Abstract
Previous studies have produced conflicting results concerning the effect of chronic oral vs. parenteral (i.p.) clozapine administration on dopamine (DA) release and metabolism in the striatum and nucleus accumbens (n. accumbens) of freely moving rats using in vivo microdialysis. In this study, parenteral chronic clozapine (20 mg/kg/day for 21 days, i.p.) had no effect on basal DA release and metabolism in either region. Chronic treatment with parenteral clozapine also did not reverse the decrease in DA release and metabolism in striatum and n. accumbens produced by apomorphine (100 μ/kg, s.c.). These results differ significantly from a previous report following i.p. clozapine and confirm the results previously reported with oral clozapine.
