UV SPECTROPHOTOMETRIC QUANTIFICATION OF AZILSARTAN PHARMACEUTICALS EMPLOYING MULTIVARIATE CALIBRATION TECHNIQUE Authors: Abdullah Khan AK , SEETHARAMAN R*, MANIKANDAN K
ABSTRACT
In order to accurately determine the concentration of Azilsartan medoxomil in formulations
and bulk, the current study advises developing a novel approach and evaluating it. This
analytical process can be summarized as sensitive, precise, and rapid. With the aid of a UV
spectrophotometer and a multivariate calibration technique, the analytical approach was carried
out. The relationship between concentration and absorbance, established at five different
wavelengths, including the highest peak absorbance at 250 nm, was used to establish this
multivariate calibration technique with methanol as blank. Using the linear regression
equations and other mathematical and statistical techniques, the strategy was verified using the
ICH Q2 (R1) criterion. Accuracy, linearity, and other validation criteria listed in the
instructions have all been attained. When used for periodic evaluations of drugs and
formulations, this technology is sensitive, cost-effective, and yields reliable results.
