title: [Treatment of gastric ulcer with ranitidine: comparison of a single 300 mg dose at night with 150 mg twice a day].
abstract: Twenty five patients with endoscopically diagnosed gastric ulcer, were randomly allocated to treatment with ranitidine 300 mg at night or ranitidine 150 mg twice daily. After six weeks, ulcer healing was observed in 7 out of 14 patients (50%) treated with ranitidine 300 mg nocte and in 7 out of 11 (63.6%) receiving 150 mg bid. Cumulative healing rates at 12 weeks were 64.2% and 81.8%, respectively. There was no statistically significant difference between these two groups. No adverse events were reported by any patient. Ranitidine 300 mg administered at night was effective and a safe regimen for the treatment of gastric ulcer.
