A Double-Blind, Placebo-Controlled Trial of the Effectiveness of Memantine in Treating Cocaine Dependence

New York State Psychiatric Institute·interventional·Posted Aug 25, 2005·Updated Apr 24, 2019

In Brief

A Phase 2 clinical trial evaluating Memantine and placebo for Cocaine-Related Disorders. Completed, enrolled 81 participants across 1 site.

Detailed Summary

Cocaine is one of the most widely abused drugs in the United States. Memantine is a type of drug called an NMDA receptor antagonist. It works by decreasing normal excitement in the brain. NMDA receptor antagonists have shown to reduce cocaine-induced dopamine release in animal models, as well as lessen conditioned cocaine cues. The purpose of this study is to determine the effectiveness of memantine in preventing relapse to cocaine use in cocaine dependent individuals. In addition, this study will determine whether memantine produces better results than a placebo in decreasing cocaine craving, psychological symptoms, functional impairment, and discontinuation of treatment in cocaine dependent individuals.
