The investigators intend to find a way to reduce the titration period of lacosamide. Dosage of lacosamide is increased from 100-200 mg/d to 400 mg/d by three different titration schedule. Safety of lacosamide administration is primary endpoint. 50% responder rate (seizure reduction) and blood level of lacosamide are investigated for secondary endpoints.
Three different dose titration schedules are tested to find a way to reduce the titration period of lacosamide
