Abstract:
An in situ gel-forming composition is disclosed. The in situ gel-forming composition comprises one or more absorbable polymers, solvents such as N-methyl-2-pyrrolidone, polyethylene glycol or DMSO, and optionally one or more bioactive agent. The composition forms a hydrogel or semi-solid mass on contact with an aqueous environment. The method of using in situ gel-forming composition for various applications is also disclosed.

Claim (Index 33):
An in situ gel-forming composition, comprising: one or more absorbable polymers; and\n a solvent selected from the group consisting of N-methyl-2-pyrrolidone (NMP), polyethylene glycol (PEG), dimethyl sulfoxide (DMSO) and mixtures thereof, wherein said composition is an injectable liquid at a temperature in the range of about 18\u00b0 C. to about 37\u00b0 C. and forms a hydrogel or semi-solid mass on contact with an aqueous environment; wherein the one or more absorbable polymers comprise a molecular chain having a X-Y-X or (X-Y)n structure, wherein X represents a relatively hydrophobic polyester block and Y represents a relatively hydrophilic block; and wherein the X-Y-X or (X-Y)n structure is formed by grafting hydrophobic X blocks from monomers selected from the group consisting of glycolide, lactide, \u03b5-caprolactone, p-dioxanone, trimethylene carbonate or combinations thereof, to hydrophilic Y blocks selected from the group consisting of polyoxyethylene, poly(oxyethylene-b-oxypropylene), polypeptide polyalkylene oxamate, polysaccharide, derivatives thereof, and liquid, high molecular weight polyether glycols interlinked with an oxalate or succinate functionalities in linear or branched form.
