1. Carrier materials
Chitosan, which acts as a drug carrier, is touted for stabilizing the composition of a drug, promoting its absorption, slowing or controlling its dissolution, helping the drug reach its target organ, and being acidresistant, ulcer-resistant as well as preventing gastric irritation.
2. Film forming materials
Chitosan can be used as a film-forming material for film preparation, such as oral film preparation and traditional Chinese medicine film preparation. Its relative molecular weight has a prominent influence on the filmforming property and film properties. Generally, the lower the molecular weight, the lower the tensile strength and the stronger the permeability of the film. Appropriate crosslinking agents can be selected to improve the strength and change the barrier properties of the film.
