AIMS To review the thermal effects of MDMA in humans, and discuss the practical implications. METHODS The literature on Ecstasy/MDMA, body temperature, and subjective thermal self-ratings was reviewed, and explanatory models for the changes in thermal homeostasis were examined and debated. RESULTS In human placebo-controlled laboratory studies, the effects of MDMA were dose related. Low dos...

We previously showed that developmental 3,4-methylenedioxymethamphetamine (MDMA) treatment induces long-term spatial and egocentric learning and memory deficits and serotonin (5-HT) reductions. During brain development, 5-HT is a neurotrophic factor influencing neurogenesis, synaptogenesis, migration, and target field organization. MDMA (10 mg/kg × 4/d at 2 h intervals) given on post-natal day ...

The aim of this investigation was to examine the effect of 3,4-methylenedioxymethamphetamine (MDMA) administration on arginine vasopressin (AVP) release. (R,S)-MDMA (40 mg) was administered to eight normally hydrated healthy male volunteers (22-32 years) and blood samples were collected up to 24 h. Plasma was assayed for AVP and cortisol by radioimmunoassays, and for MDMA and the N-demethylated...

MDMA (3,4-methylenedioxymethamphetamine) or 'Ecstasy' is a widely used recreational drug that produces a state of heightened mood but also cardiovascular and vegetative side-effects. In animals, MDMA releases serotonin and, to a lesser extent, dopamine and norepinephrine. The release of serotonin can be blocked by serotonin uptake inhibitors such as citalopram. It is unknown to what extent this...

A wider array of treatments are needed for people with substance abuse disorders. Some psychedelic compounds have been assessed as potential substance abuse treatments with promising results. MDMA may also help treat substance abuse based on shared features with psychedelic compounds and recent reports indicating that MDMAassisted psychotherapy can reduce symptoms of PTSD. Narrative reports and...

The party drug 3,4-methylenedioxymethamphetamine -better known as MDMA or ecstasy- has numerous effects on the human body, characterized by a rush of energy, euphoria and empathy. However, also a multitude of toxic/neurotoxic effects have been ascribed to MDMA, based upon case reports and studies in animals. Given the intrinsic difficulties associated with controlled studies in human beings, mo...

Currently, joint use of ketamine and 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) represents a specific combination of polydrug abuse. Long-lasting and even aggravated central neuronal toxicity associated with mixing ketamine and MDMA use is of special concern. This study was undertaken to examine the modulating effects of ketamine treatment on later MDMA-induced dopamine and serotonin neu...

BACKGROUND Little is known concerning the enantioselective disposition of 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) in humans. In addition, the potential of utilizing the stereochemical composition of an analyte in biological media for forensic purposes requires investigation. METHODS The enantiomers of MDMA and its demethylated metabolite, 3,4-methylenedioxyamphetamine (MDA), present...

Background Social anxiety disorder (SAD) is a serious and prevalent psychiatric condition that heavily impacts social functioning quality of life. Though efficacious treatments exist for SAD, remission rates remain elevated significant portion those affected do not access effective treatment, suggesting the need additional evidence-based treatment options. This paper presents protocol an open-l...

BACKGROUND: 3, 4-methylenedioxymethamphetamine (MDMA, also known as "ecstasy") has been shown to exhibit neurotoxic effects on the hippocampus. However, exposure to sub-lethal insults of MDMA has been reported to result in neuroprotection. OBJECTIVE: To investigate the effects of MDMA on hippocampal neuronal viability, caspase-3 activity, and mRNA expression of the N-methyl-D-aspartate (NMDA) r...
