Plasma Valproate Concentration after Simultaneous Administration with Faropenem Sodium in Rats

The drug interaction between sodium valproate (VPA), an anticonvulsant, and faropenem sodium (FRPM), a new penem antibiotic drug, was studied in rats. No significant change was observed in the plasma VPA concentration when compared with the control after the administration of VPA (TOO mg/kg per oral) simultaneously with FRPM (600 mg/kg per oral).
