Proglumide has been studied for its ability to inhibit gastric secretion and to protect the gastroduodenal mucosa against the injuries caused by pyloric ligation, hypothermic restraint stress, acetic acid, nonsteroid anti-inflammatory drugs, reserpine, cysteamine and the cytodestructing agents: 80% ethanol, 0.6 M HCl, 0.2 M NaOH, 25% NaCl and 30 mg of acetylsalicylic acid in 0.35 M HCl in rats. The results of this study demonstrate that proglumide has both prophylactic and curative effects on various experimentally induced ulcers. It produced a dose-dependent inhibition of gastric secretion in the pylorus-ligated rats and reduced significantly the intensity of gastric lesions induced by pyloric ligation, hypothermic restraint stress, acetic acid, mucosal damaging agents and that of duodenal ulcers induced by cysteamine. The intensity of gastric lesions induced by nonsteroid anti-inflammatory drugs and reserpine was also reduced significantly by proglumide. Cimetidine, which was used as a standard antiulcer drug for comparison, also produced a similar protective effect in most of the models used by us. It was found to have a more potent antisecretory effect but failed to protect the rats against the gastric mucosal damage induced by hyperthermic restraint stress and 0.2 M NaOH. Our findings suggest that proglumide exerts these antiulcer effects by its antisecretory, gastric mucosal resistance increasing and cytoprotective activities. Further studies are required to find out its exact mechanism of action and therapeutic usefulness.
