title: LC determination of indinavir in biological matrices with electrochemical detection.
abstract: A high performance liquid chromatographic (HPLC) method with electrochemical detection for the quantification of Indinavir in cell culture is described. The sample pre-treatment involved a protein precipitation procedure using acetonitrile. Chromatography was carried out on a base-deactivated reversed-phase column with an isocratic mobile phase. The method was validated with regard to specificity, linearity, limits of detection and quantitation, precision and accuracy, recovery and ruggedness. The proposed HPLC assay was utilised to directly evaluate the capability of P-glycoprotein expressing multidrug resistant cells in mediating the transport and efflux of protease inhibitor (PI) Indinavir, a basic compound in AIDS care.
