Interaction Between Duloxetine and 3,4-Methylenedioxymethamphetamine (MDMA, Ecstasy)

The purpose of this study is to determinate the effect of a pre-treatment with the combined serotonin (5-HT) and norepinephrine (NE) transport blocker duloxetine on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, “Ecstasy”). The investigators hypothesize that duloxetine will attenuate the subjective and cardiovascular response to MDMA.

Sex differences in the effects of MDMA (ecstasy) on plasma copeptin in healthy subjects
This study used a randomized placebo-controlled crossover design to explore the sex differences in increased plasma arginine vasopressin (AVP) secretion following MDMA administration (125mg) in healthy subjects (8 male, 8 female). MDMA significantly elevated plasma copeptin levels at 60 min and at 120 min compared with placebo in women but not in men and MDMA tended to increase urine sodium levels and urine osmolality compared with placebo.

Effects of MDMA alone and after pretreatment with reboxetine, duloxetine, clonidine, carvedilol, and doxazosin on pupillary light reflex
This 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.

A large set of the trials in our database are sourced from ClinicalTrials.gov (CTG). We have modified these post to display the information in a more clear format or to correct spelling mistakes. Our database in actively updated and may show a different status (e.g. completed) if we have knowledge of this update (e.g. a published paper on the study) which isn't reflected yet on CTG.
