Impact of desipramine or carbamazepine on patient retention in outpatient cocaine treatment: preliminary findings

Abstract

This is a preliminary report of a double-blind comparison of desipramine or carbamazepine to placebo among subjects participating in an outpatient cocaine treatment program. Sixty-five subjects were randomly assigned to one of the active drugs or placebo and followed until treatment completion or drop-out to determine if either drug enhanced retention in treatment and/or increased cocaine abstinence. There was no significant difference between carbamazepine or desipramine and placebo on either outcome measure in this preliminary analysis. While this is a preliminary report and does not take into account the heterogeneity of the patients in cocaine treatment, the results are consistent with those of other investigators and suggest that use of desipramine or carbamazepine may not offer any advantage in retaining cocaine-dependent patients in treatment.
