Sensitive high-performance liquid chromatographic method with fluorescence detection for measurement of vinorelbine
1Laboratorio di Farmacologia Clinica, Centro di Riferimento Oncologico, Aviano, Italy.
Abstract:
A high-performance liquid chromatographic (HPLC) method with fluorescence detection for the determination of vinorelbine in plasma is described. The technique was derived from that published by Debal for an assay of vinorelbine in cell culture medium. The modifications concern the preparation procedure for plasma samples (a two-step liquid-liquid extraction from plasma is described), optimization of the mobile phase composition, and use of a single C18 column. These changes resulted in an improved sensitivity and reproducibility of the assay and led to its feasibility for clinical pharmacokinetic studies. The range of the assay is 2 to 1000 ng/ml.
