Background: Rates of smoking in East Asian men range from >35% to >60%, and are increasing in women and the young.Objective: This study evaluated the efficacy and tolerability of 1 mg BID varenicline, a novel alpha(4)beta(2) nicotinic acetylcholine receptor partial agonist, for smoking cessation in smokers in Taiwan and Korea.Methods: A randomized, double-blind, placebo-controlled, 12-week treatment, 12-week follow-up trial was conducted at 5 sites each in Korea and Taiwan. Eligible subjects, smoking >= 10 cigarettes/d, received brief smoking-cessation counseling and were randomly assigned in a 1:1 ratio to varenicline 1 mg BID (titrated during the first week) or placebo. Smoking status was established by self-report and confirmed at clinic visits by end-expiratory carbon monoxide = 5% for varenicline were nausea (43.7% for varenicline vs 11.3% placebo), insomnia (15.1% vs 13.7%), increased appetite (7.9% vs 6.5%), constipation (7.1% vs 2.4%), anxiety (5.6% vs 2.4%), and abnormal dreams (5.6% vs 0.8%).
