Zyban: A Tobacco Cessation Aid

Zyban is a non-nicotine aid to help people who want to quit using tobacco. It was initially developed and marketed as an antidepressant (Wellbutrin [bupropion hydrochloride]). Zyban is chemically unrelated to tricyclic, tetracyclic, selective serotonin re-uptake inhibitor, or other known antidepressant agents. It is presumed to act on the dopaminergic and/or noradrenergic pathways involved in nicotine addiction and withdrawal.

Studies suggest that Zyban may be effective in helping people who want to stop using tobacco. Participating in a tobacco cessation program increases the chances of success.
