The effects of nocloprost, nileprost, iloprost and (15 S)-15-methyl-PGE2 on gastric mucosal damage induced by stress, indomethacin and ethanol.
The preventive effects of nocloprost, nileprost, iloprost and (15S)-15-Methyl-prostaglandin E2 were studied in the rat gastric mucosal damage induced by restraint-cold stress, indomethacin and ethanol. Nocloprost was found to be the most potent orally active compound against rat mucosal damage induced by all noxious stimuli used in this study. Both nocloprost and iloprost were more effective on stress-induced ulcers than on those induced by indomethacin and ethanol. Nocloprost and 15-methyl prostaglandin E2 were also more active on ethanol-induced mucosal damage than on induced by indomethacin. No significant differences were obtained with iloprost and nileprost on indomethacin and ethanol-induced mucosal injury. These results indicate a more potent oral antiulcer activity of nocloprost.
