In Western societies, a considerable percentage of young people use 3,4-methylenedioxymethamphetamine (MDMA or ‘ecstasy’). The use of alcohol (ethanol) in combination with ecstasy is common. The aim of the present study was to assess the acute psychomotor and subjective effects of (co-) administration of MDMA and ethanol over time and in relation to the pharmacokinetics. We performed a...

The poly-drug pattern is the most common among those observed in MDMA users, with cocaine being a frequently associated drug. This study evaluates the acute effects of MDMA (5, 10 and 20 mg/kg), alone or in combination with cocaine (25 mg/kg), on motor activity, anxiety (elevated plus maze and social interaction test), memory and brain monoamines in adolescent mice. Both drugs, administered...

The amphetamine-derived designer drugs have been illegally used worldwide as recreational drugs, some of which are known to be hepatotoxic in humans. To compare their cytotoxic effects, 3,4-methylenedioxy-N-methamphetamine (MDMA) and its related analogues, N-methyl-1-(3,4-methylenedioxyphenyl)-2-butanamine (MBDB), 3,4-(methylenedioxyphenyl)-2-butanamine (BDB) and...

(+/-)-3,4-Methylenedioxymethamphetamine (MDMA) is a commonly abused illicit drug which affects multiple organ systems. In animals, high-dose administration of MDMA produces deficits in serotonin (5-HT) neurons (e.g., depletion of forebrain 5-HT) that have been viewed as neurotoxicity. Recent data implicate MDMA in the development of valvular heart disease (VHD). The present paper reviews...

Methylenedioxymethamphetamine (MDMA, ecstasy) is a widely used recreational drug, often associated with dance parties. Users self-report euphoria, a sense of well-being and increased feelings of affiliation. In experimental animals, MDMA produces an acute, rapid release of serotonin and, to a lesser extent, dopamine and norepinephrine in the brain. It can also produce a dose-dependent,...

Users of the popular party drug 3,4-methylenedioxymethamphetamine (MDMA) sometimes report combining MDMA with γ-hydroxybutyrate (GHB) to enhance the pleasurable effects of both drugs. However, very few studies have examined the influences of this drug combination. The present study investigated the development of locomotor sensitization in laboratory rats given 7 once-weekly exposures to either...

Introduction. The consumption of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) is known to cause severe hyperthermia in humans. This is of extreme importance since ecstasy is often consumed at 'rave' parties, where dancing takes place in a warm environment, which may exacerbate the effect of MDMA on thermoregulation. The present study was performed in order to evaluate the effects of single...

Acute ingestion of MDMA (ecstasy) causes a transient marked increase in serotonin and dopamine at central synapses. Recent studies demonstrated that MDMA induces damage of serotonergic nerve terminals and alters hippocampal processing. Pronounced cognitive deficits in MDMA users affect learning and memory abilities. This pattern of predominant and long-lasting memory dysfunction suggests that...

Previous research has suggested that the separate aspects of executive functioning are differentially affected by ecstasy use. Although the inhibition process appears to be unaffected by ecstasy use, it is unclear whether this is true of heavy users under conditions of high demand. Tasks loading on the updating process have been shown to be adversely affected by ecstasy use. However, it remains...

Although use of 'ecstasy' (drugs sold as containing 3,4-methylenedioxymethamphetamine) is prevalent, it is typically infrequent, and treatment presentations involving ecstasy as a principal problem drug are relatively rare. Human case reports and animal literature suggest dependence potential, although there may be some unique aspects to this syndrome for ecstasy in comparison to other...
