A new simple, sensitive, accurate and precise method has been developed for the simultaneous estimation of Levofloxacin hemihydrate and Cefpodoxime proxetil in pharmaceutical dosage form by RP-HPLC. After optimization good chromatographic separation was achieved by isocratic mode with a mixture of K2HPO4 and methanol pH 8 in the ratio of 40:60 v/v as the mobile phase with YMC C18 (250 mm x 4.6 mm i.d x 5 μm) column as stationary phase at flow rate of 1mL/min and detection wavelength of 275 nm. The retention time of Levofloxacin hemihydrate and Cefpodoxime proxetil were found to be 2.8 and 3.9 min respectively. The linearity of this method was found in the concentration range of 250 μg/mL to 750 μg/mL for Levofloxacin hemihydrate and 200 μg/mL to 600 μg/mL for Cefpodoxime proxetil. The method was extensively validated according to ICH guidelines Q2B for Linearity, Range, Accuracy, Precision, Specificity and Robustness
