Ecstasy, 3,4-methylenedioxymetamphetamine (MDMA), is a recreational drug used among adolescents, including young pregnant women. MDMA passes the placental barrier and may therefore influence fetal development. The aim was to investigate the direct effect of MDMA on cortical cells using dissociated CNS cortex of rat embryos, E17. The primary culture was exposed to a single dose of MDMA and...
ABSTRACTDespite the great popularity of 3,4‐methylenedioxymethamphetamine (MDMA, Ecstasy) as a drug of abuse, not much is known about the detailed mechanisms of the acute and subchronic effects of the drug. There is especially a lack of information about the distinct behavioural effects of its optical isomers (enantiomers) R‐ and S‐MDMA compared with the racemic RS‐MDMA. For this purpose,...
3,4-Methylenedioxymethamphetamine (MDMA) is widely abused as a psychoactive recreational drug. It is well known that MDMA induces neurotoxic damage of serotonergic nerve endings. Although drug abuse is increasing among youths, it is unclear whether recreational drugs affect the development of nerve growth. Thus, the present study examined the effect of recreational drugs, such as MDMA,...
Abstract MDMA (3,4‐Methylenedioxymethamphetamine) is an amphetamine derivative widely used for recreational purposes. We have recently shown that repeated treatment with high doses of MDMA‐induced impairments in the acquisition and recall of an active avoidance task in mice. In this study, we examined whether the endogenous peroxisome proliferator‐activated receptor‐α (PPAR‐α) agonist,...
The use of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) has increased in recent years; it can lead to life-threatening hyperthermia and serotonin syndrome. Human and rodent males appear to be more sensitive to acute toxicity than are females. MDMA is metabolized to five main metabolites by the enzymes CYP1A2, CYP2D and COMT. Little is presently known about sex-dependent differences in the...
In despite the similarity of mechanisms of action between both selective serotonin reuptake inhibitors (SSRI) and MDMA (main compound of "Ecstasy") there are relatively few reports on the effects of the later on animal models of depression. There are many animal models designed to create or to assess depression. Mild chronic stress (MCS) is a procedure designed to create depression. MCS...
Ingestion of 3, 4-methylenedioxymethamphetamine (MDMA) leads to heightened response to sensory stimulation; thus, MDMA is referred to as "ecstasy" because it produces pleasurable enhancement of such sensation. There have been no electrophysiological studies that report the consequences of MDMA on sensory input. The present study was initiated to study the effects of acute and chronic MDMA on...
Background and purpose: 3,4-Methylenedioxymethamphetamine (MDMA) and cocaine are two widely abused psychostimulant drugs targeting the dopamine transporter (DAT). DAT availability regulates dopamine neurotransmission and uptake of MDMA-derived neurotoxic metabolites. We aimed to determine the effect of cocaine pre-exposure on the acute and long-term effects of MDMA in mice. Experimental...
The present paper outlines the results of analyses carried out on the content of tablets sold as ecstasy, collected in the Netherlands by the Drugs Information Monitoring System (DIMS) from January 1993 to December 2008. During a period of 16 years, the DIMS analysed the content of 33 006 tablets sold as ecstasy that were handed in by numerous individual (potential) substance users. The DIMS...
It has been suggested that activation of dopamine D1-like and D2-like receptors contribute equally to the maintenance of drug self-administration. This study compared the contribution of these receptor subtypes to 3,4-methylenedioxymethamphetamine (MDMA) and methamphetamine (MA) self-administration. Effects of pretreatment with the D2-like receptor antagonist, eticlopride (0.0, 0.0125, 0.025 or...
