Bioactivity Calcium hydrogen phosphate dihydrate, also known as CHPD or DCPD.Calcium hydrogen phosphate dihydrate can be found quite frequently in urinary calculi stones. Calcium hydrogen phosphate dihydrate can be used as an excipient, such as diluent, adsorbent. 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].
