Official title

Bupropion-Enhanced CM for Cocaine Dependence

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This project will examine effects of bupropion extended release (XL) at a dose of 300mg/day for cocaine abstinence among persons receiving methadone for the treatment of opioid use disorder. Participants also earned financial incentives for providing urine samples that tested negative for cocaine. Bupropion was examined for this purpose because of its previously demonstrated efficacy and safety as well as its pharmacological actions at dopamine systems. Participants were randomly assigned to bupropion XL vs. placebo and received different incentive schedules depending on whether they demonstrated abstinence from cocaine early in the study. Outcomes were tracked over a 6-month time frame and the overarching hypothesis was that bupropion (as compared to placebo) would increase the number of urine samples testing negative for cocaine, independent of whether participants demonstrated abstinence from cocaine early in the study.
