Double-blind placebo-controlled trial of fluoxetine in smoking cessation treatment including nicotine patch and cognitive-behavioral group therapy

Abstract

Smoking cessation attempts are often complicated by dysphoria/depression, weight gain, craving, and other nicotine withdrawal symptoms. Fluoxetine's antidepressant and anorectant properties, along with its capacity to attenuate compulsive behavior, suggest that this medication might facilitate smoking cessation treatment. We examined the effect of fluoxetine on smoking cessation in the context of a program that included group cognitive-behavioral therapy (six weeks) and transdermal nicotine patch(ten weeks). In a double-blind randomized trial of fluoxetine for smoking cessation, 150 daily smokers were assigned to placebo (n=48), 20 mg (n=51), or 40 mg fluoxetine (n=51). Fluoxetine did not significantly improve smoking cessation rates, either for those with or without major depressive disorder(MDD)histories or elevated current depression. Our results suggest that fluoxetine may moderate withdrawal symptoms, even if that was not manifested in improved smoking cessation rates. Our results, however, clearly favor the use of fluoxetine if weight gain is a major clinical obstacle to smoking cessation.
