Development and validation of analytical methods for the simultaneous estimation of Nimorazole and Ofloxacin in tablet dosage form

Two simple, rapid, accurate and precise spectrophotometric methods have been developed for simultaneous estimation of Nimorazole and Ofloxacin from tablet dosage form. Method І involves formation of ‘simultaneous equations’ at 304 nm (λ max of Nimorazole) and 287.5 nm (λ max of Ofloxacin); while Method ІІ involves, formation of ‘Absorbance ratio equation’ at 301(isoabsorptive point) and 287.5 nm (λ max of Ofloxacin) using distilled water as a solvent. The linearity was observed in the concentration range of 5 - 25 μg/ml for Nimorazole and 2 - 10 μg/ml for Ofloxacin. The results of analysis have been validated statistically and by recovery studies and were found satisfactory.
