In studies, 44% of CHANTIX users were quit during weeks 9 to 12 of treatment (compared to 18% on sugar pill). CHANTIX also helped reduce the urge to smoke.
Helping Smokers Quit
CHANTIX has been proven to be more effective in helping smokers quit than Zyban® (bupropion hydrochloride). The average person in these smoking cessation studies had been a smoker for more than 24 years. The trials involved a mix of men and women who smoked an average of 10 or more cigarettes a day.
CHANTIX is proven to work. Learn about the study.
1,022 patients were enrolled in this study, and results were duplicated in another identically designed clinical trial.
Patients received either CHANTIX 1 mg twice a day, Zyban 150 mg twice a day, or sugar pills twice a day for 12 weeks. In addition to the pills, patients were given a booklet on quitting smoking and received brief counseling at each visit.
In weeks 9 through 12 in the study, the smoking status of each patient was checked, and the information was compared among the 3 groups. Patients were considered quit if they did not smoke a cigarette (not even a puff) or use other nicotine products for the final 4 weeks of treatment. CHANTIX was proven to be more effective than the sugar pill or Zyban.
