Application（Only For Reference ）
Application of chitosan in pharmaceutical
indus tr y :Ac cording to the Chinese
Pharmacopoeia (Part IV), chitosan is used
inpharmaceutical excipients, disintegrants,
thickeners, etc.
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.
