The proposed study will assess the efficacy of moclobemide, a selective, reversible MAO-A inhibitor, in facilitating smoking cessation in treatment-seeking female smokers. This rationale is based on several findings from previous work: 1) cigarette smoke contains constituents that inhibit both forms of the enzyme monoamine oxidase (MAO-A and MAO-B); 2) that severity of depression symptoms after smoking abstinence is correlated with the level of MAO-A inhibition previously obtained from smoking; 3) moclobemide, an MAO-A inhibitor was found efficacious in a smoking cessation treatment trial (Berlin et al., 1995); and 4) women show a greater association between smoking and depression than men and women smokers in our previous trials report smoking to alleviate symptoms of depression to a greater extent than men.

---|---|---|---|---|
Other | Safety of Moclobemide + Nicotine Patch | Safety of the moclobemide + nicotine patch treatment will be assessed by tabulating the number of participants rating side effects > "moderate". | 1, 2, 4, 7 and 11 weeks after starting Moclobemide + Nicotine Patch | |
Other | Tolerability of Moclobemide + Nicotine Patch | Tolerability of the moclobemide + nicotine patch treatment will be assessed by tabulating the number of participants requiring dose reductions (or discontinuation of medication). | 1, 2, 4, 7 and 11 weeks after starting Moclobemide + Nicotine Patch | |
Primary | Continuous Four-week Abstinence From Smoking | Number of participants who reported continuous four-week abstinence from smoking (weeks 6-10 post target quit date), confirmed by expired air carbon monoxide (CO). | Weeks 6-10 post quit day | |
Secondary | Point Abstinence From Smoking at Six Months Post Quit | Number of participants who reported 7-day point abstinence from smoking at six months post quit, confirmed by expired air CO. | 7 day point abstinence from smoking at six months post quit | |
Secondary | Continuous Ten Week Abstinence From Smoking | Number of participants who reported continuous ten-week abstinence from smoking (weeks 1-10 post quit day), confirmed by expired air CO. | 10 weeks post quit day | |
Secondary | Percentage of Change in Smoking Withdrawal Symptoms | Withdrawal symptoms will be assessed by questionnaire on Quit Day, 1 week post quit, 3 weeks post quit, 6 weeks post quit,10 weeks post quit and 6 months post quit (if applicable) using the Shiffman-Jarvik questionnaire, which consists of 33-items rated from 1 to 7, where 1= not at all, 2= very little, 3= a little, 4= moderately, 5= a lot, 6= quite a lot, and 7= extremely. The 33 items are grouped into 8 subscales: Craving, Negative Affect, Appetite, Arousal, Somatic - Anxiety, Somatic - G.I., Somatic - Respiratory Tract, and Habit Withdrawal. The range of scores for each subscale will be 1-7, with higher scores indicating more of the withdrawal symptom having been experienced. | Quit day and 1 week, 3 weeks, 6 weeks, 10 weeks and 6 months post quit day | |
Secondary | Percentage of Change in Expired Air Carbon Monoxide (CO) During the First Week of Nicotine Patch Treatment. | The initial response to nicotine patch will be assessed by looking at the percent change in expired air carbon monoxide (CO) at the end of week one (Study Visit 2) relative to baseline (Study Visit 1). | Baseline and 1 week |
