Description

In Vitro

Dipotassium hydrogen phosphate trihydrate affects pH level in liquid. Dipotassium hydrogen phosphate (trihydrate) can be used as an excipient, such as pH regulator, buffer. 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].
