Varenicline addresses gender gap in smoking cessation rates for women

Ordinarily, women have poorer smoking quit rates than men but a new analysis of data shows that the drug varenicline could tackle this issue.

Female smokers are more vulnerable than men to the serious health outcomes of smoking. But women are less successful than men at quitting

Women who smoke are more vulnerable than men to the serious health outcomes of smoking, and women are less successful than men at quitting.

The drug varenicline (Chantix) reduces tobacco craving, withdrawal symptoms and the reinforcing effects of smoking. So researchers at Yale University investigated whether the efficacy of the drug is different for women compared with men. After 12 weeks of varenicline treatment, the odds of women quitting had increased 4.95 times, compared with 3.42 times for men, according to a meta-analysis of 6,710 smokers (34% female) from 16 randomised, double-blind, placebo-controlled studies[1]
.

Varenicline was equally effective in women and men at one-year follow-up, and the researchers considered it especially important for addressing gender differences often seen in smoking cessation rates.
