Double-blind comparison of carbamazepine and placebo for treatment of cocaine dependence.

Abstract

This study was conducted to determine the effectiveness of carbamazepine (CBZ) for treatment of cocaine dependence. Sixty-two (CBZ = 28, placebo = 34) cocaine-dependent (DSM-III-R criteria) volunteers consented to be treated for eight weeks with standardized outpatient individual counseling twice a week plus double-blind CBZ or inactive placebo. During the 8-week trial, both groups showed increased number of urine samples negative for cocaine, significantly (P < 0.01) decreased self-reported cocaine use (money spent and grams used), and decreased Beck Depression Inventory and Symptom Check List-90-Revised (SCL-90-R) total scores. However, there were no significant differences between CBZ and placebo. This study does not support the effectiveness of CBZ for outpatient treatment of cocaine dependence.
