摘要: A sensitive, specific, accurate and reproducible analytical method was developed validated for the quantitation of anticancer agent paclitaxel in human plasma. This procedure is based on high performance liquid chromatography/ion spray-tandem mass spectrometry. methodology highly specific because a MS/MS technique (multiple reactant-ion monitoring, MRM) used both its internal standard. The use fully automated solid phase extraction procedure, using CN Sep-pak cartridge, to improve detection limit quantification plasma samples, evaluated. involves addition methyl-paclitaxel as standard (i.s.). retention times I.S. were 2.8 4.0 min., respectively. assay linear over range 5 500 ng/mL, with ng/mL having coefficient variation (c.v.) < 10%. Standard calibration curves, performed three different days, had correlation coefficients always greater than 0.998. intra inter-day precision within 12%, accuracy included 102-110%. Paclitaxel recovery assessed at 15,250 determined be 85%. applicable clinical pharmacokinetic studies.
