    Abstract:
    In this double-blind, parallel-group multicenter study, patients with endoscopically proven gastric ulcers were randomly allocated to treatment with either 50 micrograms or 200 micrograms of misoprostol or 300 mg of cimetidine, each given four times daily for four weeks. Endoscopic, clinical and laboratory assessments were made before treatment and after four weeks; clinical and laboratory assessments were repeated at two weeks. In the Korean center, assessments were also made after six weeks and at eight weeks of treatment. Six hundred and thirty patients were studied. The three treatment groups were similar in age and occupation. However, the proportion of men in the misoprostol 50-micrograms, 200-micrograms and cimetidine 300-mg groups was 67%, 63%, and 59%, respectively. Therapeutic success was defined as complete healing of all ulcers, judged endoscopically. On an intent-to-treat basis, which includes all losses to follow-up and withdrawals as treatment failures, ulcer healing rates in the misoprostol 50-micrograms, 200-micrograms and cimetidine 300-mg groups were 39%, 51%, and 58%, respectively. In the Korean center, the healing rates were 38%, 64%, and 70%, respectively, after eight weeks of treatment. There was no statistically significant difference in the healing rates at four weeks between the misoprostol 200-micrograms and cimetidine 300-mg groups (P = 0.16). The healing rate with the misoprostol 200-micrograms dose was significantly better than with the 50-micrograms dose (P = 0.008). Cimetidine 300 mg relieved global pain significantly better than misoprostol 200 micrograms at two weeks (P = 0.047) but not at four weeks.(ABSTRACT TRUNCATED AT 250 WORDS)
