Amphetamine is a central nervous system (CNS) stimulant that is used in the treatment of attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity. Amphetamine was discovered as a chemical in 1887 by Lazăr Edeleanu, and then as a drug in the late 1920s. It exists as two enantiomers: levoamphetamine and dextroamphetamine. Amphetamine properly refers to a specific chemical, the racemic free base, which is equal parts of the two enantiomers in their pure amine forms. The term is frequently used informally to refer to any combination of the enantiomers, or to either of them alone. Historically, it has been used to treat nasal congestion and depression. Amphetamine is also used as an athletic performance enhancer and cognitive enhancer, and recreationally as an aphrodisiac and euphoriant. It is a prescription drug in many countries, and unauthorized possession and distribution of amphetamine are often tightly controlled due to the significant health risks associated with recreational use.
Stimulants are a class of drugs that increase the activity of the brain and the spinal cord. They are used for various purposes, such as enhancing alertness, attention, motivation, cognition, mood, and physical performance. Some of the most common stimulants are caffeine, nicotine, amphetamine, methamphetamine, cocaine, and modafinil.
Empathogens or entactogens are a class of psychoactive drugs that induce the production of experiences of emotional communion, oneness, relatedness, emotional openness—that is, empathy or sympathy—as particularly observed and reported for experiences with 3,4-methylenedioxymethamphetamine (MDMA). This class of drug is distinguished from the classes of hallucinogen or psychedelic, and amphetamine or stimulants. Major members of this class include MDMA, MDA, MDEA, MDOH, MBDB, 5-APB, 5-MAPB, 6-APB, 6-MAPB, methylone, mephedrone, GHB, αMT, and αET, MDAI among others. Most entactogens are phenethylamines and amphetamines, although several, such as αMT and αET, are tryptamines. When referring to MDMA and its counterparts, the term MDxx is often used. Entactogens are sometimes incorrectly referred to as hallucinogens or stimulants, although many entactogens such as ecstasy exhibit psychedelic or stimulant properties as well.
A paradoxical reaction is an effect of a chemical substance, such as a medical drug, that is opposite to what would usually be expected. An example of a paradoxical reaction is pain caused by a pain relief medication.
Propylhexedrine, commonly sold under the brand name Benzedrex, is an alkylamine primarily utilized as a topical nasal decongestant. Its main indications are relief of congestion due to colds, allergies, and allergic rhinitis.
Camazepam is a benzodiazepine psychoactive drug, marketed under the brand names Albego, Limpidon and Paxor. It is the dimethyl carbamate ester of temazepam, a metabolite of diazepam. While it possesses anxiolytic, anticonvulsant, skeletal muscle relaxant and hypnotic properties it differs from other benzodiazepines in that its anxiolytic properties are particularly prominent but has comparatively limited anticonvulsant, hypnotic and skeletal muscle relaxant properties.
Ambroxol is a drug that breaks up phlegm, used in the treatment of respiratory diseases associated with viscid or excessive mucus. Ambroxol is often administered as an active ingredient in cough syrup.
Pyrovalerone is a psychoactive drug with stimulant effects via acting as a norepinephrine-dopamine reuptake inhibitor (NDRI). It was developed in the 1980s and had briefly been approved in Spain and France for chronic fatigue or lethargy and as an anorectic or appetite suppressant, but was withdrawn from both markets around 2001 due to safety concerns including problems with abuse and dependence. It is closely related on a structural level to a number of other cathinone stimulants, such as α-PVP, MDPV and prolintane.
α-Pyrrolidinopropiophenone (α-PPP), is a stimulant drug. It is similar in structure to the appetite suppressant diethylpropion and has analogous effects in animals. Little is known about this compound, but it has been detected by laboratories in Germany as an ingredient in "ecstasy" tablets seized by law enforcement authorities. This drug has been found to produce stimulant effects in animals and presumably also produces these effects in humans, based on the context in which it has been found.
Befuraline (DIV-154) is a psychoactive drug and member of the piperazine chemical class which was developed in Germany in the 1970s. Befuraline has stimulant and antidepressant effects and has seen some use in Germany and France, although it has never become widely used. Befuraline's active metabolite benzylpiperazine is likely to contribute to its effects.
Mesocarb is a drug that is currently being developed for Parkinson's disease.
Feprosidnine (Sydnophen) is a stimulant drug which was developed in the USSR in the 1970s. It is structurally related to another Russian drug mesocarb but unlike mesocarb, was withdrawn earlier from production. In comparison with mesocarb it has own antidepressant activity, which makes it useful in treating depressions. Indications of feprosidnine included apathic, asthenic depressions, fatigue, apathic syndrome, narcolepsy and other similar conditions. Therapeutic range of doses: 10-50mg a day. Sydnophen has multiple mechanisms of action, the relative importance of which has not been clearly established. Effects on the body include reversible monoamine oxidase inhibition, cholinergic, adrenergic, opioid and nitric oxide donating actions, all of which may contribute to its pharmacological effects to some extent.
Levoamphetamine is a central nervous system (CNS) stimulant known to increase wakefulness and concentration in association with decreased appetite and fatigue. Pharmaceuticals that contain levoamphetamine are currently indicated and prescribed for the treatment of attention deficit hyperactivity disorder (ADHD), obesity, and narcolepsy in some countries.
Pentorex (Modatrop), also known as phenpentermine or α,β-dimethylamphetamine, is a stimulant drug related to phentermine which is used as an anorectic to assist with weight loss. It also acts as a diuretic. Pentorex was developed by Nordmark in the 1960s.
TDIQ is a drug used in scientific research, which has anxiolytic and anorectic effects in animals. It has an unusual effects profile in animals, with the effects generalising to cocaine and partially to MDMA and ephedrine, but the effects did not generalise to amphetamine and TDIQ does not have any stimulant effects. It is thought these effects are mediated via a partial agonist action at Alpha-2 adrenergic receptors, and TDIQ has been suggested as a possible drug for the treatment of cocaine dependence.
Arylcyclohexylamines, also known as arylcyclohexamines or arylcyclohexanamines, are a chemical class of pharmaceutical, designer, and experimental drugs.
Substituted amphetamines are a class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting, one or more hydrogen atoms in the amphetamine core structure with substituents. The compounds in this class span a variety of pharmacological subclasses, including stimulants, empathogens, and hallucinogens, among others. Examples of substituted amphetamines are amphetamine (itself), methamphetamine, ephedrine, cathinone, phentermine, mephentermine, tranylcypromine, bupropion, methoxyphenamine, selegiline, amfepramone (diethylpropion), pyrovalerone, MDMA (ecstasy), and DOM (STP).
Amfecloral (INN), also known as amphecloral (USAN), is a stimulant drug of the phenethylamine and amphetamine chemical classes that was used as an appetite suppressant under the trade name Acutran, but is now no longer marketed. It was classified as an anorectic drug with little to no stimulant activity in a 1970 review. The British Pharmacopoeia Commission approved the name in 1970. The raw ingredients used in manufacturing it were d-amphetamine and chloral hydrate.
Fenpentadiol (INN), also known as phenpentanediol, is a drug described as a tranquilizer and antidepressant that was formerly marketed in Europe. It also has stimulant, sedative, and anxiolytic effects, with the latter two occurring only at higher doses.
G-130 is a drug with stimulant and anorectic effects, related to phenmetrazine.
