Detailed description:
This is a prospective, double-blind placebo-controlled randomized pilot trial of the preliminary safety and efficacy of bupropion SR in combination with behavioral counseling for smoking cessation during pregnancy. A total of 150 pregnant smokers will receive medication (75) or placebo (75) for 12 weeks. Compassionate care/continuance of therapy will be available to pregnant subjects. Women who relapse to smoking postpartum will be offered an additional course of medication treatment. All subjects regardless of adherence with 12 week study drug administration period and smoking habits during pregnancy will be followed through the duration of their pregnancy, delivery, and 6-month postpartum period. Subject participation will begin between 13-30 wks of gestation and end 6 months postpartum. Participation will be ten (10) to thirteen(13) months in length.

Arms:
arm 1: Bupropion SR and smoking cessation counseling Subjects received Bupropion SR 150 mg tablet orally twice daily (BID) for 12 weeks. Subjects were instructed to begin using study medication (bupropion SR 150 mg orally for 3 days, then BID for 4 days) on study visit day 1, which was approximately 1 week prior to their quit date. Thereafter, they were continued to dose Bupropion SR 150 mg tablet orally BID for a total medication treatment of 12 full weeks.

Smoking cessation counseling included 35-minute counseling sessions at each of the first 2 visits and 10 minutes of smoking cessation counseling at subsequent visits, provided by the trained study nurse. arm 2: Placebo and smoking cessation counseling Subjects received matching Bupropion SR placebo tablet orally twice daily (BID) for 12 weeks. Subjects were instructed to begin using study medication (matched placebo tablets orally for 3 days, then BID for 4 days) on study visit day 1, which was approximately 1 week prior to their quit date. Thereafter, they were continued to dose matching Bupropion SR placebo tablet orally BID for a total medication treatment of 12 full weeks of therapy.
