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.
本研究旨在比较在普通诊所和医院门诊接受治疗的患者组中,使用奥美拉唑或西咪替丁治疗两周和四周后十二指肠溃疡的愈合情况及症状缓解情况。这是一项随机、双盲、平行组研究,按试验中心(医院或全科医生诊所)进行分层。在入组时、两周后以及如果两周时未愈合则在四周后进行内镜检查。所有内镜检查均在医院进行。共有189例患者被随机分组(98例使用奥美拉唑,91例使用西咪替丁),其中79例(42%)由全科医生随机分组,分别给予奥美拉唑20毫克每日一次(n = 41)或西咪替丁800毫克每晚一次(n = 38),治疗两至四周。两周后,全科医生治疗的患者中,56%(奥美拉唑组)和29%(西咪替丁组)(p < 0.05)的溃疡愈合,医院门诊患者中,67%(奥美拉唑组)和36%(西咪替丁组)(p < 0.005)的溃疡愈合。四周后观察到类似的愈合率差异。无论患者是在医院门诊接受治疗还是由全科医生治疗,奥美拉唑导致十二指肠溃疡愈合的速度都比西咪替丁快。
