The Efficacy and Safety of Low Dose Combination of LTG and VPA Compared to CBZ Monotherapy

To evaluate the efficacy of usual monotherapy and low dose combination of Lamotrigine and Valproate. Low dose combination may be more effective and tolerable because they are low dose and VPA reduce Lamotrigine metabolism.
