The purpose of this study is to determinate the effect of a pre-treatment with carvedilol, a alpha- and beta-adrenergic receptor blocker, on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, “Ecstasy”). The investigators hypothesize that carvedilol will attenuate the cardiovascular and subjective response to MDMA.

Effects of MDMA alone and after pretreatment with reboxetine, duloxetine, clonidine, carvedilol, and doxazosin on pupillary light reflexThis study analysed data from five separate clinical trials (n=80) that explored the effects of MDMA on pupillary light reflex and the effects following pretreatment with reboxetine, duloxetine, clonidine, carvedilol, and doxazosin, respectively. MDMA produced mydriasis, prolonged the latency, reduced the response to light and shortened the recovery time and this impairment returned to normal 6 hours post-treatment. Only reboxetine and duloxetine interacted with the effects of MDMA on pupillary function.
