ABSTRACT

This research aims to establish an UV-Visible spectroscopic technique for Bilastine by applying a multivariate regression equation that is precise, sensible, and reproducible method. Proposed technique depends on the equation of the linear regression performed by taking absorbance at five distinct wavelengths. Bilastine maximum absorbance was obtained at 274 nm using distilled water as the solvent. Graph obtained from concentration 16-24 ?g mL-1 resulted in linear curve and the regression coefficient was obtained as 0.9995 %. RSD values for Intra-day, as well as Inter-day precision, was obtained as 0.4817 and 0.3691. The assay value determined was between 99.70 % - 101.46 % w/w. Keywords: Bilastine, Antihistamine, UV spectrophotometry, Multivariate calibration, Assay, ICH guidelines
