1. research on pharmaceutical preparations: the crystal form of drugs has great influence on their physical and chemical properties, stability, bioavailability and curative effect. By studying the crystal forms of drugs, the preparation process of drugs can be optimized and the stability and bioavailability of drugs can be improved.
2. Study on solid state: The crystal form of solid drugs is an important indicator of its solid state. By studying the crystal forms of drugs, we can know the crystal forms, crystal structures, lattice parameters and other information of drugs, which is helpful to study the solid phase transition, solubility, dissolution kinetics and other characteristics of drugs.
3. Study on crystallization process: The crystallization process of drugs refers to the process of crystallizing drugs in solution into solid crystals by controlling conditions such as temperature, concentration and pH value in a specific crystallization environment. By studying the crystallization process, the crystallization conditions of drugs can be optimized, and the crystallization yield, crystallization rate and crystal purity can be improved, thus improving the preparation technology and quality of drugs.
In a word, the application of the original patent registration crystallization mainly includes the study of pharmaceutical preparations, the study of solid state and the study of crystallization process. It is of great significance for drug research and development and preparation process optimization.
