A review on analytical methods of antigout agents

The aim of this study was to provide information of the development in analytical perspective of impurity profiling, force degradation, and bioanalysis of pharmaceutical drug substance and drug products used for the treatment of gout. This information was discussed on the basis of year of publication, matrix (active pharmaceutical ingredient, dosage form, and biological fluid), sample preparation technique, column and types of elution in chromatography (isocratic or gradient), detector, and therapeutic categories of drug, which were used for analysis. It focuses mainly on analytical methods including hyphenated techniques for the identification and quantification of impurity, degradants, and metabolites in different pharmaceutical and biological matrices.
