Patent ID: 7342048

Claim:
A bioabsorbable pharmaceutical formulation comprising a lactic acid-glycolic acid copolymer and a drug, wherein the lactic acid-glycolic acid copolymer has the following fraction contents for their respective molecular weights determined by gel-permeation chromatography: a fraction content of 0% to less than 5% for a molecular weight of 40,000 or more, a fraction content of 0.1% to less than 20% for a molecular weight of 16,000 or more and less than 40,000, a fraction content of 45% or more for a molecular weight of 5,000 or more and less than 16,000, a fraction content of 1% to less than 10% for a molecular weight of 2,000 or more and less than 4,000, and a fraction content of 5% or more for a molecular weight of 500 or more and less than 1,500.
