    Abstract

    Objective - To see whether omeprazole was superior to cimetidine in healing ulcers of the body of the stomach. Design - Double blind randomised parallel group study of omeprazole versus cimetidine for six weeks with assessment of healing at end of every second week. Setting - Outpatient referrals in 11 centres in Denmark. Patients - One hundred sixty one patients who satisfied the following criteria: age 18-79; one or more ulcers of body of stomach (that is, at or above the angulus) seen endoscopically within four days before study treatment; no H2 receptor antagonists taken within previous two weeks; no history of gastric surgery and no complications needing surgery; no concurrent treatment or disease that might confound assessment; oral contraception or an intrauterine device being used by women of childbearing age. Interventions - Omeprazole 30 mg daily (one capsule in the morning) or cimetidine 1 g daily (one 200 mg tablet thrice daily, two tablets at bedtime) for six weeks. Inactive capsules and tablets provided so that all patients took same number of capsules and tablets daily. Compliance monitored by pill counts. End point - Endoscopic evidence of accelerated healing of type I gastric ulcers after four weeks of omeprazole. Measurements and main results - Pain recorded on diary cards and patients assessed after two, four, and six weeks of treatment for clinical state and by endoscopy and biopsy and repeat laboratory tests. Twenty eight patients withdrawn during trial for violations of protocol. At two weeks healing rates were identical in the two treatment groups (omeprazole 41% (30/73 patients); cimetidine 41% (30/73). At four weeks cumulative healing rates were 77% (53/69 patients) in the omeprazole treatment group and 58% (41/71) in the cimetidine treatment group (95% confidence interval of difference between groups 4% to 34%). By six weeks the cumulative healing rates in the two treatent groups differed by only 6% (60/68 patients (88%) given omeprazole; 53/65 (82%) given cimetidine). Log rank analysis with ulcer size used as covariable showed a significant difference in healing times in favour of omeprazole. There was no difference in the occurrence of pain relief between the two treatment groups. No serious clinical or biochemical side effects of treatment were noted. Conclusions - Omeprazole 30 mg daily accelerates healing of ulcers in the body of the stomach as compared with cimetidine 1 g daily. This effect is more pronounced in ulcers greater than 12 mm diameter.
