Abstract
The arsenal of pharmacologic agents available for smoking cessation has expanded in the last few years, and it is likely to continue to do so. It is important that practicing physicians keep abreast of new methods as they become available and encourage patients who smoke to undertake cessation measures. Nicotine-replacement therapy is available in gum, patch, nasal spray, or inhaler form, and bupropion therapy aids in smoking cessation through dopaminergic activity. The foundation of effective intervention is likely to remain unchanged: an individualized plan addressing behavioral, addictive, pharmacologic, and relapse-prevention components. In addition to the necessary information about treatment choices, physicians should offer motivation, support, and follow-up to their patients who wish to quit smoking.
