Phase II trials of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy have demonstrated initial safety and efficacy for treatment of posttraumatic stress disorder (PTSD), with potential for expansion to depression and anxiety disorders. In these trials, single doses of MDMA are administered in a model of medication-assisted psychotherapy, differing from trials involving daily drug ...

3,4-Methylenedioxymethamphetamine (MDMA) has previously been shown to destroy serotonin terminals in the rat brain. Despite profound and prolonged loss of serotonin innervation, long-term behavioral effects of MDMA have not previously been reported. In this study, we monitored the short- and long-term effects of MDMA administration on the ultrasonic isolation call of the rat pup. At 30 to 60 mi...

3,4-Methylenedioxymethamphetamine (MDMA), a common recreational drug, is known to cause serotonergic neurotoxicity in the brain. Dextromethorphan (DM) is a widely used antitussive reported to exert anti-inflammatory effect in vivo. In this study, we examined the long-term effect of MDMA on the primate serotonergic system and the protective property of DM against MDMA-induced serotonergic abnorm...

3,4-Methylenedioxymethamphetamine (MDMA; "Ecstasy") increases body temperature. This process could be associated with increased cutaneous blood flow, as normally occurs with exercise-induced hyperthermia. Alternatively, an MDMA-induced fall in cutaneous blood flow could contribute to the hyperthermia by diminishing normal heat transfer from the body to the environment. We investigated these pos...

The present study was designed to elucidate the role of dopamine (DA) metabolism in the serotonergic neurotoxicity induced by 3,4-methylenedioxymethamphetamine (MDMA). An antisense (AS) oligonucleotide (ODN) sequence targeted at monoamine oxidase-B (MAO-B) was utilized to attenuate MAO-B activity prior to MDMA administration. Sprague-Dawley rats were surgically implanted with intracerebroventri...

A case of an apparently natural death in association with the use of an MDMA (3,4-methylenedioxymethamphetamine) is reported. The pathophysiology of the death and the pharmacology of the drug are presented. An overview of the certification of such cases is briefly presented.

Decision-making, i.e. selecting an action from a number of alternatives when the outcome is uncertain, is a complex process that is important for everyday life. 3,4-Methylenedioxymethamphetamine (MDMA), also known as 'Ecstasy', is a widely used recreational drug that is known to increase serotonin (5-HT) and, to a lesser extent, dopamine (DA) in animals. This study examined whether MDMA alters ...

3,4-Methylenedioxymethamphetamine (MDMA) is an illicit psychoactive drug with cardiovascular effects that have not been fully described. In the current study, we observed the effects of acute MDMA on rabbit left ventricular function. We also observed the effects of MDMA on nuclear factor-kappa B (NF-κB) activity in cultured rat ventricular myocytes (H9c2). In the rabbit, MDMA (2 mg/kg) alone ca...

The delta opioid system is involved in the behavioral effects of various drugs of abuse. However, only a few studies have focused on the possible interactions between the opioid system and the effects of 3,4-methylenedioxymethamphetamine (MDMA). In order to examine the possible role of the delta opioid system in MDMA-induced behaviors in mice, locomotor activity and conditioned place preference...
