The potential of beta-cyclodextrins as a pharmaceutical aid has been established through several decades of research. However, some beta-cyclodextrins are reported to be toxic causing deleterious effects on long term usage. In the recent past, Sulfobutyl Ether Beta Cyclodextrin Sodium, a modified beta-cyclodextrin has captured interest as a comparatively safer and effective beta-cyclodextrin for increasing the solubility and the bioavailability of biopharmaceutical classification system class II drugs. Sulfobutyl Ether Beta Cyclodextrin Sodium has demonstrated immense potential in addressing solubility and stability issues associated with formulation of drugs. 

Our factory was established in 1999 and has focused on the production of cyclodextrin for more than 20 years. The Sulfobutyl Ether Beta Cyclodextrin Sodium produced by our factory has high yield, low price and guaranteed quality, we welcome you to inquire about the product details.
