title: A multicenter, double-blind, randomized, placebo-controlled comparison of nocturnal and twice-a-day famotidine in the treatment of active duodenal ulcer disease.
abstract: The efficacy and safety of famotidine, a potent new long-acting H2-receptor antagonist, was compared with placebo in a multicenter, double-blind, randomized, placebo-controlled study in the United States. A total of 384 patients with endoscopically proven acute duodenal ulcer disease were enrolled. Patients received either famotidine or a placebo. The patients receiving famotidine were treated with one of three dose regimens, 40 mg h.s., 40 mg b.i.d., or 20 mg b.i.d. Patients were reassessed by endoscopy at 2, 4, and 8 wk if ulcer healing had not occurred sooner. A diary was kept to record the duration and intensity of the day and night pain and the amount of Gelusil antacid (Parke-Davis, Morris Plains, N.J.) ingested. Three hundred sixty-three patients met the evaluation criteria. The results revealed a 4-wk healing rate of 70%, 75%, 67%, and 31% for the famotidine 40 mg h.s., 40 mg b.i.d., 20 mg b.i.d., and placebo groups, respectively. The 8-wk healing rates for the same respective groups were 83%, 82%, 82%, 45%. Ulcer pain and antacid consumption occurred less often in the famotidine groups. The clinical and laboratory safety profile of the famotidine groups was similar to that of the placebo group. Famotidine appears to be an effective and safe once-a-day therapy for the treatment of acute duodenal ulcer disease. The recommended dosage is 40 mg h.s.
