The aim of this study was to compare duodenal ulcer healing and symptom relief after two and four weeks treatment with omeprazole or cimetidine in groups of patients treated in general practice and as hospital out-patients. It was a randomised, double-blind, parallel group study with stratification for trial centre (hospital or GP). Endoscopy was performed at entry, after two weeks and, if unhealed at two weeks, after four weeks. All endoscopies were carried out in hospitals. In all, 189 patients were randomised (98 omeprazole, 91 cimetidine), 79 (42 per cent) of which by GPs, to either omeprazole 20 mg om (n = 41) or cimetidine 800 mg nocte (n = 38) for two to four weeks. After two weeks, ulcer healing occurred in 56 per cent (omeprazole) and 29 per cent (cimetidine) (p less than 0.05) of patients treated by GPs, and 67 per cent (omeprazole) and 36 per cent (cimetidine) (p less than 0.005) of those treated as hospital out-patients. Similar differences in healing rates were seen after four weeks. Omeprazole produces faster duodenal ulcer healing than cimetidine whether patients are treated as hospital out-patients or by GPs.
