Croscarmellose sodium is a commonly used pharmaceutical additive approved by the US Food and Drug Administration (FDA). Croscarmellose sodium is used in injectable preparations as a suspending agent to promote solubilization of compounds with poor water solubility. Croscarmellose sodium is also present in tablets as binder, glidant and antiadherent, in bulk laxatives as active principle and as an additive in food products. Croscarmellose sodium can be used as an excipient, such as excipients, disintegrants, aids in disintegration. 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].
