Chirality seems to be a pivotal technique in the field of science. Research teams are quite well versed in empirical separation, however, at the same time, they are clueless about the evolution of chiral separation. As per the guidelines of the United States Food and Drug Administration (US FDA), chiral drugs must be unraveled before they are sold to the public. Stereogenic separation has gained prominence during the last 10 decades due to the disparate biological function of enantiomers in the stereogenic environment. Chiral drugs exhibit a wide range of bioavailability, distribution, and pharmacodynamic properties; concomitantly, they exert divergent pharmacological and toxicological properties. Enantiomeric chiral products could be considered safe and potent in combating various diseases, including metabolic diseases like diabetes. Several studies have delineated the development of a novel analytical and bioanalytical method to detect/segregate/quantify chiral chemical components in medicinal chemistry. The same physicochemical characteristics of enantiomers have been proven to be beneficial to the estrangement of stereogenic compounds. Furthermore, the advancement of bioanalytical methods is also critical to shedding light on the destiny of distinct enantiomers in the biological environment. HPLC (High-Performance Liquid Chromatography) and CE (Capillary Electrophoresis) have been the most commonly employed separation techniques. But the technical advances are required to enhance the efficiency of detection and quantification of chiral molecules on a large scale. With technical advances, the current review delineates the need for the chiral separation of stereogenic antidiabetic drug compounds. Furthermore, this research is focused on the enantioseparation of chiral antidiabetic drugs and a brief overview of the analytical and bioanalytical methods conducted on distant chiral antidiabetic drugs to improve the efficiency of chiral separation.
