    Abstract:
    The effects of the 5HT1A agonist 8-hydroxy-2-(di-n-propylamino)-tetralin (8-OH-DPAT) were investigated on food intake in non-deprived mice. 8-OH-DPAT (50-200 mg/kg) administered subcutaneously (s.c.) 5 min prior to presentation of food, produced a dose-related increase in cumulative food intake in C57BC6 mice. The hyperphagic effect of 8-OH-DPAT (100 mg/kg, s.c.) was abolished by concurrent treatment with the 5HT1A receptor antagonist N-[2-(4-2-methoxyphenyl)-1-piperazinyl]-N-(2-pyridyl) cyclohexanecarboxamide (WAY100635; 0.3 mg/kg, s.c.). These data show that 8-OH-DPAT produces an increase in food consumption in non-deprived mice by a 5-HT1A receptor-mediated mechanism of action.
