title: Comparative study of omeprazole and famotidine in the treatment of duodenal ulcer.
abstract: In a double blind, multicenter, parallel group clinical trial in patients with symptomatic duodenal ulcers, 129 patients were randomized to receive either omeprazole 20 mg once daily (n = 65) or famotidine 40 mg once daily (n = 64) for 2 weeks, and if the ulcers were not healed, for a total of 4 weeks. Seventy four percent of these receiving omeprazole had healed ulcers after 2 weeks compared with 34.3% of those receiving famotidine (p < 0.001). At 4 weeks, the respective figures were 97.3% and 77.6% (p < 0.001). After 2 weeks of treatment, only 11.1% and 29.8% of omeprazole and famotidine treated patients respectively had day time pain (p < 0.02). Diary cards (successfully completed by 2/3rd of patients) showed that omeprazole treated patients required smaller amounts of antacids (p = ns). Over the first two weeks, ulcer healing rate was similar in smokers and non- smokers. No significant side effects were reported in either group. Omeprazole 20 mg/day provides more rapid relief of symptoms and heals a greater proportion of duodenal ulcers at 2 and 4 weeks than famotidine 40 mg/day.
