OBJECTIVE: The purpose of this study was to evaluate the efficacy of long-term use of bupropion sustained release (SR), the nicotine patch, and the combination of these 2 treatments in patients who initially failed treatment. METHODS: This was a post hoc analysis of a multicenter, double-blind, randomized, placebo-controlled clinical trial in 893 smokers. Patients were randomly assigned to 9 weeks of treatment with placebo (n = 160), bupropion SR (n = 244), nicotine patch (n = 244), or a combination of nicotine patch and bupropion SR (n = 245). The study was originally designed with a follow-up period of 52 weeks. In this analysis, short-term success was defined as smoking cessation after 14 or 21 days of therapy and long-term success was defined as smoking cessation after >21 days of therapy. Patients who did not achieve short-term success were evaluated for long-term success at week 9 (end of treatment), 6 months, and 1 year after the start of the study. RESULTS: The mean age of the smokers was 44 years. The majority (93%) of patients were white, and 52% were female. The study subjects smoked an average of 27 cigarettes per day. Among the 467 patients who initially failed treatment in the first 3 weeks, treatment withbupropion SR alone and in combination with the nicotine patch produced significant increases in successful smoking cessation rates from weeks 4 to 9 (19% bupropion SR or combination, 7% nicotine patch, 7% placebo), at month 6 (11% bupropion SR, 13% combination, 2% nicotine patch, 3% placebo), and at month 12 (10% bupropion SR, 7% combination, 2% nicotine patch, 1% placebo) (P < 0.05 for bupropion SR and combination vs nicotine patch or placebo). CONCLUSION: Among patients who initially failed treatment, continued therapy with bupropion SR, either alone or in combination with the nicotine patch, resulted in significantly higher short- and long-term smoking cessation rates than treatment with the nicotine patch alone or placebo.
