3,4-methylenedioxymethamphetamine (MDMA; ecstasy) is a commonly abused recreational drug that causes neurotoxic effects in both humans and animals. The mechanism behind MDMA-induced neurotoxicity is suggested to be species-dependent and needs to be further investigated on the cellular level. In this study, the effects of MDMA in neuronally differentiated P19 mouse embryonal carcinoma cells have...

Our society looks upon psychiatric drugs with such naive trust that it raises the moral, societal and "therapeutic" status of an illegal drug when it can be compared to a psychiatric drug. Thus Matthew Klam's personal account in the January 21, 2001 New York Times Magazine praised the amphetamine Ecstasy as a ''whooper of an antidepressant" that is better than Prozac®. Although illegal in the U...

The widely abused amphetamine analog 3,4-methylenedioxymethamphetamine (MDMA, also called "ecstasy") induces hallucination and psychostimulation, as well as long-term neuropsychiatric behaviors such as panic and psychosis. In rodents and monkeys, MDMA is cytotoxic to serotonergic neurons, but this is less clear with humans. Herein, MDMA was cytotoxic to human serotonergic JAR cells; it altered ...

3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is a designer drug commonly misused in large segments of young populations. MDMA is usually formulated in tablets of its racemate (1:1 mixture of its enantiomers) in doses ranging from 50 to 200 mg. MDMA has an enantioselective metabolism, the (S)-enantiomer being metabolized faster than the (R)-enantiomer. Different pharmacologic properties h...

Use of the popular club drug ecstasy (3,4-methylenedioxymethamphetamine, MDMA) can result in life-threatening hyperthermia and rhabdomyolysis. Recent studies show a link between skeletal muscle uncoupling proteins in MDMA-mediated hyperthermia. The mechanisms by which MDMA interacts with skeletal muscle mitochondria are largely unknown. The present study was designed to comprehensively evaluate...

3,4-methylenedioxymethamphetamine (mdma) or ecstasy, has had a widely spread popularity among young adults in recent years. kidney toxicity is one of the consequences of ecstasy. the studies have shown that ecstasy is metabolized by cytochrome p450 to reactive electrophil metabolites which detoxify by glutathione (gsh) conjugation. to our knowledge in vivo study of the effect of glutathione on ...

Understanding the diverse functions of serotonin in the human brain can be obtained through examination of subjects having a lower than normal number of brain serotonin neurons. Behavioral abnormalities consistent with brain serotonergic damage have been reported in some polydrug users who also use the neurotoxin ecstasy (methylenedioxymethamphetamine, MDMA). This review evaluates the evidence ...

BACKGROUND MDMA (3,4-methylenedioxymethamphetamine, 'Ecstasy') produces tachycardia and hypertension and is rarely associated with cardiovascular and cerebrovascular complications. In clinical practice, beta-blockers are often withheld in patients with stimulant intoxication because they may increase hypertension and coronary artery vasospasm due to loss of beta(2)-mediated vasodilation and uno...

Background: 3,4- methylenedioxymethamphetamine (MDMA) is a chemical derivative of amphetamine that can induce learning and memory impairment. Due to the effect of neurotrophins on memory and learning, the impact of MDMA was evaluated on the brain - derived neurotrophic factor (BDNF), neurotrophin- 4 (NT-4), and tropomyosin- related kinase B (Trk- β) expression in the hippocampus. Methods: In th...
