Effects of dopaminergic and serotonergic drugs on ethanol-induced hypothermia

Abstract:
The effects of dopaminergic and serotonergic drugs on ethanol-induced hypothermia were studied in the rat. Pretreatment with haloperidol attenuated the hypothermia in a dose-dependent manner. Apomorphine produced a dose-dependent effect on the hypothermia. At a dose of 2.0 mg/kg, apomorphine potentiated ethanol-induced hypothermia, whereas at 0.1 mg/kg, it produced a delayed attenuation effect between 30 min and 45 min after its injection. The former effect was blocked by haloperidol, whereas the latter was not affected by haloperidol, but blocked by pretreatment with parachlorophenylalanine. It is concluded that both dopamine and serotonin exert modulatory effects on ethanol-induced hypothermia.
