A Review on Process Analytical Technology (PAT) In Pharmaceutical Manufacturing

Process Analytical Technology (PAT) is an advanced scientific toolset introduced to improve and optimize pharmaceutical manufacturing. It facilitates real-time monitoring and control of key parameters to ensure consistent product quality throughout the production process. Unlike traditional end-product testing, PAT emphasizes a proactive approach, integrating technologies like spectroscopic sensors, multivariate analysis, and automated control systems. This article outlines the fundamentals of PAT, its applications across various manufacturing stages, benefits, challenges, regulatory aspects, and future perspectives. By leveraging PAT, pharmaceutical industries achieve better process understanding, improved efficiency, and compliance with global quality standards.
