Medicaments containing gelatin cross-linked with oxidized polysaccharides

Abstract

The present invention relates to a wound dressing comprising a biopolymer matrix comprising gelatin cross-linked with an oxidized polysaccharide. Preferably said oxidized polysaccharide comprises an oxidized dextran or an oxidized xanthan. Preferably said matrix is in the form of a hydrated film, a hydrated or dry foam, dry fibers which may be fabricated into a woven or non-woven tissue, hydrated or dry microbeads, dry powder; or said matrix is covered with a semipermeable film, so as to control the humidity of the wound covered with the dressing, with the permeability chosen so as to maintain this humidity within a therapeutically optimal window. A polysulfated polysaccharide with a M.W. greater than 30,000 kDa is mechanically entrapped during the formation of said matrix.
