Quantitative determination of sparfloxacin in rat plasma by liquid chromatography/tandem mass spectrometry

초록

Sparfloxacin, a fluoroquinolone antibiotic, is used for the treatment of bacterial infection A quantification method using mass spectrometry was developed for the determination of sparfloxacin in rat plasma After simple protein precipitation with acetonitrile, the analytes were chromatographed on a reversed-phase C-18 column and detected by liquid chromatography/tandem mass spectrometry with electrospray ionization The accuracy and precision of the assay were in accordance with FDA regulations for validation of bioanalytical methods This method was applied to measure the plasma sparfloxacin concentrations after a single oral administration of sparfloxacin in rats Copyright (C) 2010 John Wiley & Sons, Ltd
