Abstract
Simple, accurate, rapid and sensitive method has been developed for the estimation of Valsartan in bulk and pharmaceutical formulations. The method is based on the formation of ion association complex of the drug with eriochrome black-T in acidic buffer of pH 3.5 followed by extraction into chloroform. The linearity range of Valsartan with eriochrome black-T was found to be 50 – 250 µg/mL. The developed method was found to be precise and accurate from the statistical validation of the analytical data. The proposed method has been successfully applied for analysis of dosage formulations.
