The effects of (+/-)-methylenedioxymethamphetamine and (+/-)-methylenedioxyamphetamine in monkeys trained to discriminate (+)-amphetamine from saline. 1986

J B Kamien, and C E Johanson, and C R Schuster, and W L Woolverton

Recently, attention has been focused on (+/-)-methylenedioxymethamphetamine (MDMA), a psychotomimetic agent chemically closely related to the psychomotor stimulant methamphetamine, and also to the hallucinogen mescaline. In the present experiment, the effects of MDMA and (+/-)-3,4-methylenedioxyamphetamine (MDA) were determined in rhesus monkeys that were trained to discriminate intravenously administered (+)-amphetamine (AMPH) from saline in a two-lever, food-maintained paradigm or to discriminate intragastrically administered AMPH from saline in a signalled electric shock avoidance paradigm. MDMA produced 100% drug-appropriate responding in all six monkeys, regardless of the procedure and route of administration while MDA substituted completely for AMPH in only two of three monkeys in each paradigm. The results suggest that MDMA has subjective effects that are similar to those of AMPH while MDA is somewhat less like AMPH.

D000661	Amphetamine	A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.

D000662	Amphetamines	Analogs or derivatives of AMPHETAMINE. Many are sympathomimetics and central nervous system stimulators causing excitation, vasopressin, bronchodilation, and to varying degrees, anorexia, analepsis, nasal decongestion, and some smooth muscle relaxation.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
