Pre-prescription studies are an important prerequisite for the development of formulation prescribing process, which provides an important basis for the assessment of the drug-forming properties of compounds, the route of administration and dosage form selection of products, the design of prescribing process and quality control, and is a solid foundation for the development of safe, effective and quality-controlled drugs. Pre-prescription formulation analysis is the analysis of the physical and chemical properties of a drug when used alone or in combination with excipients. Early prediction of these properties will yield information useful to formulators in developing stable and safe dosage forms with good bioavailability.
