摘要
A high-performance liquid chromatographic (HPLC) procedure for lamotrigine was developed and validated. Lamotrigine (LTG) and an internal standard were extracted from plasma using liquid-liquid extraction under alkaline conditions into an organic solvent. The method was linear in the range 0.78-46.95 mu mol/l, with a mean coefficient of correlation (r)greater than or equal to 0.99923. The limit of detection (LOD) and limit of quantification (LOQ) were 0.19 and 0.58 mu mol/l, respectively. Within- and between-run precision studies demonstrated C.V.<3% at all tested concentrations. LTG median recovery was 86.14%. Antiepileptic drugs tested did not interfere with the assay. The method showed to be appropriate for monitoring LTG in plasma samples. (C) 2000 Elsevier Science B.V.
