Abstract:
:Clozapine (0.625-10.0 mg kg-1 s.c.), but not the two major clozapine metabolites, N-desmethylclozapine (0.625-10.0 mg kg-1 s.c.) or clozapine-N-oxide (0.625-10.0 mg kg-1 s.c.), caused a dose-dependent decrease in core temperature in the rat. Furthermore, the clozapine-induced hypothermia (2.5 mg kg-1 s.c.) was fully antagonised by pretreatment with the selective dopamine D1 receptor antagonist (+)-5-(2,3-dihydrobenzofuran-7-yl)-3-methyl-8-nitro-2,3,4, 5-tetrahydro-1 H-3-benzazepine-7-ol, maleate (NNC 687) (4.0 mg kg-1 s.c.). NNC 687 by itself (2.0-8.0 mg kg-1 s.c.) did not affect core temperature. The present results provide further evidence for the dopamine D1 receptor agonist properties of clozapine.
