ABSTRACT:
An accurate, specific and precise new Absorption Ratio method was developed for the simultaneous determination of Lansoprazole and Naproxen. The method involved Q-absorption analysis based on the measurement of absorbance at two wavelengths, i. e ?max of Lansoprazole (284nm) and for Naproxen was (271nm) and Iso-absorptive point of both drugs (275nm). The linearity was found to be 10-35µg/ml (r2 =0·999) for NAP and 5-30µg/ml (r 2 =0·998) for LAN. Validation was performed as ICH guidelines for Linearity, accuracy, precision, LOD and LOQ. The limit of quantification of NAP was found to be 0·15µg/ml and for LAN was 1·7µg/ml. The limit of detection of NAP was found to be 0·04µg/ml and for LAN was 0·5µg/ml. The indicating proposed spectrophotometric method was accurate and precise for estimation of NAP and LAN in tablet dosage form.
