Formulation Stability Study

Research on the stability of pharmaceutical preparations provides scientific basis for the determination of production, packaging, storage, transportation conditions and validity period of pharmaceutical products by investigating the laws of the changes of the properties of APIs and preparations with time under the influence of temperature, humidity and light, so as to ensure the safety and effectiveness of clinical medication. Stability study is one of the main contents of drug quality control research. It is closely related to drug quality research and the establishment of quality standards.
