Aims To examine the effectiveness of transdermal selegiline for producing cigarette smoking abstinence.
Design Adult smokers were randomly assigned to receive selegiline transdermal system (STS) or placebo given for 8 weeks. All participants received cognitive behavior therapy (CBT). Follow‐ups were conducted at 25 and 52 weeks.
Setting Community smoking cessation clinic.
Participants 243 adult smokers (≥18 years of age; ≥10 cigarettes/day).
Measures Expired‐air carbon monoxide confirmed 7‐day point prevalence abstinence.
Findings STS was not superior to placebo. More women than men were abstinent at 52 week follow‐up (28% vs 16%, P < 0.05). Behavioral activation (BAS) moderated treatment response (P = 0.01). The survival rate through week 52 for those with high ‘drive’ scores on the BAS was 47% if assigned to selegiline and 34% if assigned to placebo. The survival rate for those with low ‘drive scores’ on the BAS was 35% if assigned to selegiline compared to 53% if assigned to placebo.
Conclusion Transdermal selegiline does not appear generally effective in aiding smoking cessation though there may be a selective effect in those smokers with low ‘behavioral activation’.
