Objective To evaluate the effecacy and safety of varenicline on smoking cessation intervention for patients with chronic obstructive pulmonary disease（COPD）. Methods 50 nicotine-dependent patients with COPD were divided into therapeutic and control groups.In a randomized,double-blind,placebo-controlled study,patients in the therapeutic group received varenicline 0.5～2.0 mg·d-1.Patients were followed up for 12 weeks after treatment. Results Week 9-12 CAR was significantly higher for varenicline（13） versus placebo（8）;CARs through 12 weeks post-treatment（weeks 9-24） were 8 with varenicline and 5 with placebo.The 7-day PP was 14 with varenicline versus 8 with placebo at week 12,and 9 versus 6 with placebo at week 24.Reports of depression,depressed mood,and depressive symptoms were similar for both treatment groups. Conclusion Varenicline is an efficacious and well tolerated pharmacologic treatment for smoking cessation among patients with mild moderate COPD.
