Rapid and sensitive liquid chromatography coupled with electrospray ionization tandem mass spectrometry method for the analysis of paclitaxel, docetaxel, vinblastine, and vinorelbine in human plasma.
Therapeutic Drug Monitoring 2014 June
BACKGROUND: A rapid and sensitive analytical method using liquid chromatography coupled with electrospray ionization tandem mass spectrometry (LC-MS/MS) was developed for the determination of paclitaxel, docetaxel, vinblastine, and vinorelbine in human plasma.
METHODS: A simple liquid-liquid extraction procedure was applied using only 100-μL plasma. Chromatographic separation of these anticancer drugs was achieved with an isocratic mobile phase consisting of acetonitrile/aqueous buffer (10 mmol/L ammonium acetate and 0.1% formic acid in 70:30, vol/vol) at a flow rate of 0.25 mL/min in a short time (4.5 minutes).
RESULTS: The calibration curves for paclitaxel, docetaxel, vinblastine, and vinorelbine in spiked human plasma ranged from 25 to 2500, 10 to 1000, 10 to 1000, and 10 to 1000 ng/mL, respectively. The squares of the linear correlation coefficients were all more than 0.99. The intraday and interday relative standard deviations across 3 validation runs over the entire concentration range were less than 9.2%.
CONCLUSIONS: The established method should be helpful for the pharmacokinetic monitoring of paclitaxel, docetaxel, vinblastine, and vinorelbine in the human plasma of non-small cell lung cancer patients.
