Abstract:
Controlled release solid oral dosage forms have been widely used for decades, enabling drugs to be administered more comfortably while at the same time providing a sustained and reproducible method of release. (Meth)acrylate copolymers are one of the options available when considering a sustained release solid form. Due to their different functionalities it is possible to achieve various different release profiles. The electrical character of these copolymers and their pH-dependent solubility can result in new and modified patterns when these polymers are combined. This review sheds light on various studies involving combinations of (meth)acrylate copolymers for use in multi-unit systems and matrix tablets, and also on several analytical methods that help to identify possible interactions between these polymers.
