Dipotassium hydrogen phosphate is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. Dipotassium hydrogen phosphate 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.
