Sufotidine (INN,[1] USAN, codenamed AH25352) is a long-acting competitive H2 receptor antagonist which was under development as an antiulcerant by Glaxo (now GlaxoSmithKline).[2] It was planned to be a follow-up compound to ranitidine (Zantac).[3] When taken in doses of 600 mg twice daily it induced virtually 24-hour gastric anacidity[4] thus closely resembling the antisecretory effect of the proton pump inhibitor omeprazole.[5] Its development was terminated in 1989[6] from phase III clinical trials based on the appearance of carcinoid tumors in long-term toxicity testing in rodents.[7]
