Abstract
Ro 22-6923, a synthetic trimethyl prostanoid, 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, nonsteroidal anti-inflammatory drugs (NSAIDs), reserpine, dimaprit, cysteamine and the cytodestructing agents--80% ethanol, 0.6 M HCl, 0.2 M NaOH, 25% NaCl, aspirin 30 mg in 0.35 M HCl and 100 mM sodium taurocholate in 0.2 M HCl. The results of this study demonstrate that Ro 22-6923 has both prophylactic and curative effects on various experimental models. It produces a dose dependent inhibition of the gastric mucosal damage induced by pyloric ligation, hypothermic restraint stress, NSAIDs, reserpine, dimaprit and cytodestructing agents and that of duodenal ulcers induced by cysteamine. It also produces a dose dependent healing of the acetic acid induced chronic gastric ulcers. These observations suggest that Ro 22-6923 exerts its anti-ulcer effects by its antisecretory, gastric mucosal resistance increasing and cytoprotective activities and that it may be a useful therapeutic agent for the treatment of peptic ulcer disease in humans.
