title: Prevention by bedtime cimetidine of duodenal-ulcer relapse.
abstract: 45 patients with healed duodenal ulcers completed a six-month double-blind trial to compare the effects of cimetidine and placebo on the prevention of duodenal-ulcer relapse. A single bedtime dose of cimetidine (800 mg) was given and ulcer relapse was assessed endoscopically at regular intervals. At the end of the six-month trial, 16 of the 21 (76%) cimetidine-treated patients remained ulcer-free compared with only 3 of the 24 (12.5%) placebo-treated patients. No untoward effects of this treatment were observed.
