In pharmaceutical formulations a functional polymer is simply a polymeric material that performs an excipient function. These can include ion exchange resins, polymeric adsorbents, cellulosic polymers (disintegrants, matrix formers etc), and polymeric coatings (e.g. Eudragit® coatings). Ion exchange resins in particular are multifunctional, providing functions such as extended release, tablet disintegration, taste masking, and improved physical and chemical stability.
