Abstract
Included are compositions, and methods of making, coated controlled-release drug and ion exchange resin form complexes. Methacrylate coatings, which can be free of plasticizers particularly with Eudragit® NE type polymer, are preferred to enhance the control of drug release from the drug-resin complexes. Liquid formulations including the coated resin forms and a chelating agent to inhibit degradation are also included.
