    摘要： Polymeric compositions having improved capability of solubilizing a drug in a hydrophilic environment to form a solution, comprising: a biodegradable polyester oligomer; and biodegradable AB-type, ABA-type, or BAB-type block copolymers are disclosed. The copolymers are comprised of about 50.1 to 65% by weight of a biodegradable, hydrophobic A polymer block comprising a biodegradable polyester, and about 35 to 49.9% by weight of a hydrophilic B polymer block comprising a polyethylene glycol (PEG), and wherein the block copolymer has a weight averaged molecular weight of between 2400 to 4999. The biodegradable polyester oligomer of said composition is within a range of 0.01% to 30% by weight of the total polymer mixture, and the content of the biodegradable AB-type, ABA-type, or BAB-type block copolymer is within a range of 70% to 99.99% by weight of the total polymer mixture.

    摘要： A composition and method for releasing a bio-active agent or a drug within a biological environment in a controlled manner is disclosed. The composition is a dual phase polymeric agent-delivery composition comprising a continuous biocompatible gel phase, a discontinuous particulate phase comprising defined microparticles and an agent to be delivered. A microparticle containing a bio-active agent is releasably entrained within a biocompatible polymeric gel matrix. The bio-active agent release may be contained in the microparticle phase alone or in both the microparticles and the gel matrix. The release of the agent is prolonged over a period of time, and the delivery may be modulated and/or controlled. In addition, a second agent may be loaded in some of the microparticles and/or the gel matrix.
