Abstract

A simple, accurate, precise and specific spectrophotometric method has been developed for simultaneous determination of racecadotril and ofloxacin in its combined tablet dosage form by using methanol as a solvent. The method involves absorbance correction based on measurement of absorbance at two wavelengths at 231 nm and 323.40 nm. Method follows Beer’s linearity in the range of 10-24 μg/ml for racecadotril and 20-48 μg/ml Ofloxacin both. The mean % recoveries were found to be in the range of 99.22 – 100.66 % and 99.62 – 100.19 % for racecadotril and ofloxacin respectively. LOD and LOQ were found to be 0.1922μg/ml and 0.5826 μg/ml for racecadotril and 0.1063 μg/ml and 0.3223 μg/ml for ofloxacin respectively. Assay results of market formulation were found to be 99.24 % and 99.25 % for racecadotril and ofloxacin respectively. The proposed method has been validated as per ICH guidelines and successfully applied to the estimation of racecadotril and ofloxacin in their combined Tablet dosage form.
