The purpose of this research study is to develop a novel, simple, precise, accurate and economical method for determination of Apixaban API isomers. This chromatographic method was developed on chiralpak IA column(250 x 4.6 x 5µm) with isocritic technique. The detection of impurities was observed at wavelength 290nm. This analytical method was validated and regression analysis showed R value (correlation coefficient) > 0.999 for Apixaban and its isomeric impurities. A solution of Apixaban in dichloromethane was found stable up to 48 hrs. The degradation study was done within the given guidelines prescribed by ICH. The method is validated for linearity, accuracy and precision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
