Bupropion, whose best known trade name is Wellbutrin, is an antidepressant that is believed to inhibit norepinephrine and dopamine reuptake. It is an atypical antidepressant because it does not have a tricyclic structure and is not a selective serotonin reuptake inhibitor. Bupropion is also used as an aid to stop smoking and to combat anxiety, sexual dysfunction, and obesity. [Taken from Wikipedia—Ed.]
