Patients with reflux esophagitis suffer from a chronic condition that may cause considerable discomfort because of recurrent symptoms and diminished quality of life. This study was designed to evaluate acute and long-term treatment comparing standard doses of omeprazole and high-dose ranitidine.
Patients with endoscopically verified symptomatic esophagitis grade I or II were initially treated with omeprazole 20 mg daily or ranitidine 300 mg twice daily for 4-8 wk. Patients who were symptom free were randomized to maintenance treatment with omeprazole 10 mg daily or ranitidine 150 mg twice daily. Patients were seen every 3 months or at symptomatic relapse.
The percentage of asymptomatic patients after 4 and 8 wk treatment were 61% and 74%, respectively, for omeprazole and 31% and 50%, respectively, for ranitidine. Of 446 patients treated initially, 277 were asymptomatic, of whom 263 entered the maintenance study. The estimated proportion of patients in remission after 12 months of maintenance treatment with omeprazole 10 mg daily (n = 134) and ranitidine 150 mg twice daily (n = 129) were 68% and 39%, respectively (p < 0.0001).
Omeprazole 20 mg daily is superior to high-dose ranitidine in the symptomatic treatment of reflux esophagitis grade I and II. Furthermore, omeprazole at half the standard dose is more effective than ranitidine in a standard dose in keeping patients in remission for a period of 12 months.
反流性食管炎患者患有慢性疾病,由于症状反复出现和生活质量下降,可能会导致相当大的不适。本研究旨在评估比较标准剂量奥美拉唑和高剂量雷尼替丁的急性和长期治疗效果。
经内镜证实为I级或II级症状性食管炎的患者,最初接受每日20mg奥美拉唑或每日两次300mg雷尼替丁治疗4 - 8周。无症状的患者被随机分配接受每日10mg奥美拉唑或每日两次150mg雷尼替丁的维持治疗。每3个月或症状复发时对患者进行检查。
治疗4周和8周后,奥美拉唑组无症状患者的百分比分别为61%和74%,雷尼替丁组分别为31%和50%。在最初治疗的446例患者中,277例无症状,其中263例进入维持治疗研究。每日10mg奥美拉唑(n = 134)和每日两次150mg雷尼替丁(n = 129)维持治疗12个月后,估计缓解患者的比例分别为68%和39%(p < 0.0001)。
每日20mg奥美拉唑在I级和II级反流性食管炎的症状治疗方面优于高剂量雷尼替丁。此外,标准剂量一半的奥美拉唑在使患者缓解12个月方面比标准剂量雷尼替丁更有效。
