Non-nicotine pharmacotherapies for smoking cessation

Abstract

International chronic obstructive pulmonary disease guidelines recommend that smokers be strongly advised to quit, and should be offered help in doing so. The most effective smoking-cessation interventions combine behavioural support with pharmacotherapies. For smokers who do not wish to use nicotine replacement treatments, bupropion is a safe and effective non-nicotine alternative first-line treatment. Nortriptyline and clonidine have demonstrated efficacy in aiding smoking cessation, but are regarded as second-line therapies. A number of other non-nicotine treatments show promise, but more data are required before these can be recommended in assisting smokers to stop.
