Detailed Description

CONTEXT: No pharmacotherapies have been shown to increase long-term (≥ 6 month) tobacco abstinence rates among smokeless tobacco (ST) users, although bupropion SR has demonstrated potential efficacy in pilot studies.

OBJECTIVE: To determine the efficacy and safety of bupropion SR for tobacco abstinence among ST users compared with placebo.

DESIGN, SETTING, AND PARTICIPANTS: A randomized, double-blind, placebo-controlled trial conducted between August 2003 to May 2005 at two research centers with a 12-week treatment period and follow-up of smoking status to week 52.

INTERVENTION: Bupropion SR titrated to 150 mg twice daily or placebo for 12 weeks plus weekly behavioral interventions.

Main Outcome Measures: The primary endpoint was 7-day point-prevalence tobacco abstinence rate at week 12. Secondary outcomes included the prolonged and continuous tobacco abstinence rates at weeks 12, 24, and 52.
