Quality:

Pharm grade

 

Description:
Beta-cyclodextrin is made by extracting starch after the action of microbial enzymes. It is made of 7 glucose residues with β-1,4-glycosidic bond combined ring.

 

Characteristics & Applications:

Beta-cyclodextrin as a new pharmaceutical excipient is mainly used to enhance the stability of drugs, prevent oxidation and decomposition of drugs, improve the dissolution and bioavailability of drugs, reduce the toxic and side effects of drugs, and mask the peculiar smell of drugs.
