title: The treatment of "cimetidine resistant" peptic ulcers by ranitidine hydrochloride: a new histamine H2-receptor antagonist.
abstract: Twelve patients with endoscopically confirmed peptic ulcers which had failed to heal despite standard cimetidine therapy were treated with 300 mg ranitidine hydrochloride daily for 4 to 8 weeks. Nine patients had complete symptomatic relief although the ulcer was found to have healed endoscopically in only six. Two patients derived no benefit from treatment and in 1 patient symptoms continued despite ulcer healing. Ranitidine would appear, therefore, to be of benefit in some "cimetidine resistant" patients.
