Use of Fumed silicaAmorphous silica can be used as an excipient, such as viscosifier, suspending agent, tablet disintegrating agent, adsorbent dispersing agent as liquid in powders. 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]. |
