DEVELOPMENT AND VALIDATION OF SPECTROPHOTOMETRIC METHOD FOR SIMULTANEOUS DETERMINATION OF CEFPODOXIME PROXETIL AND OFLOXACIN IN TABLETS

The present manuscript describes simple, sensitive, rapid, accurate, precise and economical spectrophotometric method for the simultaneous determination of cefpodoxime proxetil and ofloxacin in combined tablet dosage form. The method is based on the simultaneous equations for analysis of both the drugs using methanol as solvent. Cefpodoxime proxetil has absorabance maxima at 236 nm and ofloxacin has absorbance maxima at 299 nm in methanol. The linearity was obtained in the concentration range of 5-29 μg/ ml and 1-13 μg/ml for cefpodoxime proxetil and ofloxacin respectively. The concentrations of the drugs were determined by using simultaneous equations at both the wavelengths. The method was successfully applied to pharmaceutical dosage form because no interference from the tablet excipients was found. The suitability of this method for the quantitative determination of cefpodoxime proxetil and ofloxacin was proved by validation. The proposed method was found to be simple and sensitive for the routine quality control application of cefpodoxime proxetil and ofloxacin in pharmaceutical dosage form. The result of analysis has been validated statistically and by recovery studies.
