- Abstract
- In this study, a sensitive, simple and reliable method for the quantification of docetaxel in rat plasma was developed and validated using liquid chromatographytandem mass spectrometry (LC-MS/MS). The plasma samples were prepared by protein precipitation, and paclitaxel was used as an internal standard (IS). Chromatographic separation was achieved using a Gemini C18 column (2.0x150mm, 5 mu m) with a mobile phase consisting of 0.1% formic acidacetonitrile (30:70, v/v). The precursorproduct ion pairs used for multiple reaction monitoring were m/z 808.5527.5 (docetaxel) and m/z 854.2286.5 (IS, paclitaxel). A calibration curve for docetaxel was constructed over the range 11000ng/mL. The developed method was specific, precise and accurate, and no matrix effect was observed. The validated method was applied in a comparative pharmacokinetic study in which two docetaxel formulations, SID530, a new parenteral formulation of docetaxel with hydroxypropyl--cyclodextrin (HP--CD), and Taxotere, were administered to rats at a dose of 5mg/kg. For SID530 and Taxotere, the mean C0 values were 1494 and 1818ng/mL, respectively, and the AUClast values were 837 and 755hng/mL, respectively. These two formulations did not show any statistical differences with regard to the pharmacokinetic parameters, thus establishing that the SID530 and Taxotere products are pharmacokinetically comparable in male rats.
