A multicenter trial of bupropion for cocaine dependence in methadone-maintained patients.
We conducted a multi-site, placebo-controlled, randomized double-blind clinical trial comparing bupropion HCL (300 mg/day) to placebo for the treatment of cocaine dependence in methadone-maintained subjects. A total of 149 subjects at three sites participated in a 12-week study. Outcome measures included cocaine use, level of depression, and psychosocial functioning. Results showed no significant differences between placebo and bupropion. Exploratory analyses suggested a medication effect for the subset of subjects depressed at study entry. The need to target subgroups of cocaine abusers in future pharmacotherapy trials and the possible role of treatment readiness are discussed.
