Pharmacological interaction between 3,4-methylenedioxymethamphetamine (ecstasy) and paroxetine: pharmacological effects and pharmacokinetics.

Paroxetine inhibits acute effects of 3,4-methylenedioxymethamphetamine on the immune system in humans.

The effect of pretreatment with paroxetine on cell-mediated immune response and release of cytokines after the administration of 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") was investigated in a double-blind, randomized, crossover, controlled clinical trial in which 12 healthy male recreational users of MDMA participated. Subjects received 20 mg/day paroxetine (or placebo) for the 3 day...

Clinical Pharmacology of 3,4-Methylenedioxymethamphetamine (MDMA, “Ecstasy”): The Influence of Gender and Genetics (CYP2D6, COMT, 5-HTT)

UNLABELLED The synthetic psychostimulant MDMA (± 3,4-methylenedioxymethamphetamine, ecstasy) acts as an indirect serotonin, dopamine, and norepinephrine agonist and as a mechanism-based inhibitor of the cytochrome P-450 2D6 (CYP2D6). It has been suggested that women are more sensitive to MDMA effects than men but no clinical experimental studies have satisfactorily evaluated the factors contrib...

MDMA (3,4-Methylenedioxymethamphetamine) Analogues as Tools to Characterize MDMA-Like Effects: An Approach to Understand Entactogen Pharmacology

Besides stimulants and hallucinogens, whose psychotropic effects are shared by many structurally related molecules exhibiting different efficacies and potencies in humans, the phenylisopropylamine MDMA (3,4-methylenedioxymethamphetamine, XTC, "Ecstasy") is the prototypical representative of a separate class of psychotropic substance, able to elicit the so-called entactogenic syndrome in healthy...

Ambient Temperature Effects on 3,4-methylenedioxymethamphetamine (MDMA)-induced Thermodysregulation and Pharmacokinetics in Male Monkeys

Blockade of a resting potassium channel and modulation of synaptic transmission by ecstasy in the hippocampus.

3,4-Methylenedioxymethamphetamine (ecstasy, MDMA) and related amphetamines are CNS stimulants that have euphoric, memory-enhancing and neurotoxic properties. When applied in pharmacological doses to cultured rat hippocampal neurons, ecstasy reduced the conductance of a 50-pS barium-sensitive resting K+ channel and increased neuronal excitability. Ecstasy enhanced synaptic strength by irreversib...
