Product Performance:
The introduction of hydroxypropyl breaks the intramolecular cyclic hydrogen bonding of betacyclodextrin, which overcomes the main disadvantage of poor water solubility of betacyclodextrin while maintaining the cyclodextrin cavity. Pharmaceutical hydroxypropyl betacyclodextrin is an ideal solubilizer and drug excipient for injection, and its main functions in the pharmaceutical field are as follows:
1. increase the solubility of drugs, and improve the hydrophilicity of insoluble and oil-soluble drugs; 2. adjust or control the hydrophilicity of drugs.
2. adjusting or controlling the release rate of drugs, protecting the effectiveness of drug components, the application of targeted drug delivery field has great prospects; 3. improving the bioavailability of drugs, protecting the efficacy of drug components.
3. Improve the bioavailability of drugs, so that the efficacy of the agent to increase or reduce the dosage of drugs; 4.
4. can reduce the toxic side effects of drugs, mask the bad odor; 5. can improve the physical and chemical properties of drugs
5. It can improve the physical and chemical properties of the drug, enhance the stability of the drug and improve the prescription.
Scope of application:
Pharmaceutical hydroxypropyl betacyclodextrin can be used for oral drugs, injections, mucosal drug delivery system (including nasal mucosa, rectum, cornea, etc.), transdermal absorption drug delivery system, lipophilic targeted drug carriers, but also can be used as a protective agent and stabilizer of protein.
