Patent

CA 2288983

Covalent compositions of N,O-carboxymethyl chitosan (NOCC) are disclosed. NOCC can be intra- or intermolecularly linked, either through a direct bond or through a bridging moiety. Also disclosed are methods for preparing and using the covalent NOCC compositions. The NOCC compositions are useful in the administration of therapeutially active compounds and for wound management.

L'invention a trait à des compositions covalentes à base de N, O-carboxyméthyl-chitosane (NOCC) susceptible de liaison intramoléculaire ou intermoléculaire, que ce soit par le truchement d'une liaison directe ou d'une fraction de pontage. Elle concerne également des procédés de production de ces compositions à base de NOCC ainsi que leurs modes d'utilisation. Ces compositions à base de NOCC se révèlent utiles dans l'administration de composés, actifs du point de vue thérapeutique, ainsi qu'en matière de soins à exécuter sur des lésions.
