Ethyl acrylate-methyl methacrylate copolymer

Ethyl acrylate-methyl methacrylate copolymer can be used as an excipient, such as sustained-release coating materials, matrix sustained-release tablet binders and retarders. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs[1].
