Product performance:
The introduction of hydroxypropyl breaks the intramolecular cyclic hydrogen bond of beta cyclodextrin, and overcomes beta cyclodextrin while maintaining the cyclodextrin cavity The main disadvantage of the poor water solubility of cyclodextrins.Pharmaceutical grade hydroxypropyl beta-cyclodextrin is an ideal injection solubilizer and pharmaceutical excipient. Its main functions in the field of medicine are as follows:
1. Solubilization and solubilization, solubilization of poorly soluble drugs, and improvement of the active ingredients of oily drugs Solubility, targeted drug delivery and protection of drug ingredient effectiveness.
2. Improve the bioavailability of the drug, so that the curative effect of the drug is increased or the dosage is decreased.
3. Adjust or control the release rate of the drug and reduce the toxic and side effects of the drug.
4. Cover up bad smell.
Scope of application:Pharmaceutical grade hydroxypropyl beta cyclodextrin can be used for oral drugs, injections, mucosal drug delivery systems (including nasal mucosa, rectum, cornea, etc.), It is a transdermal drug delivery system, a carrier for lipophilic targeted drugs, and can also be used as a protein protector and stabilizer.
