title: Fenfluramine antagonizes the stimulation of food intake induced by the putative 5-hydroxytryptamine1A agonist, isapirone, in non-fasted rats.
abstract: Isapirone, a 5-hydroxytryptamine1A receptor agonist, stimulated food intake in non-fasted rats in a dose-dependent manner (1, 3 and 10 mg kg-1 s.c.). Fenfluramine, an antiobesity agent and a 5-HT releaser, at 3 and 10 mg kg-1 s.c. antagonized the isapirone-induced (3 mg kg-1 s.c.) feeding. These results are consistent with the known inhibitory role of 5-HT in the control of food intake in rats.
