Research on the stability of pharmaceutical preparations provides a scientific basis for the determination of production, packaging, storage, transportation conditions and the validity period of pharmaceutical products. This is achieved by investigating the parameters of the changes of API properties and preparations with time under the influence of temperature, humidity and light, so as to ensure the safety and effectiveness of clinical medication. Stability evaluation is one of the main components of drug quality control research. It is closely related to drug quality research and the establishment of quality standards.
The research on preparation stability is featured by phases and links all steps in drug R&D.

FAQ
What is Stability of a Drug?
Stability of a drug refers to the degree to which the physical, chemical, biological and microbial properties of an active substance or formulation can be maintained within prescribed limits during its entire storage and use.
