Injection of cholecystokinin (CCK) reduces food intake and delays gastric emptying. We have previously shown that endogenous CCK also reduces food intake. This may be achieved by a delay in gastric emptying. We investigated the role of CCK in gastric emptying by inhibiting the actions of CCK released by a meal, using a CCK antagonist, proglumide. We postulated that inhibition of CCK should induce an increase in gastric emptying. Gastric emptying was determined in rats by a marker dilution technique using direct gastric intubation. Proglumide (150 mg/kg) significantly accelerated emptying of liquid food by 12.8% (P less than 0.005, n = 12) when injected intraperitoneally following a food preload. Proglumide injected before feeding was ineffective. Oral proglumide, which inhibited gastrin-stimulated acid secretion, was also ineffective. We concluded that proglumide increased gastric emptying by acting on a factor released by the preload, and since proglumide is a specific antagonist, this factor was probably CCK. Therefore CCK may play a physiological role in the regulation of gastric emptying.
