Similar effects of clozapine and olanzapine on ethanol-induced ascorbic acid release in the prefrontal cortex of freely moving mice
Previous studies have shown that acute systemic administration of ethanol induced ascorbic acid (AA) release in mouse striatum and prefrontal cortex. Clozapine and olanzapine showed similar effects on ethanol-induced AA release in mouse striatum. However, their effects on ethanol-induced
AA release in mouse prefrontal cortex have not been reported. Thus, their effects on this neurochemical event were further investigated in the present study. The results showed that ethanol (4.0 g/kg i.p.) significantly stimulated AA release in the prefrontal cortex by about 200% of
baseline in mice. Clozapine and olanzapine, at the dose of 1.0 mg/kg s.c., had no effect on basal AA or ethanol-induced AA release. However, both drugs, at the dose of 10 mg/kg s.c., significantly inhibited ethanol-induced AA release. The present study demonstrated for the first time that
similar actions were exhibited by clozapine and olanzapine for the regulation of ethanol-induced AA release in the mouse prefrontal cortex.
