NCT01465685

Brief Summary

This study compares the interactive emotional/subjective effects of single doses of 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") and methylphenidate, a dopamine (DA) and norepinephrine (NE) transporter blocker, in healthy subjects. The primary goal is to determine the role of transporter mediated DA and NE release in the subjective response to MDMA in humans. The investigators hypothesize that methylphenidate will attenuate the subjective response to MDMA.

Drug: 3,4-MethylenedioxymethamphetamineDrug: MethylphenidateDrug: Placebo

Interventions

125 mg per os, single dose

Also known as: MDMA, ecstasy
MDMA, methylphenidate, placebo

1 hour before MDMA/placebo 60 mg methylphenidate per os, single dose

Also known as: Ritalin, Concerta
MDMA, methylphenidate, placebo

capsules identical to MDMA or methylphenidate

MDMA, methylphenidate, placebo
