During the last years in Germany a marked increase in the use of amphetamines such as 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) has been observed. The use of these recreational drugs is especially common among young people participating in rave parties. Occasionally ring-methoxylated phenethylamine derivatives like paramethoxymethamphetamine (PMMA) or paramethoxyamphetamine (PMA) are fo...

background ecstasy or 3-4, methylenedioxymethamphetamine (mdma), as an amphetamine derivate, could lead to learning and memory impairment. objectives as the hippocampus is responsible for learning and memory, herein we evaluated acute and chronic effects of mdma on the structure of the hippocampus. materials and methods male wistar rats (200-250 g) received single or multiple injections of mdma...

Introdução: O transtorno de estresse pós-traumático (TEPT) se caracteriza pela persistência reações intensas a lembranças um evento traumático. Nos últimos anos, houve uma série estudos neurocientíficos e clínicos examinando o potencial 3,4-metilenodioxmetanfetamina (MDMA) como tratamento para do pós-traumático. objetivo desse estudo é sintetizar os disponíveis em busca melhores informações sob...

Administration of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) to various experimental animals has been shown to induce a selective damage to serotonergic axon terminals. While a great consensus appears to exist regarding the causative role of reactive oxygen species (ROS) in the mechanisms underlying MDMA toxicity, the source of free radicals is still a matter of debate. While some author...

"Club drugs" have become alarmingly popular. The use of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) and gamma-hydroxybutyrate (GHB), in particular, has increased dramatically from 1997-1999. The pharmacokinetics of MDMA and GHB appear to be nonlinear, making it difficult to estimate a dose-response relationship. The drug MDMA is an amphetamine analog with sympathomimetic properties, where...

MDMA (3,4-methylenedioxy-methylamphetamine, a.k.a. "ecstasy") was first synthesized in 1912 and resynthesized more than once for pharmaceutical reasons before it became a popular recreational drug. Partially based on previously overlooked U.S. government documentation, this article reconstructs the early history of MDMA as a recreational drug in the U.S. from 1960 to 1979. According to the lite...

OBJECTIVE "Ecstasy," or 3,4-methylenedioxymethamphetamine (MDMA), causes long-term impairment to the serotonin (5-HT) system in rats, dogs, and nonhuman primates. 5-HT dysfunction has also been observed in human recreational users of the drug, but whether 5-HT dysfunction in humans is caused by MDMA has not been established, since dysfunction may have preceded MDMA exposure. This ambiguity abou...

3,4-Methylenedioxymethamphetamine (MDMA or "Ecstasy") is a psychoactive and hallucinogenic drug of abuse. MDMA has been shown to produce neurotoxicity both in animals and humans. MDMA and other amphetamines induce serotonergic and dopaminergic terminal neurotoxicity and also neurodegeneration in areas including the cortex, hippocampus, striatum and thalamus. Herein, we investigated the mechanis...

3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is a popular recreational drug. The aim of the present study was to explore the role of dopamine in the psychotropic effects of MDMA using bupropion to inhibit the dopamine and norepinephrine transporters through which MDMA releases dopamine and norepinephrine by investigating. The pharmacodynamic and pharmacokinetic interactions between bupro...
