Betadex Sulfobutyl Ether Sodium is a sodium salt produced when Betadex is
alkylated by1,4-butanesulfonic acid lactone under alkaline conditions. It is an
anion, highly water-soluble Betadex derivative. Betadex Sulfobutyl Ether Sodium
can bewell combined with the drugmolecules to form non-covalent
therebyenhancingthe stability, water solubility, and safety of the
drug, reducingits renal toxicity, easing drughemolysis, controllingdrugrelease
rate, covering bad smell, etc.
