The Green Book (Guide for the use of the process analytical technology)

The Green Book, or "Guide for the Use of Process Analytical Technology," provides scientific and regulatory guidance for integrating real-time testing methods into manufacturing, particularly in the pharmaceutical industry. It helps ensure products are consistently made to quality standards by using analytical tools during production to monitor and control processes. This approach reduces reliance on end-product testing, increases efficiency, and enhances product quality. The Green Book promotes a science-based, data-driven approach, enabling manufacturers to optimize processes, improve compliance, and support innovation while maintaining rigorous quality assurance.
