The application of chitosan in pharmacy is as follows:
1. Drug delivery carrier:
Nano-carrier: Chitosan can be used to prepare nano-carriers such as nanoparticles and nano-micelles for drug delivery. These carriers are beneficial to improve the solubility, stability and bioavailability of drugs, and can regulate the release rate of drugs.
microspheres and microcapsules: chitosan can also be used to prepare microspheres and microcapsules, and drug can be wrapped in them to realize targeted and slow-release drug delivery.
second, biodegradable materials:
biodegradable drug wrapping material: chitosan is a biodegradable polysaccharide, so it can be used as drug wrapping material, which can not only effectively protect drugs, but also gradually degrade and release drugs in the body.
wound dressing and bio-gelling agent: chitosan has good biocompatibility and biodegradability, and can be used to prepare wound dressing and bio-gelling agent, which plays a role in wound healing.
III. Drug release control:
Controlled release system: Chitosan can be used to prepare a controlled release system. By adjusting the characteristics and structure of chitosan, drug release can be controlled, such as slow release and controlled release.
Sustained-release tablets: Using the solubility and degradability of chitosan, sustained-release tablets can be prepared to provide more lasting and stable drug release.
IV. Biocompatibility and bioactivity:
Biocompatibility: Chitosan has good biocompatibility and high compatibility with human tissues, and can be used to prepare biomedical materials and medical devices.
Enhancement of biological activity: After being combined with other substances, chitosan can also enhance its biological activity, such as synthesizing composite materials or carriers to enhance the bioavailability and activity of drugs.
in pharmacy, chitosan has a wide range of applications, and its controlled release, biodegradability and biocompatibility make it an ideal choice for preparing drug delivery systems and biomedical materials. In the research and development of new drugs and the design of drug delivery system, the application of chitosan is expected to bring more innovation and progress to the field of pharmacy.
