Preliminary study of buprenorphine and bupropion for opioid-dependent smokers

Abstract

In this double-blind, placebo-controlled trial, bupropion (BUPRO, 300 mg/day) was compared to placebo (PBO) for the concurrent treatment of opioid and tobacco addiction in 40 opioid-dependent smokers stabilized on buprenorphine (BUPRE, 24 mg/day). Participants received contingent, monetary reinforcement for abstinence from smoking, illicit opioids, and cocaine. Significant differences in treatment retention were observed (BUPRE+BUPRO, 58%; BUPRE+PBO, 90%). BUPRO treatment was not more effective than placebo for abstinence from tobacco, opioids, or cocaine in BUPRE-stabilized patients. These preliminary findings do not support the efficacy of BUPRO, in combination with BUPRE, for the concurrent treatment of opioid and tobacco addiction.

Panel A. Combined abstinence rates in the 10-week treatment period, adjusted for baseline CO-level as well as days of illicit opioid and cocaine use in the 30-days preceding enrollment. Panel B. Smoking abstinence rates in the 10-week treatment period, adjusted for baseline CO-level. Panel C. Illicit opioid abstinence rates in the 10-week treatment period, adjusted for days of illicit opioid use in the 30-days preceding enrollment. Panel D. Cocaine abstinence rates in the 10-week treatment period, adjusted for days of cocaine use in the 30-days preceding enrollment. Abstinence rates differed as function of biweek, p<.001 and medication × biweek. p = .0259.
