- 摘要: etadex Sulfobutyl Ether Sodium is a sodium salt produced when betacyclodextrin is alkylated by 1,4-butanesulfonic acid lactone under alkaline conditions. It is an anion, highly water-soluble betacyclodextrin derivative. Betadex Sulfobutyl Ether Sodium is can be well combined with the drug molecules to form non-covalent complex, thereby enhancing the stability, water solubility, and safety of the drug, reducing its renal toxicity, easing drug hemolysis, controlling drug release rate, covering bad smell, etc.
