INTERACTIVE DRESSINGS FOR TREATMENT OF DERMATOLOGICAL DISEASES

摘要

Object of the invention is an interactive dressing the treatment of dermatological disorders. The invention comprises: a support, preferably a tissue non-tissue gauze, a hydrogel of a bioadhesive polymer like chitosan or hydroxyethylcellulose and liposomal systems containing an active principle of protein nature. It is a solid therapeutic system consisting of a dispersion of liposomes in hydrogel adsorbed on a tissue non-tissue gauze. The association of hydrogel with liposomal systems allows the site specific and prolonged release of active substances, through intracellular transfer of liposomes and therefore of the encapsulated drug. In addition to act as a storage form, liposomes protect the drug from enzymatic attacks, thus preserving its activity. The therapeutic system containing preferably the prolidase enzyme is used for the treatment, in human and mammals, of dermatological disorders with or without epithelial ulcers, preferably for treatment of ulcers in subjects affected by genetic prolidase deficiency.
