Rapid infusion with valproate sodium is well tolerated in patients with epilepsy.

Abstract

Many IV antiepileptic drugs administered in emergency situations to patients with prolonged seizures have serious adverse effects. For this reason, the authors conducted a multicenter, open-label, prospective, dose-escalation study of IV valproate sodium administered to patients with epilepsy at rates of infusion of up to 6 mg/kg/minute and doses of up to 30 mg/kg. Valproate sodium had no clinically significant negative effects on blood pressure and pulse rate and caused only mild-to-moderate, reversible adverse events.
