UV Spectrophotometric Method for Estimation of Eprosartan Mesylate in Bulk and in Pharmaceutical Formulation

UV Spectrophotometric method provides a simple, efficient, precise and accurate method for development and validation of Eprosartan mesylate in bulk and its tablet formulation. The present study is based on measurement of the absorbance of Eprosartan mesylate solution in methanol: phosphate buffer pH 7.4 (10:90) at 293 nm in wavelength length of 200-400nm. Beers law was observed in the range of 5–25 ppm for this method. The developed method was validated in terms of accuracy, precision, linearity, limit of detection, limit of quantification which proves the suitability of this method for estimation of EPM in bulk and its tablet formulation. Results of recovery studies shows that the method was not affected by the presence of common excipients in tablets. Thus the method was found to be simple, economical, accurate and reproducible.
