Twenty-seven patients with peptic ulcer (19 with duodenal ulcer (DU) and eight with gastric ulcer (GU] refractory to H2-antagonists were treated with 40 mg of omeprazole once daily for 4-8 weeks, depending on the rate of ulcer healing. Clinical assessment, endoscopy and laboratory tests were performed at entry, after 2 and after 4 weeks, and if unhealed, also after 8 weeks' treatment. Ten healed patients were given a maintenance therapy of omeprazole 20 mg daily for up to 12 months during which the patients returned for endoscopy, gastric biopsy and laboratory tests at 3-monthly intervals. The initial treatment healed 15 of 19 (79%) DU patients in 2 weeks and all DU patients by 4 weeks. Seven of eight (87%) GU patients healed in 4 weeks and only one required 8 weeks' treatment. Symptom relief was rapid, with most patients being symptom-free within the first day of treatment. Six patients received 12 months' continuous maintenance therapy, one patient 9 months and three patients 6 months' treatment. All patients remained in remission whilst on omeprazole therapy. No adverse events were reported throughout the study. There were no clinically significant changes in haematology or blood chemistry after healing or during the long-term treatment. Biopsy samples revealed no histological changes in the gastric mucosa at any stage. Omeprazole 40 mg therefore was found to produce rapid healing and symptom relief in Asian patients with H2-antagonist-resistant peptic ulcers. Maintenance therapy with omeprazole 20 mg daily was shown to be safe and effective in preventing recurrence of peptic ulceration.
