Summary for Patent: 7,767,656
Title:Blends of temperature sensitive and anionic polymers for drug delivery
Abstract: A physical blend of inverse thermal gelling and shear-thinning, thixotropic polymers that has a lower gelation temperature than the thermal gelling polymer alone is provided. The blend results in an injectable hydrogel that does not flow freely at room temperature, but is injectable due to its shear-thinning properties. The thermal-gelling properties of the polymer promote a more mechanically stable gel at body temperature than at room temperature. The polymer matrix gel has inherent therapeutic benefit and can also be used as a drug delivery vehicle for localized release of therapeutic agents.
