This double-blind, placebo-controlled crossover trial (n=21) investigated whether memantine can mitigate memory impairment induced by MDMA in humans.
The study, conducted by the Universiteit Maastricht and supported by NWO, aimed to determine if memantine, when administered alongside MDMA, could have beneficial effects on memory. Additionally, the trial sought to understand the impact of MDMA on speech.
The research design involved a 4-way crossover, with subjects receiving combinations of memantine or placebo followed by MDMA or placebo, with a minimum two-week washout period between test days. The study required a total time investment of approximately 27 hours per subject, including medical screening and test days lasting around 6 hours each. Participants were required to abstain from caffeine, alcohol, and drugs during the study period. Eligible participants were recreational MDMA users aged between 18 and 40 years, with specific inclusion and exclusion criteria outlined.
The primary outcome measure was performance on memory tasks, with secondary outcomes including event-related potentials and speech recordings. The trial, approved by METC academisch ziekenhuis Maastricht/Universiteit Maastricht, was completed with 21 participants enrolled, starting in May 2011 and ending in January 2024.
