mentioned to Spock that his raising of his voice did not indicate that he was scared, but that he just had a human thing called “an adrenaline gland”. Spock remarked that it was most inconvenient and suggested that he have his removed. (TOS: “The Corbomite Maneuver”)

ADTH is a stimulant which can be dispersed through a starship’s life support systems.

In 2367, Lieutenant Commander Data put five parts per million of ADTH into the airflow of the USS Enterprise-D to wake the crew after they had been stunned by the Paxans’ fake wormhole. (TNG: “Clues”)

Alcohol (chemical designation ethyl alcohol or ethanol) is a colorless, liquid chemical, usually the by-product of fermenting sugar. Alcohol is a powerful psychoactive drug with intoxicating effects in humanoids.

Alcohol is often replaced by synthehol, which carries all the properties of alcohol, but without the deleterious effects. When mixed with a theragen derivative, it blocks certain nerve impulses to the brain and can be used to treat the “madness” caused by exposure to interphase. (TOS: “The Tholian Web”)

In 2374, an unnamed lifeform, having newly stolen Tom Paris’ form, replicated five alcoholic beverages in USS Voyager’s mess hall and became thoroughly intoxicated. (VOY: “Vis à Vis”)

Jean-Luc Picard confiscated an alcoholic liquid called Dresci from Captain Dirgo while marooned on Lambda Paz. He observed that while the alcohol would advance dehydration if consumed, it could be useful as a coolant or disinfectant. (TNG: “Final Mission”)

Alizine is a medicine used to counter an allergic reaction in Klingons. This was one of the facts Kathryn Janeway remembered from her Academy course on Klingon Physiology. (VOY: “Darkling”)

Alkysine is a drug used to lessen the damage to neurological tissue after a catastrophic injury. It is not always effective for all injuries and on all species.

Dr. Beverly Crusher tried using an alkysine treatment on Lieutenant Worf following his spinal cord injury in 2368, but the medication was unsuccessful. (TNG: “Ethics”)

Alpha-wave inducer
An alpha-wave inducer is a substance or device used as a sleep aid. It functions by easing the introduction of alpha waves into the brain. It is only meant for occasional use.

Ty Kajada used an alpha-wave inducer while on Deep Space 9 when she had trouble sleeping. (DS9: “The Passenger”)

Ambizine was an injectable drug used as a sedative.

In 2376, Tom Paris used ambizine to sedate Dala while other crewmembers of the USS Voyager executed a plan to find out where her crew had hidden their loot. (VOY: “Live Fast and Prosper”)

An analeptic (or analeptic compound) is a drug that counteracts the effects of radiation.
In 2373, Neelix took some analeptic compounds with him on a mission to a Nezu colony planet being bombarded by asteroids. (VOY: “Rise”)

The Malon use analeptic compounds to ameliorate the cellular degradation caused by theta radiation exposure. In 2375, Fesek treated B’Elanna Torres with analeptic compounds during a mission to prevent a malfunctioning Malon freighter from exploding. (VOY: “Juggernaut”)

When the USS Voyager was split into different timeframes in 2377 by a chrono-kinetic surge, Tom Paris ordered that analeptics be given to crew members suffering from radiation poisoning once the netrazine ran out. (VOY: “Shattered”)

An analgesic was a drug used to relieve pain without inducing a loss of consciousness. Analgesics were often used to treat headaches and to relieve pain induced by mild bruising to severe injury. (VOY: “Critical Care”, “Tsunkatse”, ENT: “Observer Effect”)

When ordered to create a diversion to slow down a Borg invasion of the USS Enterprise-E, the EMH in the Enterprise’s sickbay offered the intruding Borg drones an analgesic skin cream to combat skin irritation caused by their implants. (Star Trek: First Contact)

The Doctor begrudgingly gave B’Elanna Torres an analgesic when she complained of a bad headache in 2373.(VOY: “The Swarm”)

Anesthesia is the complete or partial loss of sensation induced by anesthetic drugs. Anesthetic drugs were strong sedative drugs used to numb a patient’s sensation to pain to induce a deep sleep immediately prior to medical treatment, such as surgery. Anesthetics could be applied in varying degrees and forms depending on the patient’s health and requirement of the medical procedure.

Anesthetics were typically administered intravenously into the patient’s bloodstream with a hypospray or syringe. (VOY: “Critical Care”) Anesthetics also existed in gaseous form and could be administered on a large scale through a ship’s ventilation system. An example of the last occurred when The Doctor and the USS Prometheus’ EMH Mark II released Neurozine gas to incapacitate Romulan Tal Shiar agents who had stolen the vessel. (VOY: “Message in a Bottle”)

Anesthetic agents included:

Anesthesia gas
Hyvroxilated quint-ethyl metacetamin
Nasal numbing agent
Neurazine gas

Anesthesia gas
Anesthesia gas was an anesthetic drug available – in gaseous form – on Constitution-class vessels in the 23rd century.

In 2267, Commander Spock and Captain James T. Kirk flooded almost all decks on the USS Enterprise with anesthesia gas to retake the ship from Khan Noonien Singh and his group of Augments. (TOS: “Space Seed”)

Anesthizine was a fast-acting anesthetic, administered through environmental systems as a gas. It was considered among “the best,” along with axonol and neurozine, during the late 24th century. (VOY: “Message in a Bottle”) A concentration of seventy parts per million was typically enough to put a humanoid to sleep. (TNG: “The Hunted”)

Anetrizine was an anesthetic medication.

In 2374, The Doctor used twenty ccs of anetrizine to anesthetize Seven of Nine’s cranial nerves. (VOY: “The Gift”)

Animazine is a stimulant used to keep a person awake.

In 2374, The Doctor recommended giving large doses of animazine to the crew of the USS Voyager to keep them awake. He gave Commander Chakotay an animazine derivative to use to stay awake, but Chakotay instead used it on a member of the dream species who were affecting the Voyager crew. (VOY: “Waking Moments”)

Anjoran bio-mimetic gel
Anjoran bio-mimetic gel was a type of bio-mimetic gel that was valued as a commodity.

In 2370, Commander Riker offered Captain Yog one half gram of Anjoran bio-mimetic gel for five hundred kilograms of magnesite ore. (TNG: “Firstborn”)

It is not stated if “Anjoran” is a species, or a certain type of bio-mimetic gel. It is likely a specific way of producing it, as bio-mimetic gel was strictly policed by the Federation, who were the only ones capable to producing it. (DS9: “Distant Voices”, “In the Pale Moonlight”)

An antacid is a form of medication that helps alleviate acute functional dyspepsia (heartburn).

When Neelix made up Rodeo Red’s Red-Hot, Rootin’-Tootin’ Chili, several crewmembers received heartburn, thus requiring Tom Paris to replicate an antacid for them. (VOY: “Message in a Bottle”)

An anti-intoxicant is a medicine that allows one to drink alcohol without experiencing the effects of intoxication. In 2153, Doctor Phlox gave Captain Archer an anti-intoxicant so that he could withstand the effects of the Andorian ale which he was drinking with Degra, in an attempt to get Degra to give up information on the Xindi superweapon. (ENT: “Stratagem”)

Benjamin Sisko and his infiltration team treated themselves with anti-intoxicants before attending the induction festivities for the Order of the Bat’leth, a celebration where copious amounts of Klingon bloodwine are traditionally consumed. Without the drug, Worf claimed that they would have been so drunk they wouldn’t have been able to stand. (DS9: “Apocalypse Rising”)

A antibiotic is a chemotherapeutic drug used to inhibit or abolish microorganisms, such as bacteria, fungi, or protozoa.

In late 2000, Shannon O’Donnell called the nonexistence of antibiotics one downside of the classical age, but Henry Janeway replied that this had caused families to care for each other. (VOY: “11:59”)

In early 2375, Doctor Julian Bashir was to give Quark an antibiotic for an ear infection. (DS9: “Afterimage”)

An anticoagulant is a substance that delays or prevents the clotting of blood.

Jem’Hadar disruptors incorporate an anticoagulant into the energy stream; this prevents wounds inflicted by the weapon from healing. (DS9: “The Ship”, “Change of Heart”)

Aphrodisiac refers to a number of compounds that produce heightened sexual desire and awareness in some humanoid species.

According to William T. Riker, an aphrodisiac is “something used to stimulate or enhance sexual pleasure”. Data was not familiar with the term. (TNG: “Angel One”)

Humans have, at various times, used aphrodisiacs including the ground horn of a rhinoceros. (ENT: “Fight or Flight”)

Certain cultures consider perfume an aphrodisiac. (TNG: “Angel One”)

In 2373, Quark attempted to smuggle the illegal aphrodisiac Regalian liquid crystal onto Deep Space 9. (DS9: “The Ship”)

Arithrazine was a medication used for the most extreme cases of theta radiation poisoning. According to Starfleet Medical protocols, a doctor has to monitor the patient who has received arithrazine during treatment.

When the USS Voyager encountered the Omega molecule in the Delta Quadrant, Captain Janeway intended to go out and destroy the molecule after receiving arithrazine by The Doctor. As he could not monitor her, he initially refused to give the medication, but she overruled him with the Omega Directive. The arithrazine was later used to inoculate rescue team members on a mission to destroy the Omega molecules. (VOY: “The Omega Directive”)

Asinolyathin is an analgesic pain medicine. It is used specifically for muscle spasms. (DS9: “Visionary”)

Axonol was a medicine that could be dispersed in gaseous form, as a crowd-control anesthetic, by the Federation and Starfleet.

On the USS Prometheus, it was one of three agents recommended for use at the behest of the Emergency Medical Hologram Mark II, the other two being anesthezine and neurozine. (VOY: “Message in a Bottle”)

An antigen is a substance or molecule that elicits an immune response. Antigens are frequently peptides or carbohydrates derived either from the host (“self-antigens” or “autoantigens”) or from pathogens such as bacteria or viruses. Antigens are presented on the surface of cells by specialized protein complexes in a manner that elicits either an antibody response or a cytotoxic effector cell response.

Doctor Julian Bashir administered an antigen to several Teplan patients in late 2372, hoping it would help cure the Teplan blight. Although it was later determined injecting patients with antigens would not cure them of the Dominion-created disease, the antigen was able to allow the children of the Teplans to be immune, as the antigen was absorbed by the placenta, and could prevent them from developing the blight. (DS9: “The Quickening”)

In 2373, The Doctor created a synthetic antigen to treat the macrovirus outbreak on USS Voyager. Although the original plan was to release the antigen via the ship’s environmental systems, when the Tak Tak attacked Voyager to prevent the spread of the virus, causing damage to the ship’s power systems, Captain Janeway had to improvise, creating a holodeck simulation to lure the virus into one place. With the virus contained in one area, Janeway threw an antigen bomb into the holodeck, destroying the virus. (VOY: “Macrocosm”)


Benjisisrinde was a cardiovascular drug used to treat Vulcans who suffered from congestive heart failure.

This drug was prescribed for Sarek, Spock’s father, who suffered from congestive heart failure; however, his condition became too advanced for medical therapy alone, and surgery was required. (TOS: “Journey to Babel”)

Benzethonium chloride
In 2151, following a rock climbing accident on Risa, Ensign Travis Mayweather was given bezethonium chloride at a Risan hospital. He turned out to be highly allergic to it, and suffered from swelling that threatened to constrict his airway. (ENT: “Two Days and Two Nights”)

Benzocyatizine is type of medication used to treat low serum isoboramine levels in Trill patients.

In 2371, Jadzia Dax’s isoboramine level began to decline when the Dax symbiont experienced flashbacks of a previous host, Joran Belar, as a result of the failure of a memory block. To compensate (and in an attempt to hide the truth regarding Trill symbionts), Doctor Renhol put Jadzia Dax on a regimen of benzocyatizine. This treatment, however, did not work. (DS9: “Equilibrium”)

Bicaridine is an analgesic medication often used as a substitute for metorapan.

In 2368, Wesley Crusher was treated with bicaridine instead of metorapan because he was allergic to metorapan. (TNG: “The First Duty”)

Bio-mimetic gel
Bio-mimetic gel was a liquid substance used in the study of genetics that was highly regulated as contraband by Federation law. Its sale was forbidden, and it could be hazardous if not transported correctly. (DS9: “Distant Voices”) Its applications included the creation of biogenic weapons and organic explosives, as well as illegal genetic and cloning experiments. (DS9: “In the Pale Moonlight”) Even attempting to obtain the substance was a felony in the Federation. (DS9: “Distant Voices”)

Due to its restricted nature, bio-mimetic gel was rare and valuable. In 2370, the USS Fleming was carrying this substance through the Hekaras Corridor when it was disabled. In the initial stages of the investigation by the USS Enterprise-D, Dr. Crusher hypothesized that the Fleming may have been hijacked for its cargo. (TNG: “Force of Nature”)

That same year, Ro Laren lied to the Maquis, telling them that a Ferengi transport came to the Demilitarized Zone to deliver bio-mimetic gel. She also claimed the substance was legal. (TNG: “Preemptive Strike”)

Borathium was a new rybotherapy developed by Doctor Toby Russell in 2368. She believed it to be decades more advanced than two related medications, leporazine and morathial, although it was still in the experimental stages at the time.

She used the drug on a seriously-injured survivor of the USS Denver disaster in 2368, although morathial may have been effective. The survivor later died from neural metaphasic shock, but Russell was content with the fact that she gained valuable data which would allow her to improve borathium. She felt she was justified in sacrificing one patient to potentially save thousands in the future. Dr. Beverly Crusher was not happy with Dr. Russell’s decision, and relieved her of medical duty aboard the USS Enterprise-D following the incident. (TNG: “Ethics”)


The removal of caffeine from beverages has plagued bartenders and restauranteurs for centuries! You can’t expect me to solve it overnight!” – Quark (DS9: “Nor the Battle to the Strong”)
Caffeine (C8H10N4O2) is a stimulant present in a variety of foods and beverages, including coffee and raktajino. It can be somewhat addictive to most humanoids (excluding Vulcans) if consumed on a regular basis. For centuries bartenders and manufacturers have tried unsuccessfully to create a suitable substitute.

According to Charles Tucker, Zariphean tea had enough caffeine in it to keep a Human awake for three days straight. (ENT: “Breaking the Ice”)

As of the 24th century, there was yet to be a decaffeinated raktajino with a decent taste. Quark’s attempt to create such a beverage for Major Kira during her pregnancy with Miles and Keiko O’Brien’s son failed miserably. Had he succeeded, the new concoction would have been called “Quarktajino”. (DS9: “Nor the Battle to the Strong”)

Cateline is a drug that can cause a simulated anaphylactic shock. It was used by The Doctor to render B’Elanna Torres unconscious as she had discovered a malfunction of his program. (VOY: “Darkling”)

Cervaline was a drug that was used to fend off rejection of transplanted organs or tissue.

In order for Denara Pel’s Vidiian brain to accept the graft of Klingon neural tissue, The Doctor determined that she had to receive 500 milligrams of cervaline every four hours. (VOY: “Lifesigns”)

Chloraxine is a chemical substance which is lethal in a sufficient dosage.

In 2151, the Starfleet crew of the prototype NX-class starship Enterprise discovered an Axanar vessel. At least one member of the Axanar crew was killed by a lethal dosage of chloraxine. (ENT: “Fight or Flight”)

Chloromydride is a strong cardiostimulant, generally used when inaprovaline is ineffective.

When Worf began to go into cardiac arrest following surgery involving the genitronic replicator in 2368, Dr. Beverly Crusher ordered him to be injected with fifteen ccs of chloromydride. (TNG: “Ethics”)

Chronexaline was a drug under development at Starfleet Medical in the year 2404, designed to protect biomatter from tachyon radiation.

In that year, Admiral Kathryn Janeway requested 2,000 milligrams from The Doctor, in order to protect her from the harmful side effects of the chronodeflector, a time travel-device which she subsequently used to travel to 2378 and change history, returning the USS Voyager to Earth sixteen years earlier than it would have without the admiral’s intervention. (VOY: “Endgame”)

A coenzyme is a biological molecule that facilitates enzymatic actions. They can be used to slow the progress of chromovirus.

On the Dinaali Hospital Ship 4-2 in 2377, Doctor Voje informed The Doctor that Tebbis’ chromoviral infection had worsened rapidly because his coenzyme allottment had been reduced, due to his low treatment coefficient. (VOY: “Critical Care”)

Colgonite astringent
Colgonite astringent is a cosmetic application reputed to be particularly intense.

Beverly Crusher treated herself to the treatment in 2367 during a romantic interlude with Odan. (TNG: “The Host”)

Contraception injection
The contraception injection was a form of birth control used in the Federation. The medicine had to be administered regularly, otherwise sexual intercourse could lead to fertilization and pregnancy.

During negotiations with the Gideon, Captain Kirk proposed that the Federation could provide any type of devices they needed to safely prevent conception. (TOS: “The Mark of Gideon”)

In 2375, Benjamin Sisko, preoccupied by the latter stages of the Dominion War, forgot to renew his injection, despite repeated reminders from his CMO, Julian Bashir. As a result, his wife, Kasidy Yates, became pregnant with their child, the couple’s first. (DS9: “The Dogs of War”)

Cordafin is a drug that can be used as a stimulant.

In 2374, Tim Watters took cordafin stimulants for two months while in command of the USS Valiant. (DS9: “Valiant”)

Cordrazine was a strong chemical stimulant useful for emergency medical treatment. It was primarily used to stimulate the heart during cardiac arrest. The drug was a red liquid and was injected with a hypospray. In 2267, Captain Kirk noted that cordrazine was “tricky stuff,” (TOS: “The City on the Edge of Forever”) but by the 24th century, it had become ubiquitous and was being used by physicians in much higher doses than in Kirk’s day. (TNG; DS9; VOY)

History Edit
Hikaru Sulu upon treatment with cordrazine
Hikaru Sulu, suffering from heart flutter after being shocked by the bridge console while passing through a time displacement, was revived by a few drops of cordrazine. Dr. Leonard McCoy then suffered an extreme overdose when he accidentally injected an excessive amount of the chemical into his body. (TOS: “The City on the Edge of Forever”)

Dr. McCoy also used one cc of cordrazine to revive Rizzo to consciousness. (TOS: “Obsession”)

A more potent form of cordrazine, called tricordrazine, is commonly used in resuscitation in the 24th century. Dr. Beverly Crusher attempted to use tricordrazine to revive Worf after he went into heart failure, following a risky surgery using the genitronic replicator to repair his damaged spinal column. (TNG: “Ethics”)

In 2369, Dr. Crusher told her staff to prepare a cordrazine series for Jean-Luc Picard after his artificial heart was damaged and the captain was failing fast. (TNG: “Tapestry”)

In 2371, Bareil Antos was given two ccs of cordrazine by Julian Bashir and Jabara. Bashir himself was given four ccs of cordrazine several weeks later, after being placed in a coma following Altovar’s attack. (DS9: “Life Support”, “Distant Voices”)

The Doctor used two ccs of cordrazine to revive Harry Kim after he was killed by a Vhnori cenotaph. (VOY: “Emanations”)

On “Planet Hell” in 2372, Neelix suggested that Tom Paris administer cordrazine to an ailing repto-humanoid infant. (VOY: “Parturition”)

Bashir gave cordrazine to several Teplans in 2372, hoping to alleviate the pain caused by the Dominion’s Teplan blight. Epran and Ekoria were among those given the drug, although the former had stopped responding to it before he died. Bashir was concerned that the high level of the drug he’d administered to Ekoria might be hard on her baby’s metabolism. (DS9: “The Quickening”)

The Doctor used fifty milligrams of cordrazine to stabilize Tuvok in 2373 when a gaseous anomaly unearthed repressed memories in Tuvok. (VOY: “Flashback”)

Corophizine was an antibiotic drug that was usually used to prevent secondary infections.

Doctor Julian Bashir gave Chief Miles O’Brien thirty cc’s of corophizine to lower his fever when he suffered from the aphasia virus but it was unsuccessful. (DS9: “Babel”)

Cortical analeptic
A cortical analeptic was a type of drug administered via hypospray, used to reinvigorate tissue in the cerebral cortex.

The Doctor had Kes prepare several doses of the drug while he prepared to perform motor cortex reconstruction surgery on Tom Paris in 2373. (VOY: “The Swarm”)

Cortical suppressant
A cortical suppressant is a drug that inhibits certain types of activity in the humanoid brain.

In 2376, The Doctor administered a cortical suppressant to Abaddon to protect him from the sentient starship Alice, who had caused him to suffer a cerebral hemorrhage through her neurogenic interface. (VOY: “Alice”)

Cortolin was a drug that was helpful in resuscitating patients who had stopped breathing.

In 2370, Doctor Julian Bashir administered 10 ccs of cortolin to Quark after the latter had been wounded by a compressed tetryon beam weapon. (DS9: “Necessary Evil”)

Cortropine was a stimulant included in standard-issue Starfleet medkits.

Dr. McCoy utilized cortropine to overcome symptoms of weakness experienced by the landing party on Taurus II. (TAS: “The Lorelei Signal”)

CPK enzymatic therapy
CPK enzymatic therapy is a medical treatment used to limit the extent of neurological damage after a catastrophic injury. The therapy is not completely effective for all injuries or all species, such as Klingons.

Dr. Beverly Crusher tried CPK enzymatic therapy on Lieutenant Worf following his spinal cord injury in 2368, but his condition did not improve. (TNG: “Ethics”)

Crytobiolin was a chemical that was used by the Angosians during the Tarsian War to enhance their soldiers’ abilities in battle.

Known soldiers who were given the drug include Roga Danar. (TNG: “The Hunted”)

Cytogenics are a type of drug.

The con artist Gar once sold a supply of cytogenics to Administrator Chellick of the Dinaali Hospital Ship 4-2, though they were useless due to expired expired lots and diluted samples. Thus, Chellick was disinterested when Gar offered him another supply in 2377. (VOY: “Critical Care”)

Cytoglobin was a drug that was used to treat chromoviral infections and arterial aging.

In the 24th century, cytoglobin was in short supply on the Dinaali homeworld. In 2377, the Allocator of Hospital Ship 4-2 was prioritizing cytoglobin to prevent arterial aging in high-TC patients on Level Blue, while denying it to low-TC chromoviral patients on Level Red. Daily injections with the substance increased life expectancy up to 40%.

The Doctor, who had been stolen and sold to the Dinaali by Gar, found this situation appalling, as cytoglobin that could have been used to save lives were instead being used on preventative treatments.

At first, The Doctor attempted to smuggle cytoglobin from Level Blue to Level Red. However, after his friend Tebbis died from chromovirus, he resorted to infecting the hospital administrator, Chellick, with chromovirus in order to force him to divert cytoglobin from Level Blue. (VOY: “Critical Care”)

Cytokinetic injection
A cytokinetic injection was a drug that enhances cellular activity.

In 2375, The Doctor used a cytokinetic injection to trigger a genetic reversion in the corpse of “David Gentry”, causing the body to change back into its original form of a Species 8472. (VOY: “In the Flesh”)



Dalaphaline was a systemic stimulant drug.

In 2270, Doctor Chapel used five ccs to strengthen Spock after his mind meld with V’Ger, which had caused him some neurological trauma. (Star Trek: The Motion Picture)

Delactovine was a systemic stimulant drug.

In 2368, Doctor Crusher tried to use delactovine to keep Captain Picard alive when his connection to the Kataan probe was severed. However, no medical method could stabilize Picard’s condition, so the USS Enterprise-D crew had to allow the probe’s beam to reconnect with the captain again. (TNG: “The Inner Light”)

Dermal osmotic sealant
Dermal osmotic sealant is a medication used to protect humanoids from high levels of trigemic vapors. (VOY: “Parturition”)

Dermaline was an injectable drug used to prevent sunburns.

In 2376, Neelix was so excited to be on a beautiful Norcadian beach that he forgot to take his dermaline injection and ended up getting severe burns. (VOY: “Tsunkatse”)

Dermaline gel
Dermaline gel is made from dermaline and used as a treatment for first and second degree burns, such as those in injuries caused by a ruptured nitrogen line.

Doctor Phlox used dermaline gel to treat an engineer who received first degree burns when a nitrogen valve seal blew in 2151. (ENT: “Dear Doctor”)

In 2372, Kes was told by The Doctor to treat a crewman’s second degree burns with dermaline gel. (VOY: “Deadlock”)

Dermatiraelian plastiscine
Dermatiraelian plasticine was a dermal regenerative agent used to maintain skin resilience after large-scale cosmetic surgery.

The fact that Aamin Marritza had taken large doses of the compound was part of the evidence that he had been surgically altered to resemble Gul Darhe’el in order to come to Bajor and expiate Darhe’el’s crimes. (DS9: “Duet”)

Desegranine was a Cardassian drug used to reverse memory loss.

The drug was used by the Obsidian Order during the 24th century to help its undercover agents remember their true identities. When used, memories began to resurface within a few hours.

Corbin Entek administered a dosage of desegranine to Kira Nerys in 2371, in a failed attempt to revive the non-existent memories of Iliana Ghemor. (DS9: “Second Skin”)

Dexalin is used in the treatment of oxygen deprivation.

In 2368, Dr. Beverly Crusher treated two J’naii survivors from the shuttlecraft Taris Murn for oxygen deprivation with dexalin. (TNG: “The Outcast”)

Dylamadon is a sedative that can simulate death in an individual.

In 2369, Counselor Deanna Troi was given dylamadon in order to trick Ves Alkar into breaking his detrimental psychological link with her. (TNG: “Man of the People”)

Dylovene is a broad-spectrum antitoxin carried in 2260s Starfleet medkits.

On stardate 5554.4, Dr. McCoy used dylovene in an attempt to treat Sulu when he was poisoned by a retlaw plant. (TAS: “The Infinite Vulcan”)


Elasian tears
Elasian tears, secreted by Elasian females, contained a biochemical compound transmittable to Elasian (and Human) males. Upon skin contact, men became romantically infatuated and somewhat enthralled to the woman who infected them.

Men of Elas tried for centuries to dispel the tears’ “mystical powers” without success. Troyian Ambassador Petri said of the phenomenon, “A man whose flesh is once touched by the tears of a woman of Elas has his heart enslaved forever.”

In 2268, Captain James T. Kirk was infected by the tears of Elaan, the Dohlman of Elas. Although he was visibly affected and drawn to Elaan, he managed to overcome the tears’ more compelling effects in a short time – just as Dr. Leonard McCoy believed a cure was within reach as they acted like an infection. First Officer Spock speculated that the USS Enterprise was all the antidote Kirk needed for Elasian tears. (TOS: “Elaan of Troyius”)


Felicium originated as a vaccine for a plague that existed on Brekka’s neighboring planet, Ornara. The vaccine was supplied by the Brekkians in exchange for goods. Even after the plague was over the Ornarans had unknowingly become addicted to the vaccine, the terrible withdrawal symptoms leading them to think they were still affected by the disease, and Brekka continued to produce it for them in a profitable business. As years passed the Brekkians refined the drug to make it more and more potent.

The euphoria seemed to be somewhat sedative and pain relieving, similar to planet Earth’s opiates. (TNG: “Symbiosis”)

Felodesine chip
The felodesine chip was a small poison tablet used by members of the Romulan military to commit suicide. It was usually formed into a small, one-inch orange disk. There was no antidote known to the Federation.

Alidar Jarok committed suicide by ingesting a felodesine chip in 2366. (TNG: “The Defector”)

Formazine is a stimulant, acting through the lymphatic system on the central nervous system. Normally used to promote alertness and reduce fatigue, in higher doses it can cause severe restlessness and irritability. (TOS: “By Any Other Name”)


Glucagon is a naturally-occurring hormone in Humans. Administered as a drug, glucagon is used to treat hypoglycemia or beta-blocker overdose. Glucagon causes glycogenolysis, a breakdown of glycogen stored in the liver into glucose.

In 2024, Doctor Bashir tried to get Lee some GlucaGen (a trade name brand of glucagon widely available in the 20th and 21st century). (DS9: “Past Tense, Part II”)


Hexatriol was a medication used to treat serious plasma burns.

In 2152, E’lis, a medic at a deuterium mining camp, took a package of hexatriol from the Enterprise NX-01’s sickbay, as part of an agreement between the miners and the Enterprise crew. (ENT: “Marauders”)

Hydrocortilene was an analgesic medication used during the 24th century to alleviate pain, specifically headaches.

In 2373, The Doctor used a hypospray with 3% hydrocortilene to treat Lieutenant B’Elanna Torres’s headache. (VOY: “The Swarm”)

Hyperzine was a standard stimulant.

In 2370, Dr. Julian Bashir administered two twenty-cc doses of hyperzine to Elim Garak to counter the seizures caused by his cranial implant. (DS9: “The Wire”)

Hyronalin was a medicinal drug used to counter the effects of radiation poisoning. Adrenaline was the preferred treatment shortly after Earth’s atomic age, but hyronalin replaced it after its discovery. (TOS: “The Deadly Years”)

In 2367, hyronalin was used to protect the crew of the USS Enterprise-D from radiation poisoning when a three-hundred-year-old garbage scow was discovered. Doctor Crusher and her staff mass-replicated the drug and prepared to coordinate with Gamelan V’s physicians in the administration of it. These actions were taken in response to projected radiation levels that would mostly have affected a trio of islands on the planet. (TNG: “Final Mission”)

The following year, Crusher and La Forge required a few days of hyronalin treatment after exposure to plasma fire radiation. (TNG: “Disaster”)

In 2371, Doctor Julian Bashir used hyronalin to treat Chief Miles O’Brien’s radiation poisoning. (DS9: “Visionary”)

In 2373, The Doctor inoculated Tom Paris temporarily against radiation poisoning from an astral eddy with a combination of hyronalin and lectrazine. (VOY: “Real Life”)

Hyvroxilated quint-ethyl metacetamin
Hyvroxilated quint-ethyl metacetamin was an anesthetic.

When consumed in quantities of seventeen milligrams in about a half-liter of water (approximately 30 to 40 parts per million), it would render a Human barely able to stand.

In 2370, Quark tried to fix a racquetball match between Julian Bashir and Miles O’Brien by attempting to drug the doctor with a herbal beverage consisting of water, sucrose, dextrose, general root extract, grain particulates, yeast, synthehol and the substance. Bashir was unamused. (DS9: “Rivals”)


Immunosuppressants are a type of drug used to limit the response of the immune system in humanoids.

To help William T. Riker’s body to accept the Odan symbiont, Dr. Beverly Crusher administered an immunosuppressant to combat the symptoms of Riker’s body rejecting the symbiont. (TNG: “The Host”)

Impedrezene was a narcotic that impeded one’s ability by slowing down the higher brain cell functions. The drug could last for hours in Humans. It attacked neuro-cognitive motor function by suppressing higher cognitive abilities. Extreme headaches were associated with use of this drug after the effects had worn off. (VOY: “Alliances”, “Investigations”)

Improvoline was a standard sedative in 2373.

At one point in that year, The Doctor attempted to give Lon Suder five ccs of improvoline to calm Suder down, but Suder refused. (VOY: “Basics, Part II”)

Inaprovaline was a synaptic stimulant and cardiostimulant. It worked by fortifying the cell membranes and could be used as a preventative measure or in response to various physical illness. Chloromydride was a stronger version of inaprovaline.

In 2151, while exploring an uncharted M-class planet, several of the crew of Enterprise became affected by tropolisine. Doctor Phlox discovered that inaprovaline, combined with being removed from the pollen-saturated environment, would allow the delusional effects of tropolisine to dissipate. (ENT: “Strange New World”)

Also in 2151, while the crew of the Vahklas was aboard the Enterprise, T’Pol went to bed without meditating. Her dreams were unsettling and she was agitated upon awaking, so she asked Doctor Phlox for 25 milligrams of inaprovaline to calm her nerves. (ENT: “Fusion”)

In 2366, the Zalkonian “John Doe” crash-landed on a planet and was rescued by the USS Enterprise-D. Suffering from low autonomic responses, Dr. Beverly Crusher gave “John Doe” sixty ccs of inaprovaline. (TNG: “Transfigurations”)

When Worf began to lose brain function following his surgery involving the genitronic replicator in 2368, Dr. Beverly Crusher injected him with forty ccs of inaprovaline and then seventy-five ccs more. The drug did not have an effect, forcing her to try chloromydride. (TNG: “Ethics”)

When Jean-Luc Picard was injured by a Lenarian at a diplomatic conference in 2369, Dr. Crusher injected him with forty ccs of inaprovaline. (TNG: “Tapestry”)

Infra-sensory drugs
Infra-sensory drugs were specialized therapeutic chemical compounds utilized in the treatment of psychiatric disorders.

In 2266, the USS Enterprise delivered a shipment of infra-sensory drugs to Doctor Tristan Adams, director of the Tantalus V penal colony. (TOS: “Dagger of the Mind”)

Inpedrezine is a drug.

In 2371, a representation of Benjamin Sisko Julian Bashir encountered in his mind following a Lethean telepathic attack told a nurse to give a patient inpedrezine. (DS9: “Distant Voices”)

Intraspinal inhibitor
An intraspinal inhibitor was a drug which induced paralysis by inhibiting the signals in the spinal cord.

In 2373, The Doctor injected Lieutenant Torres with an intraspinal inhibiting drug after he malfunctioned when attempting to enhance his personality subroutines. (VOY: “Darkling”)

Invernian herb
Invernian herb is a medicinal herb located in remote areas of Invernia II.

In 2351, a young Julian Bashir and his father witnessed the death of a native Ivernian girl who, unknown to them, could have been saved by the Ivernian herb. This incident led Julian Bashir to a career in medicine. (DS9: “Melora”)

Ipecac is a purple-tinted drug in liquid form which, when ingested, causes severe gastric distress in Humans. Ipacac is easy to conceal, and appears to dissolve very quickly in room-temperature liquids.

Ipecac was used by Doctor Julian Bashir to poison a drink in a holosuite program in Quark’s on Deep Space 9, part of an elaborate ruse staged by station personnel to defeat a jack-in-the-box subroutine planted in the “Vic’s lounge” holoprogram by its creator, Felix. (DS9: “Badda-Bing, Badda-Bang”)

In present-day medicine, ipecac (often called “syrup of ipecac”) is used as a purgative, to induce vomiting.

Isoboramine (also spelled as isoboromine) is a neurotransmitter in Trill physiology which regulated the connections between the host and the symbiont. Low isoboramine levels were harmful and could be fatal to the host and/or symbiont, so if isoboramine levels dropped below 40%, then the symbiont was removed. This would kill the host, but any joined Trill would willingly sacrifice themselves in order to save their symbiont.

Official records at the Trill Symbiosis Commission stated that in 2285, when Torias Dax was in a shuttle accident, he was placed in a coma. He was left in a vegetative state until his isoboramine levels eventually fell below 40% and the symbiont had to be removed. In actuality, the symbiont had been transferred to Joran Belar.

In 2371, Jadzia Dax’s isoboramine levels fell dangerously low when a chemical memory blocker was wearing off in the Dax symbiont. (DS9: “Equilibrium”)

Isomorphic injection
An isomorphic injection was a drug used by Species 8472 during their operation to infiltrate Starfleet in 2375. The injections maintained the genetic alterations that allowed them to masquerade as Alpha Quadrant species. (VOY: “In the Flesh”)


Katyllian clove
The Katyllian clove was a plant from the Delta Quadrant that was used as an herb.

A Talaxian theta radiation remedy called for crushed Rama leaf and Katyllian cloves, though the mixture also triggered a gag reflex. Neelix made some in 2375 while preparing to board a disabled Malon freighter. (VOY: “Juggernaut”)

Kayolane is a sedative which causes unconsciousness for several hours.

In 2367, Dr. Beverly Crusher gave Susanna Leijten a hypospray of ten ccs of kayolane after her blood chemistry was altered by alien retro-DNA and she began to exhibit strange behavior. (TNG: “Identity Crisis”)

Kelotane is a drug used to treat burns.

In 2371, Seska received a three cc dose of kelotane after being burned aboard a Kazon starship. (VOY: “State of Flux”)

Ketracel-white (or simply white) is an addictive narcotic containing an isogenic enzyme and nutrients. One of the active ingredients of white is yridium bicantizine. The Jem’Hadar soldiers of the Dominion were genetically engineered to lack the enzyme which white provides, and require frequent doses of the drug to survive. The white also provided all the nutrients they required, alleviating them of the need to eat or drink.

Without white, Jem’Hadar soldiers suffered withdrawal symptoms including pain, anxiety, loss of mental control, and inability to “shroud”; eventually the Jem’Hadar spiral into homicidal insanity. First killing their enemies followed by their allies, they would inevitably turn on each other. Ultimately, their entire genetic structure would collapse. (DS9: “Rocks and Shoals”) On rare occasions, a Jem’Hadar was born with a genetic mutation which allowed their bodies to produce the white they needed, though most such instances went unnoticed. (DS9: “Hippocratic Oath”) All attempts to remove this genetically engineered addiction have thus far failed.

The addiction to white ensured the Jem’Hadars’ loyalty to the Founders. However, for most Jem’Hadar this was unnecessary, as their loyalty was already absolute. Distribution of the white was controlled by the Vorta, and was dispensed to the Jem’Hadar First in a formal ceremony:
Vorta: “First [name], can you vouch for the loyalty of your men?” Jem’Hadar: “We pledge our loyalty to the Founders, from now until death.” Vorta: “Then receive this reward from the Founders, may it keep you strong.”
Jem’Hadar bred in the Alpha Quadrant occasionally dispensed with the formal ceremony claiming that their loyalty was shown by their actions rather than their words. (DS9: “One Little Ship”). In the event of the death of the Vorta or the detachment of a group of Jem’Hadar from their main unit, the Jem’Hadar First can unlock the white case. (DS9: “Rocks and Shoals”, “One Little Ship”, “To the Death”)

Kironide is a very rare and long-lasting source of great power.

In 2268, the Starship Enterprise arrived at the planet known as Platonius, where the inhabitants had gained extraordinary psychokinetic powers, which they used to entertain themselves by sadistically torturing Alexander, a Platonian who did not have the powers. It was discovered that they had gained their powers due to the kironide that was present in the local vegetation, and that Alexander did not have the powers because he posessed a pituitary deficiency which prevented him from metabolizing the kironide. In order to escape the control of the Platonians, Doctor McCoy injected Captain Kirk and Commander Spock with a high dose of kironide in order to reproduce the Platonians’ powers. Their plan worked and they were soon able to overpower Parmen, the Platonian leader, and gain their and Alexander’s freedom. (TOS: “Plato’s Stepchildren”)


Lectrazine was used to stabilize the cardiovascular and renal systems of humanoids. It could also be combined with hyronalin for temporary protection against radiation poisoning.

In 2371, The Doctor administered twenty milligrams of lectrazine to Tuvok after the Vulcan began having convulsions in main engineering. (VOY: “Fury”)

The following year, The Doctor administered twenty milligrams of lectrazine to the Vidiian doctor Denara Pel in order to stabilize her cardiovascular and renal systems. (VOY: “Lifesigns”)

In 2373, The Doctor gave Kes lectrazine to counteract the disruptions in her cardiac functions. (VOY: “Sacred Ground”) Kes attempted to give Tieran twenty milligrams of lectrazine in order to save his life, but Tieran’s biochemistry was incompatible with the medication. (VOY: “Warlord”) The Doctor gave Lieutenant Tom Paris a combination of lectrazine and hyronalin to temporarily protect him from radiation poisoning. (VOY: “Real Life”)

In 2374, The Doctor gave twenty milligrams of lectrazine to a member of the bridge crew when she was in hypertensive shock. (VOY: “Scientific Method”)

In the script of DS9: “To the Death”, Julian Bashir has a nurse use lectrazine to treat a woman who suffered a spinal fracture and trauma to the cranial meninges in the Jem’Hadar attack on Deep Space 9. The dialogue cannot be heard clearly in the episode. [1]

Leola ointment
Leola ointment is a Talaxian homeopathic treatment for sunburn, made from leola root.

Neelix made some leola ointment for himself after he fell asleep on a beach on Norcadia Prime during shore leave in 2376. He later found out that he was allergic to leola ointment, necessitating intervention by The Doctor. (VOY: “Tsunkatse”)

Leporazine is a resuscitative drug used only in extreme cases because of its strength. (TNG: “Ethics”)

Lexorin was a drug utilized during the late 23rd century that was developed to alleviate symptoms of malaise and/or multiple personality disorder in those who experienced a Vulcan mind meld, or who carried a Vulcan katra prior to its placement on Mount Seleya.

James T. Kirk administered a dose of lexorin to Leonard McCoy to help him feel well enough to travel with Spock’s katra to Vulcan. (Star Trek III: The Search for Spock)

Love philtre
A love philtre is a magic potion used by the Megans to attract lovers. Since all the women of Megas-Tu are as young and beautiful as they want to be, they need an edge to ensnare the man they desire. (TAS: “The Magicks of Megas-Tu”)

Love potion crystal
Love potion crystals were an item Harry Mudd conned “a crazy old Sirius medicine man” out of while on the planet Sirius IX in 2269; the medicine man whom he so conned would not specify their actual origins. He, in turn, sold the crystals to several thousand of the planet’s inhabitants, who experienced adverse effects from them.

Escaping subsequent charges on Sirius, Mudd escaped to Motherlode, where he attempted to sell his remaining love crystals to the miners for three hundred credits per crystal. There he was found by Spock of the USS Enterprise, and was taken into custody aboard the starship. On the Enterprise, Mudd talked Head Nurse Christine Chapel into taking a crystal from him to use on Spock. He also broke several crystals near an air system grille to aid in his escape aboard the shuttlecraft NCC-1701⁄12.

The crystals worked by breaking the crystal and applying the liquid within to one’s skin, and then touching another person. Rubbing the liquid potion on the skin could cause temporary dizziness. To Harry Mudd’s own surprise, the crystals actually had a temporary effect on the Enterprise crew. Spock fell briefly in love with Nurse Chapel, while the crew of the Enterprise herself became intoxicated by the love potion fumes through the air ducts.

Less fortunately for Mudd’s possible hopes of an honest pursuit of interstellar commerce, the potion had a rebound effect once its main effect wore off; that meant the crystals would be a poor buy at even half-price.(TAS: “Mudd’s Passion”)

D-lysergic acid diethylamide (C20H25ON3), commonly called LSD, is a powerful psychotropic drug that was used for medical, spiritual, and recreational purposes on Earth.

While visiting Earth in 1986, James T. Kirk attempted to explain Spock’s erratic behavior to Gillian Taylor by saying that he believed Spock had used too much LSD (mistakenly referring to it as “LDS”) during the 1960s while “he was part of the Free Speech Movement at Berkeley”, California. (Star Trek IV: The Voyage Home)


Macrospentol is one of the drugs used by the Angosians to enhance their soldiers during the Tarsian War. (TNG: “The Hunted”)

Mahko root
The mahko root is a plant native to the planet Neural. It is the only known cure for the poisonous bite of the deadly Mugato, and then only when properly administered by a female shaman of Neural’s Hill People known as the Kahn-ut-tu. The treatment is highly ritualized.

The ritual involves the beating of drums and chanting of certain incantations as the shaman creates a wound in her own hand, takes hold of the mahko root against the wound, then presses it against the victim’s wound. The root then seems to move of its own power as it draws the toxin out. It may act as a filter between the two circulatory systems to help screen out the poison. It is unknown if the ritual itself has anything to do with the healing processes, but the root certainly has an effect of cleansing the body.

Incidentally, the ritual also acts as a pseudo-marriage ceremony between the victim and the administering Kahn-ut-tu shaman, as the victim now owes the shaman his or her life. (TOS: “A Private Little War”)

Makara herb
The makara herb is a native plant of Bajor, a herb known for its medicinal value. It is typically used in Bajoran women to increase their progesterone during pregnancy. It is also known to act as a counter agent to various sedatives, including merfadon. (DS9: “The Darkness and the Light”)

Doctor Julian Bashir prescribed makara herbs for Major Kira Nerys during her pregnancy in 2372 and 2373, to help with swollen ankles while she was carrying Miles and Keiko O’Brien’s baby. She likened the taste to “something that crawled out of Quark’s ear.” (DS9: “Body Parts”)

In 2373, Furel and Lupaza brought Kira fresh makara herbs, picked the previous night on Bajor. (DS9: “The Darkness and the Light”)

Maraji crystal
A Maraji crystal is a controlled addictive substance illegal in the Cardassian Union. According to Quark, Cardassians didn’t like the crystals (or possibly their effects) and Bajorans were too poor to buy them.

In 2366, a spy for the Romulans, named Livara, was reportedly peddling maraji crystals on Terok Nor. Odo was investigating Livara’s actions, and discovered that Livara had tried to sell the crystals to Quark.

In a hallucination experienced by Deep Space 9 personnel in 2373, a distorted view of this event was presented, where the inquiry about Livara’s maraji smuggling was made by Thrax, rather than Odo. (DS9: “Things Past”)

Mars Toothpaste
Mars Toothpaste was a variety of dental hygiene product used on planet 892-IV.

In 2268, Captain James T. Kirk noted an advertisement for Mars Toothpaste in an issue of The Gallian during his visit there. According to one of the planet’s inhabitants, Septimus, the name of this toothpaste was “taken from the names of false gods.” (TOS: “Bread and Circuses”)

Masiform D
Masiform D was a powerful stimulant that could administered via a hypospray.

When Commander Spock was once poisoned by thorns fired from a pod plant on Gamma Trianguli VI in 2267, Doctor McCoy quickly gave him enough Masiform D to “make the whole crew turn handsprings,” in response to the attack, but it got no immediate reaction.

A short time later, Spock came to, as a result of the Masiform D injection, stating, “Dr. McCoy’s potion is acting like all his potions; turning my stomach. Other than that, I am quite well.” McCoy ribbed back, blaming Spock’s physiology on his reaction of the drug, “If your blood were red instead of green, you wouldn’t have an upset stomach.” (TOS: “The Apple”)

Melenex is an anesthetic that was carried in 2260s Starfleet medkits.

In 2269, Doctor McCoy used melenex to make Spock appear ill, fooling the computer that controlled the Shore Leave Planet. McCoy described the effects of melenex as “brief unconsciousness and temporary skin discoloration,” adding, “It looks worse than it is.”

Once the doctor dosed Spock with ten ccs of melenex via hypospray, McCoy told Spock that it would take ten seconds to take effect, resulting in unconsciousness for less than five minutes. (TAS: “Once Upon a Planet”)

In the novelization of “Once Upon a Planet” (as published in Star Trek Log 3), a drug called corpelomine replaces melenex and is said to take approximately twenty seconds to take effect, rather than the exact ten seconds.

Melorazine was a standard sedative.

In 2369, Nurse Ogawa administered a dose of twenty ccs to Deanna Troi in order to stop her struggles while she was being treated in a biobed. (TNG: “Man of the People”)

Merfadon is a type of sedative.

In 2373, Silaran Prin used merfadon to sedate Kira Nerys with the intention of removing the unborn Kirayoshi O’Brien, so that no innocents would die when he murdered her for disfiguring him. However, the makara herbs Kira took for her pregnancy counteracted the drug, allowing her to deceive and subdue Prin. (DS9: “The Darkness and the Light”)

Methohexital (C14H18N2O3) was a sedative barbiturate substance which was primarily used in hospitals and other medical facilities. It was often used in tandem with anesthesia to induce a deep sedation.

In 2004, Loomis stole some methohexital from a blood bank at which he worked to sedate his victims, whom he was delivering to the Xindi-Reptilians for whom he was working. (ENT: “Carpenter Street”)

The box of methohexital seen on “Carpenter Street” was mistakenly labeled “mexhohexital.”

Metorapan is an analgesic medication, which can be substituted with bicaridine.

In 2368, Wesley Crusher was treated with bicaridine instead of metorapan because he was allergic to it. (TNG: “The First Duty”)

Metrazene was a drug used to treat cardiac arrhythmias.

In 2367, Dr. Crusher asked Nurse Ogawa for two hundred milligrams of the drug when William T. Riker was having the Odan symbiont implanted. (TNG: “The Host”)

Mirazine is a drug used in the 22nd century that reduced the time necessary for decompression when boarding and leaving a starship.

In 2151, Doctor Phlox gave Commander Trip Tucker 40 milligrams of mirazine to cut in half the normal six-hour decompression time. (ENT: “Unexpected”)

Mood enhancer
“Mood enhancer” was a general name Taymon gave for a kind of drug used on Taresia. It was injected subdermally by Taresian females into the necks of their male partners. Taymon claimed that they were “mild” and had “no side effects”. He encouraged Harry Kim to allow the injection but Kim refused. (VOY: “Favorite Son”)

Similar to leporazine, morathial a drug used to treat medical patients who suffered cardiac arrest. It was considered safer than borathium, since it was less likely to cause neural metaphasic shock.

Toby Russell used borathium on a seriously-injured survivor of the USS Denver disaster in 2368, although morathial may have been effective. The survivor later died from neural metaphasic shock, but Russell was content with the fact that she gained valuable data which would allow her to improve borathium. She felt she was justified in sacrificing one patient to potentially save thousands in the future. Dr. Beverly Crusher was not happy with Dr. Russell’s decision, and relieved her of medical duty aboard the USS Enterprise-D following the incident. (TNG: “Ethics”)

Morathial series
A morathial series is a group of resuscitative drugs used for one-shot dosing in simple resuscitations. (TNG: “Ethics”)

Morphenolog is an analgesic drug.

In 2371, Dr. Julian Bashir gave Vedek Bareil a two cc dose of morphenolog to ease the pain being caused by damage to his left parietal lobe due to ongoing treatments with vasokin. (DS9: “Life Support”)

Myofibrilin was a growth hormone prescribed for extended zero gravity missions. The invention of artificial gravity caused myofibrilin to fall out of use by 2155, except for during certain military exercises, and for workers in remote places where artificial gravity was impractical, such as mining colonies.

In 2155, Doctor Phlox discovered traces of myofibrilin in the blood of Susan Khouri, a nurse who had been murdered by Terra Prime, the xenophobic group to which she once belonged. With this information, the crew of the Enterprise NX-01 was able to deduce that Terra Prime was based out of the Orpheus Mining Colony on the moon. (ENT: “Demons”)


Nasal numbing agent
A nasal numbing agent was an injection to reduce the perception of odors. Subcommander T’Pol took injections to reduce the smell Humans produce. (ENT: “The Andorian Incident”)

Neodextramine solution
After Harry Kim was forced to return to the USS Voyager from Banea in 2371, he suffered from dehydration in his shuttle. Upon returning, he was given a neodextramine solution. (VOY: “Ex Post Facto”)

Neoethylene was a type of drug compound used in 23rd century Federation medicine.

When the USS Enterprise was overrun with appeared to be “giant tribbles” in 2269, Doctor Leonard McCoy was able to remedy the situation by giving them “a simple shot” of neoethylene. As a result, the “giant tribbles”, which were in reality tribble colonies with voracious appetites, broke down into their individual units with a slower metabolic rate. (TAS: “More Tribbles, More Troubles”)

In chemistry, the term “neo” refers to a new chemical compound that is isomeric with a related compound. While neoethylene is a fictitious compound, based on the nomenclature, it could theoretically be described as having the same number of atoms as ethylene (C2H4), but have a different structural arrangement and properties.

Netinaline is a stimulant used to resuscitate a patient.

In 2371, a two cc dose was administered to the Vhnori Ptera to revive her. (VOY: “Emanations”)

Netrazine was a treatment for radiation poisoning.

In 2377, Tom Paris instructed another crewmember on its application, telling her to switch to analeptics once her supply was consumed. (VOY: “Shattered”)

Neural blocker
A neural blocker is a drug that inhibits certain nervous system functions, suppressing pain and motor control.

On the Dinaali Hospital Ship 4-2 in 2377, The Doctor inquired why Tebbis was not given a neural blocker for his pain. Doctor Voje informed him that Tebbis, who had a low treatment coefficient, had already received his allottment. The Doctor later injected the hospital administrator, Chellick, with a neural blocker combined with chromovirus, to force him to divert enough cytoglobin to save all the chromoviral patients in the hospital. (VOY: “Critical Care”)

Neural paralyzer
A Neural paralyzer is a central nervous system depressant, standard in Starfleet medkits circa 2260. Used in surgery as a preanesthetic, it acts within 5-10 minutes and lasts for about 15-20 minutes to depress cardiac and respiratory functions, incidentally making the subject nearly appear dead. (TOS: “Amok Time”)

There may be many such available drugs of this type, one of which might be melenex.

Neural suppressant
A neural suppressant is a drug that inhibits certain types of activity in the nervous system.

In 2376, The Doctor administered neural suppressant to several members of the USS Voyager crew, to block the traumatic memories of the Nakan massacre caused by the neurogenic pulse of the Tarakis memorial monument. (VOY: “Memorial”)

Later that year, The Doctor injected Kathryn Janeway, Tuvok, and B’Elanna Torres with neural suppressant as part of a plan to infiltrate a Borg tactical cube. The suppressant allowed them to be assimilated by the Borg without losing their individuality, though it began wearing off after a time. The suppressant also impaired the integration of Borg implants, allowing The Doctor to remove most of them from their bodies after the mission. (VOY: “Unimatrix Zero, Part II”)

A neuro-sedative was a drug designed to keep a patient sedated.

When abducting crewmembers of the USS Enterprise-D, a species of solanogen-based lifeforms injected them with a strong neuro-sedative so they would be unconscious when entering their realm through a spatial rupture and wouldn’t remember the experiments that were conducted on them.

The neuro-sedative left behind large amounts of serotonin in the abductees’ hippocampus and visual cortex, arousing the suspicion of Doctor Beverly Crusher. She devised a neuro-stimulant that would counteract the effects of the sedative so that the aliens could be stopped by the crew of the Enterprise. (TNG: “Schisms”)

A neuro-stimulant was a drug administered to keep a patient from falling asleep.

Doctor Beverly Crusher injected Commander William T. Riker with a neuro-stimulant to counteract the neuro-sedative given to him by solanogen-based lifeforms whenever they abducted him into their realm. The stimulant would keep him awake when entering their realm through a spatial rupture. It was given to him before being taken for the final time by the aliens. The Doctor had to inject him with a very high dosage, as the alien sedative was very strong and warned him that the procedure might be risky. In this case the drug did work to keep him awake without any major side effects. (TNG: “Schisms”)

In ENT: “Bound”, Phlox used what he simply called “Stimulants” to stay awake. It seems possible that these were also Neuro-stimulants.

Neurozine is an anesthetic that was used during the late 24th century that can be dispensed in gaseous form. In 2374, neurozine, axonol and anesthezine were considered to be “only the best.”

That year, The Doctor and EMH Mark II used three canisters of neurozine gas, distributed through the ventilation system, to incapacitate the Romulans who had hijacked the USS Prometheus. (VOY: “Message in a Bottle”)

Niaxilin was a drug that could be used to separate two Denobulans during their mating period when they became too aggressive.

In 2151, Doctor Phlox explained its use to his friend Doctor Jeremy Lucas when the latter was serving on Denobula. (ENT: “Dear Doctor”)

Nogatch hemlock
Nogatch hemlock is a substance which is extremely poisonous to humanoids. It has no known antidote.

In 2372, Q gave Quinn Nogatch hemlock so that he could commit suicide. USS Voyager’s Doctor stated that the drug was not available in the ship’s medical stores, and Lieutenant Tuvok stated that the ship’s replicators would not produce it either. (VOY: “Death Wish”)

Norepinephrine (abbreviated norep) or noradrenaline is a hormone and neurotransmitter in the humanoid central nervous system. As a stress hormone, it affects the part of the brain that controls alertness as well as the fight-or-flight response. Along with epinephrine or adrenaline, it increases heart rate and blood pressure, thus increasing blood flow to muscles in addition to triggering the release of glucose from the body’s energy stores. (TNG: “Skin of Evil”, “Who Watches The Watchers”)

In 2372, The Doctor found elevated levels of norepinephrine in Lon Suder, which suggested increased aggressive tendencies. However, he also noted that Suder’s levels were not significantly different from any of the other former Maquis crew. (VOY: “Meld”)

The Clown, a manifestation of fear in Viorsa’s virtual reality stasis system, metaphorically chopped his victims’ heads off by raising the amount of norepinephrine in their bodies to such extreme levels that they suffered massive heart attacks and died. (VOY: “The Thaw”)

Numanol capsule
Numanol capsule was a medication used in the sickbay of the USS Enterprise in 2268. (TOS: “Day of the Dove”)

Its purpose is unknown.

Nytoxinol is a drug that causes tissue transplant rejection.

In 2372, Denara Pel, temporarily existing as a hologram, injected her real body with nytoxinol, causing her brain to reject the Klingon neural tissue that had been grafted to her cerebral cortex. Pel did this because she did not wish to return to her diseased body, even if it meant she would only live a few more days before her synaptic pattern degraded within the holobuffer. (VOY: “Lifesigns”)


A painkiller is a medicine that eases one’s pain.

Doctor Beverly Crusher gave Jean-Luc Picard a painkiller when he was experiencing an unknown form of pain when DaiMon Bok returned his previous command starship, the USS Stargazer. (TNG: “The Battle”)

In 2372, Doctor Julian Bashir gave Norva a painkiller. However, it had no effect as she was experiencing the final stages of the Teplan blight. (DS9: “The Quickening”)

After Jadzia Dax was injured by a Jem’Hadar weapon on Soukara, Worf gave her painkillers, although the anticoagulant from the Dominion weapon meant she needed to take more. (DS9: “Change of Heart”)

Peridaxon is a drug used to treat Irumodic syndrome, a degenerative neurological disorder which causes progressive deterioration of the synaptic pathways. Peridaxon is simply palliative, as there is no known cure for the syndrome. (TNG: “All Good Things…”)

A placebo is a substance containing no medication which is given to reinforce a patient’s expectation to get well or, alternatively, used in medical experiments as a control measure.

In 2153, Dr. Phlox gave Commander Tucker a placebo after he wouldn’t try Vulcan neuropressure therapy. (ENT: “The Xindi”)

Every flu season on the USS Voyager, Neelix became convinced that he had Toluncan ague. Rather than arguing with him, The Doctor would simply give him a placebo. (VOY: “Virtuoso”)

Polyadrenaline is a synthetic version of the hormone epinephrine, also known as adrenaline. It is designed as a stimulant which can aid in the revival of a patient who has died or is near death.

Dr. Beverly Crusher used twenty-five cc polyadrenaline to assist Worf’s Klingon physiology in reviving his systems after his entire spinal column was replaced by the genitronic replicator in 2368. (TNG: “Ethics”)

Polynutrient solution
Polynutrient solution is a parenteral nutrition formula given to patients suffering from malnutrition.

Dr. Bashir prepared an IV drip of polynutrient solution for Odo after his runabout crashed on a class L planet. (DS9: “The Ascent”)

Priaxate was a drug used in 2151 by Doctor Phlox to alleviate the most severe symptoms of the plague afflicting the Valakians. He also instructed the Valakians in how to synthesize the drug. (ENT: “Dear Doctor”)

Promazine was a clear round pill developed by the Obsidian Order for use by their operatives in case of capture. The pill not only kills a person swiftly and painlessly but turns them into dust within hours, leaving nothing left for identification.

Dukat tried to use promazine to kill his followers on Empok Nor in 2375. (DS9: “Covenant”)

Psychoactive drug
A Psychoactive drug is a mood-altering chemical substance. It primarily affects the central nervous system by altering brain function resulting in changes in behavior, perception, consciousness, and cognition. Psychoactive drugs induce elation and euphoria, hallucinations, or altered sensory experiences.

While psychoactive drugs are can be used for recreational purposes, such as a narcotic, some cultures use psychoactive drugs in the form of herbs for use during spiritual quests or rituals.

Chakotay revealed to Kathryn Janeway that in the past, Native Americans used psychotropic herbs while embarking on vision quests to induce an altered state of consciousness. With the advent of modern technology, however, they moved away from using drugs to induce hallucinations and instead discovered the akoonah, a device that affects one’s mind just like the herbs. (VOY: “The Cloud”)

One example of a powerful psychoactive drug is the semi-synthetic drug LSD.

Psychotropic drug
A psychotropic drug is a chemical that alters brain function in such a way as to affect mood, consciousness, perception, or behavior. These effects are usually temporary.

During the 1960s, some Humans on Earth used a psychotropic drug known as LSD for recreation, which caused some damage to their minds later in life. James T. Kirk, during a time travel mission that visited Earth’s past, used this fact in an attempt to explain Spock’s unusual comments, behavior, and attire, by stating that he had taken too much of the drug during that era while partaking in the Free Speech Movement at Berkeley, California. (Star Trek IV: The Voyage Home)

In 2151 an away team from the Enterprise NX-01 fell victim to a naturally occurring psychotropic compound, known as tropolisine on an uninhabited Class M planet. (ENT: “Strange New World”)

The Ktarian game was stimulating the brain similar to a psychotropic drug. (TNG: “The Game”)

Empok Nor had been the site of a failed experiment by the Cardassians to use psychotropic drugs to enhance Cardassian xenophobia, in order to create more effective soldiers. Three members of the First Order, Third Battalion were treated to the drug, and left behind in stasis tubes when the station was abandoned. The two surviving members were awakened in 2373 by a Starfleet salvage team, who killed three members of the team before being killed by Elim Garak, who had also been exposed to the drug. The drug caused Garak to kill a fourth member of the team before he was neutralized by Chief Miles O’Brien. (DS9: “Empok Nor”)

Pulmozine was a drug used to treat oxygen deprivation and stimulate breathing.

In 2372, The Doctor gave 40 milligrams of pulmozine to one of Seska’s aides, Tierna, after he was brought aboard the USS Voyager. (VOY: “Basics, Part I”)

In 2373, The Doctor used pulmozine to stimulate breathing in Lieutenant B’Elanna Torres after she was injured during an attack on the Nasari. (VOY: “Favorite Son”)


Quadroline is an emergency resuscitative drug used on Malcor III to treat cardiac arrhythmias. (TNG: “First Contact”)


Radiogenic vaccine
Radiogenic vaccines are a class of medications designed to protect an individual against radiation exposure.

In 2377, the hologram of Reginald Barclay, after being reprogrammed by DaiMon Nunk, provided the crew of the USS Voyager with inoculations that would supposedly protect them against geodesic radiation. The Doctor, however, noticed that they were similar to standard Federation radiogenic vaccines, and would not be sufficient. (VOY: “Inside Man”)

Rama leaf
Rama leaf is a part of a plant from the Delta Quadrant, used as an herb.

A Talaxian theta radiation remedy calls for crushed Rama leaf and Katyllian cloves, though the mixture also triggers a gag reflex. Neelix made some in 2375 while preparing to board a disabled Malon freighter. (VOY: “Juggernaut”)

Regalian liquid crystal
Regalian liquid crystal was an illegal, highly dangerous and sometimes intoxicating aphrodisiac.

In 2373 Quark attempted to import Regalian liquid crystal with a shipment of Regalian fleaspiders that Doctor Bashir had asked him for. (DS9: “The Ship”)

Rejuvenation drug
Rejuvenation drugs were a class of drugs intended to extend ones life span. Rao Vantika, a Kobliad scientist, was known to have experimented with such drugs. (DS9: “The Passenger”)

While not specifically referred to as such, the de-aging treatment from Cerberus II and the treatment Matthew Dougherty hoped to develop based on Metaphasic radiation might also count as Rejuvenation drugs.

Retinax V
Retinax V was a medication usually prescribed as a treatment for people with presbyopia in the 23rd century. Some people, such as James T. Kirk, were allergic to this form of medication, and the alternative of “reading glasses” was therefore still required. (Star Trek II: The Wrath of Khan)

Rhuludian crystal
Rhuludian crystals were a form of narcotic chemical commonly sought out in the Delta Quadrant.

In 2373, they were offered for sale to Chakotay and Tom Paris by trader Sutok at Bahrat’s space station near the Nekrit Expanse. He told them that ingesting only one of the crystals would make days of tedious travel seem like moments of exquisite rapture. Chakotay and Paris immediately turned down the offer. (VOY: “Fair Trade”)

According to the novel “Pathways” by reference originator Jeri Taylor, Rhuludian crystals are formed by dehydrating the leaves of a plant, probably similar to the formation of THC crystals on dried leaves of Earth marijuana. According to the story, when the Haakonians destroyed Rinax with a metreon cascade, survivor Neelix recalls turning to smoking this narcotic substance for solace.

Rigelian gene therapy
Rigelian gene therapy was the only known medical treatment for Taggart’s Syndrome, a neurological disorder that affected Humans. Without this treatment, sufferers of the syndrome usually died by the age of twenty.

John Frederick Paxton, leader of the extremist xenophobic group, Terra Prime, suffered from Taggart’s syndrome, and took regular injections. Commander T’Pol later pointed out Paxton’s hypocrisy in utilizing the treatment, which conflicted with his views of Human purity. (ENT: “Demons”, “Terra Prime”)

Ryetalyn is the only known antidote to the deadly disease Rigelian fever. It is a rather rare mineral.

In 2269, the crew of Federation starship USS Enterprise became infected with Rigelian fever and visited the planet Holberg 917G, which had rich natural ryetalyn deposits. There they encountered the immortal Flint and his android partner Rayna Kapec. (TOS: “Requiem for Methuselah”).


A sedative was a drug used to calm down a patient or to induce sleep.

Sedatives were often administered with a hypospray in a dosage of usually not more than several ccs.

Aldebaran mud leeches could be used to treat insomnia as their secretions acted as a natural sedative. (ENT: “Anomaly”)

Captain Picard’s aunt Adele’s recipe for a warm milk toddy was working perfectly as a natural sedative, as the heat activated amino acids in the lactose and it also tasted delicious. (TNG: “Schisms”)

Constable Odo told the Rakhari criminal Croden he would sedate him if he would not be quiet during their trip to Rakhar. (DS9: “Vortex”)

Makara herbs could act as an antidote to sedatives. While taking these herbs during her pregnancy, Major Kira Nerys was able to overpower Silaran Prin by pretending the sedatives he gave her worked. (DS9: “The Darkness and the Light”)

Skin protector
A skin protector is an ointment that is administered to the skin to protect it from high levels of ultraviolet radiation that could cause skin cancer.

Kamin of Kataan developed a skin protector that he and his whole family wore to protect themselves from the dying sun of the planet, which was rapidly approaching a nova. (TNG: “The Inner Light”)

Sodium Pentathol
Sodium Pentathol (generic: thiopental sodium (C11H17N2O2SNa)) was a compound which was used as a type of “truth serum” on Earth during the mid-20th century Earth.

While he was stuck in 1947 Earth, the United States of America’ Army Air Corps used Sodium Pentathol on Quark in an attempt to gain information about an anticipated attack from Mars. However, several injections of the drug did not produce results, although Quark’s loud, high-pitched screams for mercy led Captain Wainwright to make physical threats instead. (DS9: “Little Green Men”)

Sonambutril is a strong sedative used for medical purposes. It was in use during the mid-22nd century. The chemical name is derived from the latin “somnus,” meaning “sleep.”

When Hoshi Sato and Trip Tucker caught a strain of a silicon-based virus, Phlox ordered them to use sonambutril after Sato was able to escape confinement. The sedative was able to knock out both officers for a long period of time. (ENT: “Observer Effect”)

Stenophyl is a drug that can be used to treat anaphylactic shock.

In 2375, The Doctor and the holographic Crell Moset administered stenophyl to a cytoplasmic lifeform, when it entered anaphylactic shock after being removed from B’Elanna Torres. (VOY: “Nothing Human”)

A stimulant was a type of drug intended to temporary stimulate mental or physical functions.

In 2154, when Phlox found his sleep cycle disturbed by Orion pheromones, he relied on stimulants to stay awake. (ENT: “Bound”)

During the mid-2260s, an experimental chemical stimulant designed to speed up reproduction and replacement of blood in the bodies of certain species was developed that was successfully tested in Rigelian test subjects on Rigel V. (TOS: “Journey to Babel”)

In 2374, Tim Watters took cordafin stimulants for two months while in command of the USS Valiant. (DS9: “Valiant”)

Stokaline is an injectible multiple vitamin compound. Dr. McCoy used it on Spock as a “treatment” for the Vulcan’s faked illness (a flare-up of Rigelian Kassaba fever) in the effort to regain control of the USS Enterprise from invading Kelvans. (TOS: “By Any Other Name”).

Strobolin was the cure for the choriocytosis virus.

It was a rare substance only found on a few planets in the United Federation of Planets. Given choriocytosis’ extremely rapid and deadly symptoms on some species like Vulcans, ships working in coordination were sometimes necessary to deliver the medication to stricken individuals in time. A synthesized version of the medication could be used to slow the disease’s progress, but the recipient soon became immune to its effects within hours.

When Spock contracted the virus in 2270, the USS Potemkin obtained the drug and delivered it to the USS Huron. En route to the USS Enterprise to deliver the drug, the Huron was attacked by Orion pirates, who stole the drug and the ship’s other cargo, dilithium. The Enterprise eventually recovered the drug and Leonard McCoy administered it to Spock, saving his life. (TAS: “The Pirates of Orion”)

Strychnine was an extremely poisonous white crystalline alkaloid, derived from certain plants.

In 2369, Data, in the role of Sherlock Holmes, determined that a gentleman had murdered his brother with a cigar laced with strychnine, then placed a bottle of the same in his brother’s hand. (TNG: “Ship in a Bottle”)

Synaptizine is a drug used to treat neuroleptic shock.

In 2376, The Doctor used synaptizine on Lieutenant Commander Tuvok to treat the neuroleptic shock he suffered after being attacked by the Ba’neth. (VOY: “Riddles”)

Synthetic antigen
A synthetic antigen is a manufactured anti-viral agent created from a living sample of the organism it is intended to destroy.

The Doctor created a synthetic antigen to combat an infection of the macrovirus encountered by the USS Voyager in 2373. The virus spread before The Doctor could inoculate the entire crew and eventually had to be dispersed by explosives. (VOY: “Macrocosm”)


Takeo herb
Takeo herbs are a Bajoran plant, which can be used to treat swellings. They have to be dissolved in fruit juice before being ingested.

Doctor Bashir prescribed takeo herbs to treat the swollen ankles of the pregnant Kira Nerys in 2373. (DS9: “Looking for par’Mach in All the Wrong Places”)

Talaxian wormroot
Talaxian wormroot is a plant from Talax which causes unpleasant gas pains if consumed.

In 2377, Neelix served the con artist Gar food that had been laced with Talaxian wormroot, neglecting to tell him that “some people react badly”. Neelix then told Gar that the “abdominal spasms” would worsen over thirty to forty hours, unless he revealed where he had taken The Doctor so that an antidote could be administered. (VOY: “Critical Care”)

Terakine is an analgesic medication.

In 2370, Commander William Riker received 10cc’s of terakine to alleviate the pain from a rib broken during bat’leth training with Lt. Commander Worf. (TNG: “The Pegasus”)

Tesokine was a drug used to help a baby from one species to properly metabolize the nutrients from another species while in the womb.

In 2372, tesokine was used so that Miles and Keiko O’Brien’s baby could metabolize Bajoran nutrients while Major Kira Nerys carried the baby to term. (DS9: “Body Parts”)

Tetrovaline is a medical drug used to knock a person unconscious, but which also lowers immune response.

It was carried aboard the Delta Flyer. In 2376, when Crewman Telfer had a dark matter lifeform inside him, he asked to be put under with tetrovaline, but Captain Janeway refused because he needed to keep his immune response up. (VOY: “Good Shepherd”)

Theragen is a chemical compound, initially developed as a nerve gas by the Klingons. In its pure form it is lethal, but when diluted with alcohol it can temporarily deaden certain nerve inputs to the brain, having a calming effect on an insane and/or abnormally enraged person.

A theragen derivative was first used as an effective treatment on the crew of the USS Enterprise in 2267, following an extended interaction with the effects of interphase space. Leonard McCoy, the ship’s chief medical officer, discovered how to use the theragen derivative to ameliorate the baneful effects on the crew long enough for the Enterprise to complete her mission. The medicine is now listed in the Starfleet Medical Database. (TOS: “The Tholian Web”)

Tobacco was a highly addictive and poisonous substance smoked on Earth until at least the 21st century.

During the 19th century tobacco was on sale in a shop in the Irish village of Fair Haven, if the holoprogram Paris 042 is to be believed. (VOY: “Fair Haven”)

Data would smoke a pipe when portraying Sherlock Holmes on the holodeck, as it was part of the role. (TNG: “Elementary, Dear Data”, “Ship in a Bottle”)

When Quark, Rom and Nog found themselves in 1940s Earth, virtually all of the Humans they encountered were smokers. Quark had a particularly negative reaction to the tobacco smoke. (DS9: “Little Green Men”)

Trellium is a mineral used as insulation against anomalies by starships in the Delphic Expanse. Trellium comes in multiple forms. Trellium-A is extremely common and easy to synthesize. However, it is trellium-D that is useful as insulation, and it is rare and difficult to process.

Trellium can only be synthesized in a liquid state, though the synthesized form is just as useful as the natural ore. While still a liquid it must be immediately applied to the inner hull, where it will then set. The synthesis process is very complex and very dangerous, due to the high levels of pressure and radiation involved. (ENT: “Rajiin”)

The Enterprise NX-01 visited a trellium mining planet in September of 2153 to gain information from the Xindi Kessick. (ENT: “The Xindi”) Enterprise later began to seek trellium to insulate its hull, but attempts by T’Pol and Commander Charles Tucker to synthesize trellium-D following protocols provided by the chemist B’Rat Ud proved fruitless after several weeks’ efforts, succeeding only in destroying an Enterprise science lab. (ENT: “Rajiin”) By February of 2154, Enterprise had sixty kilograms of trellium-D in its storage bay. (ENT: “Damage”)

Enterprise later discovered a trellium asteroid field while following the distress signal of the Seleya, but could not use the trellium mined there because of its effects on Vulcans. Trellium is a deadly neurotoxin to Vulcans, gradually degrading their neural pathways. This has the initial effect of removing emotional inhibitions, but will eventually induce insanity and violent rages. Over time the neurological damage becomes irreversible, eventually leading to death; this was the fate of the Seleya crew. (ENT: “Impulse”) It is likely that the Vaankara crew suffered a similar fate. (ENT: “The Expanse”) T’Pol suffered severe exposure to trellium-D while in the asteroid field, and though Doctor Phlox was able to reverse the neurological damage, she continued to hunger for the release from the constraints of logic the trellium had allowed. She developed a method of injecting it into her body and became addicted to it. With Phlox’s help, she successfully withdrew from the substance, however her ability to control her emotions to a normal Vulcan level was permanently damaged. (ENT: “Damage”)

Because of the deadly effect lining the ship’s hull would have on T’Pol, the Enterprise crew was forced to place the trellium-D mined in the asteroid field in a biohazard locker. (ENT: “Impulse”) In order to take measurements of Sphere 2, Tucker lined the hull of Shuttlepod 1 with trellium to avoid anomalies. (ENT: “Exile”)

Tri-ox compound
Tri-ox was a simple but effective intravenous medicine used for rapidly oxygenating the blood cells of a living being, especially in an oxygen-poor environment such as Vulcan. Most Humans and humanoids would otherwise have had trouble getting sufficient oxygen in such environments, especially during any strenuous work or other exertions. The drug could be used as a substitute for cumbersome breathing masks and equipment in such cases.

Tri-ox compound was designed to strengthen an individual’s cardiopulmonary system. An injection of 15 ccs of tri-ox every four hours was the recommended dosage taken to compensate for excess carbon dioxide, as could be the case of a humanoid in prolonged exposure to a Class L environment. Without it, an individual would experience the effects of hypoxia and possibly carbon dioxide poisoning. (DS9: “The Sound of Her Voice”)

Doctor Leonard McCoy feigned using tri-ox on Captain James T. Kirk in 2267 during a Vulcan combat ritual, and later used the drug on the captain after his space suit’s air supply had nearly run out. Lieutenant Commander Tuvok used tri-ox on survivors of an orbital tether carriage in 2373. (TOS: “Amok Time”, “The Tholian Web”; VOY: “Rise”)

The exact mechanism by which tri-ox worked has not been stated on screen, but it could be inferred from the instances it has been used that it increased the blood cells’ ability to bind and carry oxygen, rather than supplying additional oxygen on its own.

Trianoline was a medicine used on patients with percussive injuries.

In 2371, four ccs of trianoline was the typical dosage for a patient with a concussion. (VOY: “Caretaker”)

Triclenidil is one of the drugs used by the Angosians to enhance their soldiers during the Tarsian War. (TNG: “The Hunted”)

Tricordrazine was a potent stimulant, originally derived from cordrazine, and commonly used in resuscitation in the 24th century. The drug was highly potent; 25 ccs of the drug was enough to kill a Klingon. It was also used as an anti-seizure medication. (TNG: “Ethics”, “Shades of Gray”)

In 2365, Doctor Katherine Pulaski administered five milligrams of tricordrazine to William Riker, followed by another dose when his life signs were failing fast. (TNG: “Shades of Gray”)

In 2366, Doctor Beverly Crusher treated Mary Warren with tricordrazine after she was injured on Mintaka III, and later gave instructions for increased levels to be administered. (TNG: “Who Watches The Watchers”)

Similarly, in an alternate timeline that same year, Captain Rachel Garrett was treated with tricordrazine and Crusher ordered the levels to be boosted. (TNG: “Yesterday’s Enterprise”)

In 2368, Crusher attempted to use tricordrazine to revive Worf after he experienced heart failure, following a risky surgery using the genitronic replicator to repair his damaged spinal column. (TNG: “Ethics”)

Triglobulin is a biochemical substance produced by the Axanar zymuth gland and released into the blood. Triglobulin is used to produce medicines and vaccines, and is sometimes used as an aphrodisiac. Thus, there are cases where Axanar vessels have been attacked and triglobulin harvested from the crew. Triglobulin has certain similarities to Human lymphatic fluid. (ENT: “Fight or Flight”)

Trioxin is a medicine used in the treatment of respiratory injuries. It is used in emergency situations as a stop-gap measure, Doctors usually prefer to treat the injury itself if they have the time and capability.

In an alternate timeline, The Doctor was ordered by Captain Janeway to inject her with trioxin after her alveoli were damaged by nebular gas in 2374. (VOY: “Year of Hell, Part II”)

During the assent of orbital tether, Tuvok used trioxin to ease the effects of hypoxia on the cart’s crew. (VOY: “Rise”)

Triptacederine is an analgesic medication.

In 2370, Elim Garak used thirty ccs of triptacederine to alleviate the pain caused by his cranial implant, which would usually be enough to anesthetize an Algorian mammoth. (DS9: “The Wire”)

During the final stage of his Yarim Fel Syndrome in 2373, Tekeny Ghemor was administered triptacederine to minimize the pain. (DS9: “Ties of Blood and Water”)

An alternate spelling “triptacederin” comes from “The Wire”‘s closed captioning. In the script for “Ties of Blood and Water”, it is spelled triptacedrine.

Tropolisine is a psychotropic compound known for its hallucinogenic effects. Normally found in certain flowering plants, each tropolisine atom contains a stray neutron. Once it starts to break down in a humanoid’s bloodstream it releases an undetectable toxin.

In 2151, while exploring an uncharted M-class planet, the crew of Enterprise became affected by tropolisine that was blown down from the mountains during a windstorm. It was discovered by Dr. Phlox that inaprovaline, combined with being removed from the pollen-saturated environment would allow the effects of tropolisine to dissipate. (ENT: “Strange New World”)

By the early 23rd century, a permanent cure for the hallucinogenic effects of tropolisine had been found, allowing Humans to settle the planet.

This information was referenced in Archer’s biography found in the Starfleet database, which was discovered aboard the USS Defiant in “In a Mirror, Darkly, Part II”

Truth serum
A truth serum or truth drug was a type of drug that, when given to a humanoid, will cause them to unwillfully tell the truth. Sodium Pentathol was an example of a manufactured truth serum found on Earth. (DS9: “Little Green Men”)

In 2153, Doctor Phlox suggested to Captain Jonathan Archer that he could create a truth serum to use on Degra, in order to determine the location of Azati Prime, but added that it could take weeks to synthesize the correct formula. (ENT: “Stratagem”)

In 2266, Commander Spock suggested that a truth serum be used on uncooperative Robert Crater, so as to determine the location of the salt vampire on the surface of M-113. The salt vampire in disguise as Doctor Leonard McCoy resisted the suggestion of using it, but was in favor of it, in this case, so as not to raise suspicion. Crater, unfortunately, was killed by the salt vampire prior to the administration of the drug. (TOS: “The Man Trap”)

When Thelev was discovered to be an Orion spy serving in the Andorian delegation aboard the USS Enterprise, in 2268, he was subjected to questioning under a verifier scan and given truth drug. Unfortunately these tactics did not reveal anything, which suggested to Spock that his mind had been conditioned against such means as part of a preconceived plan. (TOS: “Journey to Babel”)

In 2369, Captain Jean-Luc Picard was drugged and interrogated by the Cardassian officer Gul Madred. (TNG: “Chain of Command, Part II”)
Chakotay is given a Kazon truth drug
Commander Chakotay was beaten and questioned with little success under some kind of truth drug by the Kazon First Maje Culluh in 2372. (VOY: “Maneuvers”)

Tryptophan-lysine distillate
Tryptophan-lysine distillate or TLD is a drug used for the treatment for a flu virus that was acquired on Nasreldine.

According to Doctor Katherine Pulaski, tryptophan-lysine distillate worked well with a generous dose of Pulaski’s chicken soup. (TNG: “The Icarus Factor”)


A vaccine is a chemical preparation that teaches a healthy immune system to fight a pathogen.

Sometime around 1960, scientists on a planet exactly like Earth developed the life prolongation complex. This was a series of viruses that became fatal when the infected individual entered puberty. In 2266, McCoy developed a vaccine that cured at least the fatal form of the disease. (TOS: “Miri”)

Vaccination is normally pointless after clinical symptoms have appeared; the immune system is already working as hard as it can, and is already aware of the threat. This suggests that by the 23rd century, physicians had broadened the term vaccine somewhat, perhaps to include therapies that stimulate the immune system beyond its normal limits, enabling it to handle particularly aggressive pathogens.

In 2364, Ligon II had a vaccine to cure Anchilles fever, which the population of Federation planet Styris IV was suffering from. The USS Enterprise-D was sent Ligon II to negotiate with Lutan, leader of the Ligonians, to acquire the vaccine. (TNG: “Code of Honor”)

In an alternate reality McCoy gave Kirk a vaccine for a viral infection spread by Melvaran mud fleas to which Kirk has a bad reaction resulting in swollen hands and numb tongue which hinder his attempt to warn Uhura about a possible Romulan attack when Nero attacked Rura Penthe in 2258. (Star Trek)

Vasokin was an experimental drug which increased blood flow to humanoid organs. Unfortunately, in 22% of studied cases it caused severe damage to the lungs, kidneys, heart, and brain.

In 2371, Dr. Julian Bashir administered vasokin to Vedek Bareil in an attempt to save his life.(DS9: “Life Support”)

Venus drug
The Venus drug was an illegal chemical compound supposedly capable of enhancing one’s most attractive qualities. Considered by many to be merely a myth, the drug was said to make women more beautiful and alluring, and men more muscular and aggressive.

In 2266, the interstellar criminal Harcourt Fenton Mudd utilized the drug on three women whom he intended to provide as wives to settlers on planet Ophiucus III. En route, however, Mudd’s starship was intercepted by the crew of the USS Enterprise, and subsequently destroyed in an asteroid belt. Mudd and the women were brought aboard the Enterprise, and Mudd subsequently hid the drug, due to its illegal nature. Later, on planet Rigel XII, Mudd used the drug in an attempt to make the women more appealing to three lithium miners, agreeing to provide the women as wives in exchange for the miners using their leverage over Captain Kirk to have Mudd freed. Kirk, however, was able to set up a ruse whereby one of the women, Eve McHuron, took colored gelatin in place of the drug and, upon witnessing Eve experience identical effects as that of the actual drug, and prove that the drug’s power actually resided in the user’s self-confidence and belief in their own attractiveness. (TOS: “Mudd’s Women”)

Veridium Six
Veridium Six was a poison effective against Klingons. It has no known antidote.

In early 2367, Chancellor K’mpec was poisoned with Veridium Six. The poison slowly built up through small doses introduced into his bloodwine until the level became fatal. (TNG: “Reunion”)

Vertazine was a drug typically administered in a hypospray to remedy dizziness.

Dr. Crusher gave La Forge a dose of vertazine after he experienced an episode of dizziness while working in Main Engineering. (TNG: “Cause and Effect”)

Whenever Worf transported between quantum realities he experienced dizziness. Following one transition, Dr. Crusher offered to give Worf some vertazine, to counteract the side effects of the concussion that he suffered in that quantum reality. (TNG: “Parallels”)

Vitalizer B
Vitalizer B was a Federation stimulant drug.

Vitalizer B was used by Starfleet’s Dr. Leonard McCoy in 2268 to treat Spock when he was shot in the back with a flintlock firearm. (TOS: “A Private Little War”)

Voraxna is a type of poison effective against Cardassians.

In 2373, Dukat had voraxna added to a bottle of kanar, which was then delivered to Tekeny Ghemor.

Benjamin Sisko later confronted Dukat and Weyoun with the poisoned kanar, which according to him was enough to kill a dozen Cardassians. Weyoun drank the kanar and the poison, saying it was “quite toxic”. Fortunately for Weyoun, Vorta were immune to most forms of poison. (DS9: “Ties of Blood and Water”)


Zenite is a mineral that was useful in countering plant diseases. In 2269, it was found only on Ardana in soft ore material, and hand removal was the preferred method of mining.

However, the Ardanans were apparently unaware that the mineral in its raw state has an undesirable by-product: it emits a colorless and odorless gas that temporarily impairs synaptic functions, stunting the subject’s intelligence and emotional control. When the subject is removed from a high concentration of the gas, brain functions return to normal.

This medical problem was discovered by Dr. Leonard McCoy, who also learned that a simple air filter was sufficient to prevent exposure. However, the Ardanans were reluctant to accept these facts, and only after concerted diplomatic efforts did they agree to take prescribed safety precautions for mining. (TOS: “The Cloud Minders”)
