Bufenadrine (INNTooltip International Nonproprietary Name; developmental code name B.S. 6534), also known as 2-tert-butyldiphenhydramine, is a drug described as an antiemetic, antihistamine, anticholinergic, and antiparkinsonian agent which was never marketed.[1][2][3][4] It is the 2-tert-butyl analogue of diphenhydramine.[2] The drug was found to produce stereoselective hepatotoxicity in animals and this led to the discontinuation of its development.[2][5] Bufenadrine was first described in the literature by 1967.[1][4] Its INNTooltip International Nonproprietary Name suffix "-drine" is generally for sympathomimetics but bufenadrine itself is not actually a sympathomimetic or related agent.[6]
