Efficacy of Varenicline in Methadone-Stabilized Cocaine Users
In Brief
A clinical study evaluating Varenicline and Sugar pill or Placebo for Cocaine Dependence and Nicotine Dependence. Completed, enrolled 31 participants across 1 site.
Detailed Summary
Cocaine addiction continues to be an important public health problem in the US with a significant cost to the individual and society. Among substance abusers, cocaine use has been recognized as a significant problem especially in methadone-maintenance patients. In several studies, rates of cocaine use have been reported to range from 30 to over 60 percent of those in methadone maintenance programs (Condelli et al. 1991; Hunt et al. 1984; Kidorf and Stitzer 1993; Kosten et al. 1988). In these patients, cocaine use seems to be a predictor of poor clinical outcome (Hartel et al. 1995; Kosten et al. 1987a). The development of effective pharmacotherapies for cocaine use disorders, especially in the opioid-dependent population is of great importance. Unfortunately, such effective pharmacotherapies do not exist. 1. To determine the safety and tolerability of varenicline in cocaine-using methadone-stabilized subjects. 2. To determine if varenicline is efficacious in reducing cocaine-use in methadone-stabilized subjects.
