AIM: To present the research results concerning enhanced antimicrobial and release properties of the chitosan derivative with sulfadiazine/hyaluronic acid polyelectrolyte complex (PEC) hydrogel. MATERIAL AND METHODS: The PECs have been prepared from chitosan of different molecular weight, sulfadiazine chitosan derivative and sodium hyaluronate. The complex structure was assessed by FT-IR spectroscopic method and swelling capacity was followed by weighing measurements. RESULTS: It has been establish that chitosan derivative influenced both PEC properties and swelling capacity. CONCLUSIONS: Incorporation in PEC of the sulfadiazine chitosan is a new way to combine bacteriostatic effect of chitosan with that of sulfadiazine, to control properties, antimicrobial activity in the treatment of the wound.
