Cimetidine in bleeding peptic ulcer.
The effect of cimetidine on the risk of further bleeding shortly after acute gastrointestinal haemorrhage from peptic ulcer was investigated in a double-blind randomised trial. 34 patients were given cimetidine and 32 placebo, the two groups being matched for age, sex, and severity of haemorrhage. Further bleeding within a week of admission was detected clinically in 8 patients on cimetidine and 15 on placebo. Cimetidine had no effect on bleeding from duodenal ulcer, but only 2 of 14 patients with gastric ulcer treated with cimetidine bled again, compared with 10 of 19 patients on placebo. Cimetidine, therefore, may help to prevent haemorrhage from gastric ulcer but not duodenal ulcer.
