From SNPedia

Zyban is the brand name for drug bupropion when prescribed to aid individuals stopping smoking.

SNPs in the region of the DRD2 gene have been studied in terms of their impact on the efficacy of the use of bupropion. In particular, rs1800497 may strongly influence whether Zyban helps a person stop smoking.

The newest competitor to Zyban is Chantix, the trade name for varenicline. No SNPs are known at this time to influence the efficacy of Chantix.
