Especially when dealing with sensitive materials, process verification is a critical step to ensure consistent quality. In fact, process validation is a legally enforceable requirement in the US and EU and well as many other countries that produce pharmaceuticals.
These guidelines can be broken down into three stages:
- Process Design: Identification of critical process attributes and parameters
- Process Qualification: Evaluation of the design to confirm reproducibility and consistent quality
- Continuous Process Verification: Carried out during routine production to ensure the process remains under control
