Application
Beta cyclodextrin is widely used in the separation of organic compounds and for organic synthesis, as well as medical excipients and food additives. The inclusion of natural cyclodextrin and modified cyclodextrin and some drug molecules that are not biocompatible are now prepared. It not only increases the biocompatibility of the drug, but also plays the role of sustained release.
