Lupitidine (INN; lupitidine hydrochloride (USAN); development code SKF-93479) is a long-acting H2 receptor antagonist[1] developed by Smith, Kline & French and described as an antiulcerogenic that was never marketed.[2] It was shown to inhibit nocturnal gastric acid secretion[3] and, in experiments on rodents, produced diffuse neuroendocrine cell hyperplasia and an increase in multifocal glandular hyperplasia due to hypergastrinemia resulting from the pharmacological suppression of gastric acid secretion.[4]
