Chitosan and chitosan derivatives have different properties due to molecular parameters, such as degree of deacetylation and molecular weight. In this article, we present a paper that examined the effect of these parameters on the hemostatic effect of chitosan. Another topic is the long-term stability of chitosan hydrogels according to ICH guidelines.

Chitosan is not only used for feverish laboratory-scale research, but also for specific application in chitosan-based products for a wide variety of indications, which are being tested in clinical studies. In this article we provide an insight into current clinical studies on chitosan and present the results of two studies on chronic wound healing and improved hemostasis after puncture of the radial artery.
