<P>New ion pair colorimetric method has been developed for the estimation of dronedrone in bulk and in tablet formulation using methyl orange dye as an ion paring complexant using pH 4 buffer. The developed method h validated for its sensitivity and specificity. The intensity of ion pair complex Of dronedrone and methyl orange found linear over the range of 2-20 mu g mL(-1) with a correlation coefficient of 0.9958. The inter and intraday precision, ace-tiny, stability LOD, LOQ placebo interference, robustness and ruggedness Were evaluated during validation The % RSD found for the recovery of the method resulted with low value of about 0.72-0.99 and with good precision. From the results obtained the developed method was found suit:able and comparable in terms of estimating dronedrone in formulation With that of existing methods.</P>
