PEG1000 can be utilized as a pharmaceutical excipient in applications such as ointment bases and lubricants. Pharmaceutical excipients or adjuvants refer to chemical substances used in the pharmaceutical manufacturing process, excluding the active drug components. Generally, they are non-active constituents in drug formulations that enhance stability, solubility, and processability. Additionally, excipients can influence the absorption, distribution, metabolism, and excretion (ADME) processes during concurrent medication use.
