Objectives: To compare the efficacy and frequency of adverse experiences of misoprostol and sucralfate in the prevention of gastric ulcers in patients receiving nonsteroidal anti-inflammatory drug (NSAID) therapy. Design: A prospective, randomized, single-blind, multicenter trial. Patients: Patients with osteoarthritis receiving treatment with ibuprofen, piroxicam, or naproxen and experiencing abdominal pain were eligible. Interventions: Patients who were expected to receive at least 3 months of NSAID therapy and who did not have a gastric ulcer at the time of the initial screening endoscopy were randomized to receive misoprostol, 200 μg four times a day, or sucralfate, 1 g four times a day. A gastric ulcer was defined as a lesion of the gastric mucosa 0.3 cm or greater in diameter. Patients were followed clinically, and repeat endoscopies were performed after 4, 8, and 12 weeks. Main Measurement: The development of a gastric ulcer, which was regarded as a prophylaxis failure. Results:Two hundred fifty-three patients were evaluable for efficacy analysis. A gastric ulcer developed in 2 of the 122 (1.6%, 95% Cl, 0.3% to 6.4%) patients on misoprostol, compared with 21 of 131 patients on sucralfate (16%, Cl, 10.4% to 23.7%). The difference in ulcer rates was 14.4% (Cl, 10.4% to 19.5%; P < 0.001). Conclusion: In patients receiving chronic NSAID therapy for osteoarthritis, treatment with misoprostol for 3 months was associated with a significantly lower frequency of gastric ulcer formation, compared with treatment with sucralfate (P < 0.001).
