Abstract:
The present invention is directed to polymeric matrices for the controlled release of a hydrophilic bioactive agent. Generally, the elution control matrix includes a polymeric matrix having a first polymer and a plurality of microparticles that include the hydrophilic bioactive agent. In one embodiment, the matrix includes a polymer comprising hydrophilic and hydrophobic portions. In another embodiment, the microparticles include a crosslinked hydrophilic polymer.
