Abstract
Polymeric matrices including microparticles that provide sustained release of a hydrophilic bioactive agent are described. The matrices can be in the form of a coating on the surface of an implantable medical article or an in situ formed matrix. The microparticles of the matrix include a first polymer and a second polymer that modulates release of the hydrophilic bioactive agent from the matrix.
