Abstract
Compositions comprising a glycosaminoglycan (e.g., a hyaluronan, hyaluronic acid, hyaluronate, sodium hyaluronate, dermatan sulfate, karatan sulfate, chondroitin 6-sulfate, heparin, etc.) in combination with at least one component selected from; i) polyglycols (e.g., polyethylene glycol), ii) long chain hydroxy polyanionic polysaccharides (e.g., dextran, sodium alginate, alginic acid, propylene glycol alginate, carboxymethyl cellulose and carboxyethyl cellulose, hydroxyl ethyl starch, hydroxyl propyl methyl cellulose, hydroxy propyl ethyl cellulose, hydroxy propyl cellulose, methyl cellulose, polylysine, polyhistidine, polyhydroxy proline, poly ornithine, polyvinyl pyrolidone, polyvinyl alcohol, chitosan, etc.) and iii) long chain Nitrogen containing polymers (e.g., Polylysine, Polyvinylpyrrolidone, and polyvinyl alcohol). The invention also includes methods for using such compositions (e.g., as substance delivery materials, tissue fillers or bulking agents, as moistening or hydrating agents, etc.).
