Methylenedioxymethamphetamine (MDMA, 'Ecstasy'): Neurodegeneration versus Neuromodulation

Pharmaceuticals July 5, 2011 Elena Puerta, Norberto Aguirre 6 citations

The amphetamine analogue 3,4-methylenedioxymethamphetamine (MDMA, ‘ecstasy’) is widely abused as a recreational drug due to its unique psychological effects. Of interest, MDMA causes long-lasting deficits in neurochemical and histological markers of the serotonergic neurons in the brain of different animal species. Such deficits include the decline in the activity of tryptophan hydroxylase in...

Sleep apnea in young abstinent recreational MDMA (“ecstasy”) consumers

Neurology July 4, 2011 Una D. Mccann, Francis P. Sgambati, Alan R. Schwartz et al. 1 citation

Background: Methylenedioxymethamphetamine (MDMA, "ecstasy") is a popular recreational drug of abuse and a selective brain serotonin neurotoxin.Functional consequences of MDMA neurotoxicity have defied ready characterization.Obstructive sleep apnea (OSA) is a common form of sleep-disordered breathing in which brain serotonin dysfunction may play a role.The present study sought to determine...

A Caenorhabditis elegans p38 MAP kinase pathway mutant protects from dopamine, methamphetamine, and MDMA toxicity.

Neuroscience Letters July 1, 2011 Matthew A Schreiber, Steven L McIntire

Biogenic amine systems are damaged by amphetamine abuse and in Parkinson's disease. The mechanisms mediating this damage are of high importance because of the public health impact of these problems. Here we have taken advantage of the Caenorhabditis elegans nematode model system to investigate genetic modifiers of biogenic amine toxicity. In a forward genetic screen, we identified a mutant...

[Ambient temperature impact on hepatocellular liver damage in rats following intake of 3,4-methylenedioxymethamphetamine].

Vojnosanitetski Pregled July 2011 Nadica S Marinković, Zivorad Malicevic, Jovan Dimitrijević

3,4-methylendioxymethamphetamine (MDMA, Ecstasy) is a psycho-stimulating agent. It is usually taken orally in the form of tablets. It is absorbed throught the gastrointestinal mucous membrane. Hyperthermia is the most prominent clinical sign of MDMA intake. The most prominent forensic finding of lethal MDMA poisoning is myocardial infarction and cerebrovascular bleeding. However, liver and...

Metabolism and disposition of 3,4-methylenedioxymethamphetamine ("ecstasy") in baboons after oral administration: comparison with humans reveals marked differences.

Journal of Pharmacology and Experimental Therapeutics July 2011 Melanie Mueller, Amy K Goodwin, Nancy A Ator et al.

The baboon is potentially an attractive animal for modeling 3,4-methylenedioxymethamphetamine (MDMA) effects in humans. Baboons self-administer MDMA, are susceptible to MDMA neurotoxicity, and are suitable for positron emission tomography, the method most often used to probe for MDMA neurotoxicity in humans. Because pharmacokinetic equivalence is a key feature of a good predictive animal model,...

The Role of MDMA (Ecstasy) in Coping with Negative Life Situations Among Urban Young Adults

Journal of Psychoactive Drugs July 1, 2011 Lwendo S. Moonzwe, Jean J. Schensul, Kristin M. Kostick 21 citations

This article examines the role of Ecstasy (MDMA or 3, 4-methylenedioxymethamphetamine) as a drug used for self-medication and coping with both short- and long-term negative life situations. We show that urban youth who do not have a specific diagnosed mental illness are more likely than those who have been diagnosed and have received treatment to use Ecstasy to cope with both situational stress...

A direct comparison of the behavioral and physiological effects of methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA) in humans

Psychopharmacology June 30, 2011 M. Kirkpatrick, Erik W. Gunderson, Audrey Y. Perez et al. 119 citations

Despite their chemical similarities, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA) produce differing neurochemical and behavioral responses in animals. In humans, individual studies of methamphetamine and MDMA indicate that the drugs engender overlapping and divergent effects; there are only limited data comparing the two drugs in the same individuals. This study examined the...

Sex Differences in the Effects of MDMA (Ecstasy) on Plasma Copeptin in Healthy Subjects

The Journal of Clinical Endocrinology & Metabolism June 30, 2011 Linda D. Simmler, Cédric M. Hysek, Matthias E. Liechti 91 citations

Abstract Background: 3,4-Methylenedioxymethamphetamine (MDMA, ecstasy) misuse is associated with hyponatremia particularly in women. Hyponatremia is possibly due to inappropriate secretion of plasma arginine vasopressin (AVP). Objective: To assess whether MDMA increases plasma AVP and copeptin in healthy male and female subjects and whether effects depend on MDMA-induced release of serotonin...

Sensitization to MDMA locomotor effects and changes in the functionality of 5-HT2A and D2 receptors in mice

Behavioural Pharmacology June 29, 2011 María José Varela, José Brea, Marı́a Isabel Loza et al. 18 citations

The behavioral and neurochemical adaptations related to chronic 3,4-methylenedioxymethamphetamine (MDMA) treatment are largely unknown. In this study, we assessed whether repeated administration of MDMA would induce (a) context-dependent locomotor sensitization in mice and (b) changes in serotonin 5-HT(2A) and dopamine D₂ receptor functionality as measured by [³⁵S]GTPγS binding. Mice were...
