The goal of PAT is to understand and control the manufacturing process, which is consistent with our current drug quality system: quality cannot be tested into products; it should be built-in or should be by design.
|Process Analytical Technology is: |
It is important to note that the term analytical in PAT is viewed broadly to include chemical, physical, microbiological, mathematical, and risk analysis conducted in an integrated manner.
Process Analytical Technology tools:
There are many current and new tools available that enable scientific, risk-managed pharmaceutical development, manufacture, and quality assurance. These tools, when used within a system can provide effective and efficient means for acquiring information to facilitate process understanding, develop risk-mitigation strategies, achieve continuous improvement, and share information and knowledge. In the PAT framework, these tools can be categorized as:
An appropriate combination of some, or all, of these tools may be applicable to a single-unit operation, or to an entire manufacturing process and its quality assurance.
A desired goal of the PAT framework is to design and develop processes that can consistently ensure a predefined quality at the end of the manufacturing process. Such procedures would be consistent with the basic tenet of quality by design and could reduce risks to quality and regulatory concerns while improving efficiency. Gains in quality, safety and/or efficiency will vary depending on the product and are likely to come from:
- Reducing production cycle times by using on-, in-, and/or at-line measurements and controls.
- Preventing rejects, scrap, and re-processing.
- Considering the possibility of real time release.
- Increasing automation to improve operator safety and reduce human error.
- Facilitating continuous processing to improve efficiency and manage variability
- Using small-scale equipment (to eliminate certain scale-up issues) and dedicated manufacturing facilities.
- Improving energy and material use and increasing capacity.
|To support Process Analytical Technology activities, FDA created: |
- "Sunrise School." A sunrise school was established for continuing education to foster in-depth discussions and understanding of various multivariate data analysis techniques.
- Journal Club. The Journal Club discusses articles and research relating to the implementation and development of systems and methods for PAT applications.
- Training Program. A training program was established for the PAT Team members who will manage the review/inspection process. This program was developed in coordination with several academic centers of excellence and includes didactic sessions, as well as advanced on-site practicums.
