  • Enhanced stability of inverse thermal gelling composite hydrogels
    Patent number: 9205046
    Abstract: The present invention relates to a composite hydrogel comprising a blend of an aqueous solution of an anionic polysaccharide or a derivative thereof, such as hyaluronan (also commonly referred to as hyaluronic acid) or a derivative thereof and an aqueous solution of methylcellulose or another water soluble cellulose derivative thereof, having dispersed polymeric particles, such as polymeric hydrophobic particles therein selected from micro particles and nanoparticles, and wherein the stability of the hydrogel is enhanced relative to the stability of the hydrogel alone. The polymeric particles may contain at least one therapeutic agent, in which case each therapeutic agent exhibits a linear sustained release rate that can be tuned or altered by selecting the appropriate polymer formulation of the micro particles and/or nanoparticles.
    Type: Grant
