RP-HPLC METHOD DEVELOPMENT AND VALIDATION OF CEFPODOXIME PROXETILAbstract
A new simple and rapid reverse-phase high-performance liquid chromatographic (RP-HPLC) method has been developed and validated for simultaneous estimation of cefpodoxime proxetil in bulk drugs and pharmaceutical dosage form. The separation was accomplished on a sunfire C-18 (250 × 4.6 mm, 5 μm) column with a mobile phase consisting of Methanol; Water (70:30 v/v) at a flow rate of 0.8 mL/min. The eluents were monitored at 236 nm by using PDA detector. The retention time for cefpodoxime proxetil was found to be 4.5 min, respectively. The cefpodoxime proxetil followed linearity in the concentration range of 5-30 μg/mL (r2 = 0.998). The amount of drug estimated by proposed method was found to be in good agreement with label claim. The developed method was validated for sensitivity, accuracy, precision. The LOD and LOQ values were found to be 0.0004 and 0.0012 μg respectively for cefpodoxime proxetil. The proposed method can be used for routine analysis of both these drugs simultaneously in their combined dosage form.
