Ion Association Methods for the Determination of Fexofenadine in Pharmaceutical Preparations

Received10 May 2005

Two simple and sensitive Visible spectrophotometric methods (A and B) for the determination of Fexofenadine (FEX) in bulk sample and pharmaceutical formulations are described. Methods A and B are based on the formation of ion-association complex involving carboxylic acid group of FEX and the basic dyes, Safranin-O (SFN-O, method A), methylene blue (MB, method B). The results obtained in the above two methods are reproducible and are statistically validated and found to be suitable for the assay of Fexofenadine in bulk and its pharmaceutical formulations.
