Hypnotic action of flunitrazepam is reversed by proglumide in rats.
1. Caerulein, an analogue of cholecystokinin (CCK-8), like CCK-8, has been shown to produce hypnotic effects similar to those of benzodiazepine (flunitrazepam). 2. Proglumide antagonizes the action of CCK-8 and of its analogue. 3. The aim of the present study was to demonstrate whether proglumide would affect the potent hypnotic action of flunitrazepam in rats. 4. The association of proglumide with flunitrazepam suppress the increase of total sleep time and slow wave sleep seen after flunitrazepam alone. Proglumide alone has no effect on sleep stages. The authors report here for the first time that the hypnotic action of flunitrazepam is antagonized by proglumide in rat.
