ABSTRACT:
A drug delivery system is provided which is in the form of hydrogel beads employed in a new interpenetrating polymer network which is formed by swelling hydrogel beads with an acrylic swelling agent and reacting the swelling agent with a cross-linking agent. The drug delivery system has superior drug loading capacity and controlled release characteristics.
