Regulatory Guidelines for Continuous Monitoring Systems in Stability Storage
Stability data underpins product shelf-life and storage instructions on labels. Even short-term excursions in temperature or humidity may invalidate data or trigger batch investigations. Global regulatory agencies including the EMA and USFDA mandate real-time environmental monitoring in GMP environments to ensure:
