Rapid and sensitive LC-MS method for pharmacokinetic study of vinorelbine in rats.
A rapid and sensitive LC-electrospray ionization-MS method was developed for determining vinorelbine in rat plasma. A 100 microL plasma sample was treated using a protein precipitation procedure and was chromatographed within 4 min using an Inertsil ODS-3 C(18 )(2.1 x 50 mm, 5 microm) column. The selected ion monitoring ions [M + H](+) were m/z 779 and m/z 811 for vinorelbine and vinblastine (internal standard), respectively. The method validation showed that the calibration curve for vinorelbine was linear over a concentration range of 1-1000 ng/mL with lower limit of quantification at 1 ng/mL. The method has been successfully applied to pharmacokinetics in rat plasma.
