More Information
Summary:The present invention relates to a delivery system for pharmaceutical compositions relying in part on an ionic interaction to control and facilitate release of the treating agent. More specifically, the invention relates to an extended controlled-release system having an ionic treating agent and an ionic polymer, wherein the polymer is sufficiently ionized to release the treating agent in a controlled manner over an extended period of time and the composition does not require an emulsion system for administering the treating agent.
