title: Ranitidine compared with cimetidine in the short-term healing of duodenal ulcer.
abstract: The efficacy of ranitidine (150 mg twice daily) and cimetidine (200 mg three times daily and 400 mg at night) in the short-term healing of duodenal ulcer has been assessed in a randomized controlled trial involving 106 patients. There were 3 drop-outs. Forty-two out of 53 patients (79%) treated with ranitidine had healed ulcers at 4 weeks compared with 37 out of 50 treated with cimetidine (74%). This difference is not significant. At 8 weeks the healing rate for ranitidine (98%) was significantly greater than that for cimetidine (86%) (P less than 0.05). There was no significant difference in healing rates between men and women and between smokers and non-smokers. Side effects were not a problem with either drug. There were no differences of clinical significance between laboratory values in the two treatment groups, although a minor increase in mean creatinine levels occurred in the cimetidine-treated group.
