The ability of a cholecystokinin antagonist Proglumide to inhibit satiety induced by intraperitoneal injections of cholecystokinin octapeptide (CCK-OP) and bombesin was examined in rats equipped with chronic gastric cannulae. Both CCK-OP and bombesin significantly suppressed sham feeding. Proglumide administered alone did not alter sham feeding but it abolished the suppression of feeding induced by CCK-OP. In contrast. Proglumide did not inhibit the effect of a low dose of bombesin, but partially inhibited satiety induced by a high dose of bombesin, thus confirming our previous findings. These results indicate that the effect of Proglumide is independent of its recently described effects on gastric emptying in rat. © 1984.
