In one clinical safety study, approximately 90 patients withepilepsyand with no measurable plasma levels of valproate were given single infusions of Leptil (up to 15 mg/kg and mean dose of 1184 mg) over 5-10 minutes (1.5-3.0 mg/kg/min). Patients generally tolerated the more rapid infusions well. This study was not designed to assess the effectiveness of these regimens.
