CHARGE TRANSFER COMPLEX METHOD FOR THE ESTIMATION OF ETORICOXIB IN TABLETS
Abstract
A simple and sensitive spectrophotometric method employing acid-dye technique was developed for the estimation of etoricoxib in pharmaceutical dosage form. The proposed method is based on the formation of ion-pair complex of etoricoxib with an acid dye, which is extracted into chloroform and the absorbance measured at the λmax of the complex. The λmax of the ion-pair complex was found to be 414nm. Beer’s law was obeyed in the concentration range of 10-80 µg/ml .The proposed method is statistically validated and found to be useful for the routine determination of etoricoxib in tablets.
