ACTIVE AGENT DELIVERY SYSTEMS, INCLUDING A SINGLE LAYER OF A MISCIBLE POLYMER BLEND, MEDICAL DEVICES, AND METHODS

摘要

An active agent delivery system that includes two or more active agents in a layer of a miscible polymer blend having at least two miscible polymers; wherein delivery of at least one of the active agents occurs predominantly under permeation control; and further wherein the permeability of the active agent that is to be released faster is greater than the permeability of the other one or more active agents.
