AIM To investigate therapeutic effects of H 2 receptor antagonists (H 2A) and proton pump inhibitors (PPI) on peptic uleer bleeding. METHODS Thirty SD rats were randomly divided into 6 groups after gastric mucosal ulcer models were reproduced. The gastric mucosal bleeding time (GMBT) of the 5 groups was measured after the perfusion of ulcer site with pH 3.0, 4.0, 5.0, 6.0 and 7.0 buffer solution, respectively. Twenty four patients with peptic ulcer hemorrhage were randomly divided into 2 groups: during 24 hours, Losec one group received intravenous instillation of 40 mg Losec; Famotidine group 40 mg Famotidine. In each group, 24 hour intragastric pH was dynamically measured. In a retrospective study, the operation rate and mortality of bleeding gastric duodenal ulcer were compared between 272 patients (40 mg Famotidine intraveneously administered once daily) and 270 ones (40 mg Gaster intraveneously administered twice daily). RESULTS GMBT became significantly shorter with buffer solution at pH 6.0 or more than that at pH less than 6.0 ( P <0.05). The time when intragastric pH was over 4.0 or 6.0 in Losec one, was significantly longer than that in Famotidine ones, and the operation rate of bleeding gastrointestinal ulcer patients treated with Losec was statistically lower than that with Famotidine ( P <0.05). CONCLUSION Proton pump inhibitors have stronger anti acid secretory and therapeutic effects on gastrointestinal ulcer bleeding than H receptor antagonists.
