title: Comparison of the satiating effect of the CCKA receptor agonist A71378 with CCK-8S.
abstract: The satiating effect of the selective cholecystokininA (CCKA) receptor agonist A71378 and the mixed A and B receptor agonist CCK-8S were compared in 24-h food-deprived rats. After systemic application of 1.6, 8.0, and 40 micrograms/kg A71378 or CCK-8S, respectively, food intake was measured for 24 h. During the first hour A71378 and CCK-8S decreased food intake similarly. Two and 4 h after treatment, the satiating effect of A71378 continued. In contrast, 2 h after administration of CCK-8S a slight effect was observed at the highest dose (40 micrograms/kg), which totally disappeared after 4 h. In summary, the effect of A71378 on food intake is longer lasting compared to CCK-8S.
