Using chitosan as drug carrier can stabilize drug components, promote drug absorption, delay or control the dissolution rate of drugs, help drugs reach target organs, resist acid and ulcer, and prevent the stimulation of drugs to the stomach.
Chitosan can be used to prepare microspheres, which have good adhesion and are more suitable for oral, nasal, gastrointestinal mucosa administration. The surface of chitosan microspheres is rich in polysaccharide chains, which can be recognized by specific cells or tissues, and can be targeted to deliver drugs to the lesion sites for storage and release. The surface of the chitosan microsphere can be connected with functional groups, and it can flexibly load different drugs by means of adsorption or encapsulation. The drug release of chitosan drug-loaded microspheres is related to the molecular weight of chitosan, and the release rate of general drugs decreases with the increase of molecular weight of chitosan, and the higher the concentration of chitosan, the lower the rate of drug diffusion from chitosan into biological media.
