Abstract
<em>This study presents new spectrophotometric method for the determination of Irbesartan. So far, no Area under Curve Spectrophotometric method has been reported for the estimation of Irbesartan from pharmaceutical dosage form. This paper deals with validation and development of a method by Area Under Curve for the assay of Irbesartan from pharmaceutical dosage forms. The principle for AUC curve method is “the area under two points on the mixture spectra is directly proportional to the concentration of the component of interest”. The area selected between 203 to 211 nm for determination of Irbesartan. The drug follows Beer-Lambert’s law over the concentration range of 5-25 μg/ml for Irbesartan. In accuracy study the % recovery of Irbesartan in bulk drug samples was ranged 96.45-93.84%, which indicates that the method was accurate. Validation of the proposed method was carried out for its accuracy, precision, and specificity according to ICH guidelines. The proposed methods can be successfully applied in routine work for the determination of Tigecycline in its pharmaceutical dosage form.</em>
