Development and validation of analytical methods for the simultaneous estimation of Nimorazole and Ofloxacin in tablet dosage form
Keywords:
Ofloxacin, Nimorazole, Simultaneous equation method, Absorbance ratio methodAbstract
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.
