ABSTRACT

A sensitive and accurate reversed– phase high performance liquid chromatography (RP-HPLC) method with UV absorbance detection at 289 nm was developed and validated for the determination and quantification of besifloxacin (BSF) in rat plasma. Ofloxacin was used as an internal standard (IS). The sample was prepared by liquid extraction of BSF from plasma, using methanol and acetonitrile (70:30). The chromatographic separation was achieved with octadecylsilane (ODS-3), Hypersil® C18 column (250 mm×6mm×5μm). The chromatographic runtime was less than 5 minutes where the retention time of internal standard and the drug was 2.15 min and 3.30 min respectively. A standard curve with a regression coefficient (r2) 0.999 was obtained in the range of 0.025-20 μg/mL. The method was validated with respect to linearity, range, precision, accuracy and robustness according to ICH guidelines. The method was found to be accurate and robust with a runtime of less than 5 minutes. Hence, the present method was rapid and economical to use for clinical studies as well as to analyze the drug in different plasma samples.
