ABSTRACT

 

The present manuscript describe simple, sensitive, rapid, accurate, precise and economical spectrophotometric method for the simultaneous determination of Ofloxacin and Cefpodoxime proxetil in combined tablet dosage form. The method is based on the simultaneous equations for analysis of both the drugs using methanol as solvent. Ofloxacin has absorbance maxima at 297 nm and cefpodoxime proxetil has absorbance maxima at 236.2 nm in methanol. The linearity was obtained in the concentration range of 2-12 μg/ml and 4-24 μg/ml for Ofloxacin and Cefpodoxime proxetil, respectively. The concentrations of the drugs were determined by using simultaneous equations at both the wavelengths. The mean recovery was 99.63 ± 0.47 and 99.57 ± 0.36 for Ofloxacin and Cefpodoxime proxetil, respectively. 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 Ofloxacin and Cefpodoxime proxetil was proved by validation. The proposed method was found to be simple and sensitive for the routine quality control application of Ofloxacin and Cefpodoxime proxetil in pharmaceutical tablet dosage form. The results of analysis have been validated statistically and by recovery studies.

 

Key words: Cefpodoxime proxetil, Ofloxacin, recovery, simultaneous equations method, tablet, validation.
