Effectiveness of Disulfiram for Treating Cocaine Dependence in Individuals With Different Dopamine Beta Hydroxylase (DBH) Genes

Baylor College of Medicine·interventional·Posted Sep 8, 2005·Updated Mar 15, 2017

In Brief

A Phase 2 clinical trial evaluating Disulfiram, Methadone, and 2 other interventions for Cocaine Dependence and Opioid Dependence. Completed, enrolled 93 participants across 1 site.

Detailed Summary

Previous research has shown that disulfiram, a medication sometimes used for treating alcoholism, discourages cocaine use among cocaine addicts who are undergoing methadone treatment. By blocking the enzyme dopamine beta hydroxylase (DBH), disulfiram increases levels of dopamine and produces an unpleasant sense of hyperstimulation and discomfort in cocaine users. This study will evaluate the effectiveness of disulfiram in preventing drug relapse among cocaine and opiate addicts with varying inherited levels of DBH.
