OBJECTIVE： To develop the method for the determination of lamotrigine in human plasma. METHODS： RP-HPLC was adopted. The samples were extracted by direct protein precipitation using naproxen as internal standard. XTerra RP18 column was used with the mobile phase consisted of methanol-0.01 mol .L^-1 potassium dihydrogen phosphate buffer（pH 6.0）（66：34）. The flow rate was 1.0 mL. min-~, and the detection wavelength was set at 280 nm. RESULTS： The linear range of lamotrigine was 0.5~32.0 mg-L-t（r=0.999 9）. The lowest detection concentration was 0.2 mg-L-~. The extraction recovery was 68.20%~82.35% and the method recovery was 99.03% ~103.21%. The RSD of intra-day and inter-day were both below 4.00%. CONCLUSION： The method is simple, sensitive and reproducible for concentration determination of lamotrigine in human plasma
