摘要

Sir: Varenicline, an (alpha)_4(beta)_2 nicotinic acetylcholine partial agonist, has been licensed in the United Kingdom (and approved in the United States) for the treatment of tobacco dependence since 2006. Studies have shown varenicline to result in higher smoking cessation rates over placebo, bupropion, and nicotine replacement therapy (NRT). In the one study conducted to date, varenicline was also seen to be effective in smokers with mental illness, there being no evidence of excess adverse events or exacerbation of preexisting conditions. Craving to smoke is the symptom most predictive of relapse in the period immediately following a cessation attempt. Varenicline appears to achieve improved efficacy by more effectively reducing craving than other therapies, while being similarly effective in reducing other tobacco withdrawal symptoms, such as depression, irritability, and poor concentration.
