Buspirone use for smoking cessation.
The results of buspirone efficacy have been inconsistent and contradictory. The rate of smoking abstinence has been reported to range from 36% to 88% and 16% to 89% in buspirone and placebo treatment groups, respectively. Only one controlled study reported buspirone efficacy in reducing nicotine withdrawal symptoms, although it was based on a small sample population and only 4 weeks of follow-up. The most recent studies have been unable to demonstrate the efficacy of buspirone in smoking cessation or in the relief of withdrawal symptoms. A placebo-controlled, randomized trial with a large number of patients, relatively high doses of buspirone (30-60 mg/d), strict abstinence criteria, long-term follow-up, and the inclusion of smokers with general anxiety or anxiety reported in previous quit attempts is needed to further evaluate buspirone efficacy in smoking cessation and the reduction of nicotine withdrawal symptoms. The treatment effects of buspirone could then be specifically tested as a function of alleviating the anxiety component of the smoking withdrawal syndrome. Finally, buspirone may prove to be an alternative in patients unsuccessful with or unable to tolerate transdermal nicotine therapy. How buspirone compares with bupropion therapy for smoking cessation is also unknown.
