Ranitidine and duodenal ulceration: a short-term and maintenance study.

Forty-eight patients successfully completed a six-week, double blind, placebo controlled trial of ranitidine hydrochloride 200mg twice daily for active duodenal ulceration. Following endoscopy 68% of the patients taking ranitidine had healed, compared to 35% of those who were taking placebo. Nineteen of the patients who had not healed then took a further six weeks of open active treatment; of these, 14 were successfully treated. Thirty-one of the patients who had healed duodenal ulcers then took ranitidine hydrochloride 100mg at night as a maintenance treatment for one year: 71% remained endoscopically and symptomatically in remission. No serious side effects were encountered.

Prevention of duodenal ulcer relapse by cimetidine: a one-year double-blind trial.

Fifty-one patients with duodenal ulcer which was healed by a six-week course of cimetidine completed a one-year double-blind study to compare the effects of cimetidine and placebo on the prevention of ulcer relapse. Patients were allocated at random to receive either 400 mg of cimetidine twice daily or placebo. Ulcer relapse was assessed by regular clinical follow up and endoscopy. A total of six of the 24 cimetidine-treated patients (25%) suffered a relapse compared to 25 of the 27 of placebo-treated patients (92.6%). Out of this total number of relapses, asymptomatic relapse with ulceration discovered by routine endoscopy at six months or one year, occurred in three patients receiving cimetidine and eight patients receiving placebo. Cimetidine prevents recurrence in patients with duodenal ulcer disease.
