| Bioactivity | Poly(acrylic acid) inhibits the corrosion of pure cast aluminium in the acid medium by adsorption onto the metal surface. Poly(acrylic acid) can be used as an excipient, such as coating material, release blocker. 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][2]. |
