Simultaneous Estimation of Satranidazole and Ofloxacin in Tablet Dosage Form by High Performance Liquid Chromatography
A Simple, fast and precise reversed phase high performance liquid chromatographic method is developed for the simultaneous determination of satranidazole and ofloxacin. Chromatographic separation of these drugs were performed on Kromasil C18 column (250 x 4.6 mm, 5 µ) as stationary phase with a mobile phase comprising of 20 mM potassium dihydrogen phosphate: acetonitrile in the ratio of 60:40 (v/v) containing 0.1% glacial acetic acid at a flow rate of 1 mL/min and UV detection at 318 nm. The linearity of satranidazole and ofloxacin were in the range of 1.5 to 3.6 µg/mL and 1.0 to 2.4 µg/mL respectively. The recovery was calculated by standard addition method. The average recovery was found to be 100.63% and 100.02% for satranidazole and ofloxacin respectively. The proposed method was found to be accurate, precise and rapid for simultaneous determination of satranidazole and ofloxacin
