The effects of sodium valproate and its metabolites (5-OH-VPA and 4-OH-VPA) on electroconvulsions in rats.

Abstract

Effects of sodium valproate (VPA) and the omega-oxidation metabolites (5-OH-VPA and 4-OH-VPA) on the electroconvulsions in rats were analyzed. The drug (100 and 200 mg/kg/day) revealed marked dose-related anticonvulsant effect which manifested themselves by shortening the convulsions time and their intensity. The anticonvulsant effect of the omega-oxidation (50, 100 and 200 mg/kg/day) were weaker compared with the parent drugs.
