title: Treatment of active duodenal ulcers with famotidine. A double-blind comparison with ranitidine.
abstract: In a double-blind multicenter trial, 100 patients with active duodenal ulcer were treated with a single nocturnal dose of famotidine 40 mg or ranitidine 300 mg. Antacid tablets were allowed as additional treatment if needed for pain relief. Endoscopy was repeated after two weeks, and again after four weeks if the ulcer had not healed earlier. Two patients in the famotidine group were withdrawn from the study because of non-compliance with the protocol. After two weeks, ulcers in 64 percent of the patients receiving famotidine and 46 percent of the patients receiving ranitidine were healed (p = 0.072). After four weeks, healing rates were 94 percent (famotidine) and 90 percent (ranitidine). Pain relief was rapid in either treatment group, with a tendency for better response during the day in the famotidine group. Mean antacid consumption during the first week was 3.0 tablets (34.5 mmol) in the famotidine group and 4.1 tablets (47.2 mmol) in the ranitidine group. Famotidine provides excellent healing and relief of symptoms in patients with duodenal ulcer disease.
