Bupropion/zonisamide

Bupropion/zonisamide (former tentative brand name Empatic, Excalia) is an experimental combination of bupropion which was under development for the treatment of obesity.[1][2][3] Bupropion is a norepinephrine–dopamine reuptake inhibitor and nicotinic acetylcholine receptor antagonist, while zonisamide is an anticonvulsant acting as a sodium channel blocker, T-type calcium channel blocker, and weak carbonic anhydrase inhibitor.[1] The combination was being developed by Orexigen Therapeutics and reached phase II clinical trials prior to discontinuation.[1][4][5]
