Patent ID: 8187640

Claim:
A liquid polymer composition formulated for administering into a body of an animal or human, comprising: (a) a biodegradable liquid polymer comprising a copolymer of lactide and caprolactone with a molar ratio from 75/25 to 25/75 and a molecular weight of 2000 daltons to 20,000 daltons, the molecular weight as determined by gel permeation chromatography using a multi-angle light-scattering detector (GPC-MALS); (b) a biocompatible organic solvent; and (c) a therapeutically effective amount of a biologically active agent; wherein the composition, when placed in contact with body fluid of an animal or human, remains in a liquid form and does not form a solid in situ after dissipation of the organic solvent from the composition into said body fluid.
