Abstract:
Background: Desidustat (DES) belongs to a new category of drugs, i.e., Hypoxia-Inducible
Factor (HIF) propyl hydroxylase inhibitor, and is used for the treatment of anemia in chronic kidney
disease. However, no method has yet been reported in the literature for the estimation of drugs.
Objective: The objective of the study is to develop a simple, precise, and accurate method for determining
DES in bulk and pharmaceutical dose form.
Methods: The physicochemical characterization of the drug was performed using methanol as a solvent
to establish the identity. According to ICH Q2 criteria, validation characteristics, such as specificity,
linearity, accuracy, precision, limits of detection and quantification, and robustness, were assessed.
Results: Maximum absorbance wavelength was observed at 229 nm. The sample solution remained
stable for up to 12 hours. The linear response from 2 to 12 μg/ml of DES was y = 0.1087x + 0.0962
and r2 = 0.9963. The accuracy was between 100 to 101%. Precision was recorded under three criteria:
repeatability, intraday and interday, for which results fell within the acceptable ranges (<2%). The limit
of detection (LOD) and limit of quantification (LOQ) of the technique were 0.434 μg/ml and 1.316
μg/ml, respectively.
Conclusion: The proposed method was found to be beneficial for drug monitoring and the ongoing
analysis of DES in research and quality control laboratories. This approach is simple, precise, rapid,
economical, and sensitive.
