Stability Studies (ICH Guidelines) Laboratory Testing Services
Standard-Related Information
Stability studies are an essential aspect of ensuring the quality and safety of pharmaceutical products. These studies involve testing the physical and chemical stability of drugs under various conditions, such as temperature, humidity, and light exposure. The International Conference on Harmonisation (ICH) guidelines provide a framework for conducting these studies.
Overview of Relevant Standards
Several standards govern the conduct of stability studies:
International and National Standards
The following standards are relevant to stability studies:
Standard Title
