Features and applications:
Sulfobutyl ether-beta-cyclodextrin sodium salt is a high water-soluble anionic cyclodextrin derivative. It can easily form non-covalent inclusion complexes with drug molecules, thus it has the good performances in enhancing drug stability, solubility and safety, reducing drug toxicity and hemolysis, covering up bad smell, and controlling drug release rate.
Sulfobutyl ether-beta-cyclodextrin sodium salt has been used in injection, oral, nasal and eye medication. Modification by charged functional units can improve the binding affinity of cyclodextrins for oppositely charged guests, so it has a special affinity for drugs with nitrogen elements.
Product performance:
1. Solubility:
Neutral, positive and negative APIs can be effectively combined with betadex sulfobutyl ether sodium to increase the solubility of the compound by 10 to 25,000 times.
2. Facilitate the drug
Betadex sulfobutyl ether sodium has a good biocompatibility and can be administered by injection, oral, ocular, nasal, topical and inhalation.
3. Good security
In general, it can be quickly and completely removed from the kidneys after administration. In vitro experiments and in vivo acute, subacute and chronic toxicity studies provide safe data and approval for use with pharmaceutical preparations.
4. Good stability
The interaction with sulfobutyricotriacodextrin provides a beneficial protective environment for the drug substance in its lipophilic chamber, while the hydrophilic surface provides excellent water solubility to provide solubility and stability.
