Disodium phosphate, also known as Na2HPO4, is used to regulate the pH of liquids. Disodium phosphate can be used as an excipient, such as a buffer, chelating agent, etc. Pharmaceutical excipients, also known as medicinal excipients, refer to other chemical substances used in the pharmaceutical process, in addition to pharmaceutical ingredients. Pharmaceutical excipients generally refer to non active ingredients in pharmaceutical preparations, which can improve the stability, solubility, and processability of pharmaceutical preparations. Pharmaceutical excipients can also affect the absorption, distribution, metabolism, and elimination (ADME) process of co administered drugs.
