ION EXCHANGE RESINS AND APPLICATIONS IN PHARMACEUTICAL TECHNOLOGY
ABSTRACT
Ion exchange resins (IER) are cross-linked, water insoluble polymers carrying ionizable functional
groups on their repeating positions. They are considered as safe materials due to their insoluble and
nonabsorbable nature. This advantage made IER subject of several research in different areas of
pharmaceutical technology such as oral sustained release, taste masking, rapid dissolution, stability
enhancement and also they are used for their therapeutic activity since the middle of 20th century. This
review discussed the general properties of IER and their novel applications in the area of
pharmaceutical technology.
