ABSTRACT:
Delivery systems manufactured in the form of polymeric compositions for the controlled delivery of macromolecules to environments of use are disclosed. The systems are characterized as two-phase compositions comprising a phase formed of an insoluble polymeric matrix having limited water sorptivity containing in admixture therein an interpenetrating phase formed of a particulate hydrophilic water swellable, biologically active macromolecular material.
