Development and Validation of RP-HPLC for Simultaneous Estimation of Cefpodoxime Proxetil and Dicloxacillin Sodium Tablets

The present work deals with the development of a precise, accurate, simple, specific, reliable and less time consuming RP-HPLC method for the estimation of Cefpodoxime Proxetil and Dicloxacillin Sodium tablets .The chromatographic separation was achieved on a Inertsil C18 ODS(4.6 x 250mm, 5􀀀m) with a mobile phase combination of methanol and water (50:50) v/v at a flow rate of 1.0 ml/min, and the detection was carried out by using PDA detector at 290 nm. Ambient column temperature has maintained. The total run time was 10mins. The retention time of Dicloxacillin Sodium and Cefpodoxime Proxetil were found to be 2.9 min. and 3.5 min. respectively. The performance of the method was validated according to the present ICH guidelines.
