Stimulants

Bromantane, sold under the brand name Ladasten, is an atypical central nervous system (CNS) stimulant and anxiolytic drug of the adamantane family that is related to amantadine and memantine. Medically, it is approved in Russia for the treatment of neurasthenia. Although the effects of bromantane have been determined to be dependent on the dopaminergic and possibly serotonergic neurotransmitter systems, its exact mechanism of action is unknown, and is distinct in its properties relative to typical stimulants such as amphetamine. Bromantane has sometimes been described as an actoprotector (synt

Pipradrol, also known by its brand name Meratran, is a mild central nervous system stimulant that acts as a norepinephrine-dopamine reuptake inhibitor. Developed in the United States in the 1940s and patented in 1953, pipradrol was initially marketed as an antidepressant in the mid-1950s. It was subsequently used as an adjunct treatment for various conditions, including obesity, senile dementia, narcolepsy, and schizophrenia.

Pitolisant, sold under the brand name Wakix among others, is a medication used for the treatment of excessive daytime sleepiness in adults with narcolepsy. It is an inverse agonist of the histamine H3 receptor.

Pitolisant enhances the activity of histaminergic neurons in the brain that function to improve a person's wakefulness. It was approved by the European Medicines Agency (EMA) in March 2016 for narcolepsy with or without cata

Amiphenazole (Daptazile) is a respiratory stimulant traditionally used as an antidote for barbiturate or opiate overdose, usually in combination with bemegride, as well as poisoning from other sedative drugs and treatment of respiratory failure from other causes. It was considered particularly useful as it could counteract the sedation and respiratory depression produced by morphine but with less effect on analgesia. It is still rarely used in medicine in some countries, although it has largely been replaced by more effective respiratory stimulants such as doxapram and specific opioid antagoni

D-IX is a methamphetamine-based experimental performance enhancer developed by Nazi Germany in 1944 for military application. The researcher who rediscovered this project, Wolf Kemper, said, "the aim was to use D-IX to redefine the limits of human endurance." One dose contained 5 mg oxycodone (brand name Eukodal, an analgesic opioid), 5 mg cocaine, and 3 mg methamphetamine (brand name Pervitin).

Dimethocaine, also known as DMC or larocaine, is a compound with a stimulatory effect. This effect resembles that of cocaine, although dimethocaine appears to be less potent. Just like cocaine, dimethocaine is addictive due to its stimulation of the reward pathway in the brain. However, dimethocaine is a legal cocaine replacement in some countries and is even listed by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) under the category "synthetic cocaine derivatives". The structure of dimethocaine, being a 4-aminobenzoic acid ester, resembles that of procaine. It is found a

ZK-93426 (ethyl-5-isopropoxy-4-methyl-β-carboline-3-carboxylate) is a drug from the β-carboline family. It acts as a weak partial inverse agonist of benzodiazepine receptors, meaning that it causes the opposite effects to the benzodiazepine class of drugs and has anxiogenic properties, although unlike most benzodiazepine antagonists it is not a convulsant and actually has weak anticonvulsant effects. In human tests it produced alertness, restlessness and feelings of apprehension, and reversed the effect of the benzodiazepine lormetazepam. It was also shown to produce nootropic effects and incr

Xylopropamine, also known as 3,4-dimethylamphetamine (DMeA) and sold under the brand names Perhedrin and Esanin, is a stimulant drug of the phenethylamine and amphetamine families which was developed and marketed as an appetite suppressant in the 1950s.

It displayed a favorable therapeutic index and margin of safety in comparison to most other pemoline derivatives. The patents concluded that cyclazodone possessed properties efficacious in reducing fatigue and as a potential anorectic. Structural congeners of pemoline have been described as "excitants with unique properties distinguishing them from the sympathomimetic amines" whilst displaying less stimulatory activity and to

6-APB, also known as 6-(2-aminopropyl)benzofuran, is an entactogen of the phenethylamine, amphetamine, and benzofuran families. 6-APB and related drugs are sometimes informally called "Benzofury" in media reports.

Famprofazone (Gewodin, Gewolen) is a nonsteroidal anti-inflammatory agent (NSAID) of the pyrazolone series which is available over-the-counter in some countries such as Taiwan. It has analgesic, anti-inflammatory, and antipyretic effects. Famprofazone has been known to produce methamphetamine as an active metabolite, with 15–20% of an oral dose being converted to it.

Pozanicline (INN, codenamed ABT-089) is a drug developed by Abbott, that has nootropic and neuroprotective effects. Animal studies suggested it useful for the treatment of ADHD and subsequent human trials have shown ABT-089 to be effective for this application. It binds with high affinity subtype-selective to the α4β2 nicotinic acetylcholine receptors and has partial agonism to the α6β2 subtype, but not the α7 and α3β4 subtypes familiar to nicotine.

Despite study of the molecule since 1990s, as of 2025 it has not been shown to be effective in clinical trials.

4-Methylethcathinone or 4-MEC is a chemical that bears a chemical resemblance to mephedrone. Due to its similarity to mephedrone, it is thought to be a stimulant and entactogen drug of the phenethylamine, amphetamine, and cathinone chemical classes. It has been marketed alone or in mixtures with other substituted cathinones under the name "NRG-2", although other blends such as "NRG-1" may have been more ambiguous with their ingredients.

Cypenamine (INN, BAN), or cypenamine hydrochloride (USAN), also known as 2-phenylcyclopentylamine, is a psychostimulant drug which was developed by a group at the William S. Merrell Chemical Company in the 1940s. It is currently known only in scientific research and has never been developed for market use. Cypenamine is currently legal throughout the entire world, and though its chemical structure has a vague similarity to certain controlled stimulants like fencamfamine, it is likely that it is too distant for it to be considered an illicit analogue under the United States Federal Analogue Act

Cyclopentamine (trade names Clopane, Cyclonarol, Cyclosal, Cyklosan, Nazett, Sinos, among others) is a sympathomimetic and vasoconstrictor drug of the alkylamine family and related to the arylalkylamines.

Manifaxine was researched for treatment of attention deficit hyperactivity disorder (ADHD) and obesity and was found to be safe, reasonably effective, and well-tolerated for both applications. However, no results were reported following these initial trials and development was discontinued.
