Abstract
In any industrial pharmaceutical process, inherent minor variations in raw materials and process parameters can lead to variability in the quality of the final product. Process Analytical Technology (PAT) addresses this issue by using sensors to monitor production in real time. However, modern complex manufacturing, particularly for biopharmaceuticals, generates more data than traditional PAT methods can effectively process. Artificial intelligence (AI) complements PAT by adding advanced technologies such as Machine Learning, Artificial Neural Network and Deep Learning. This combination allows continuous quality monitoring, early anomaly detection, and adaptive process control. This article presents the results of a comprehensive review of scientific articles that demonstrates successful applications of AI-enhanced PAT systems utilizing near-infrared spectroscopy, Raman spectroscopy, and advanced imaging for quality attribute monitoring in both solid dosage forms and biopharmaceutical products. Together, AI and PAT enable a smarter manufacturing approach that enhances drug quality and safety while reducing process variability and production downtime. This integrated approach represents a significant advancement in pharmaceutical production, facilitating the implementation of Quality by Design and continuous manufacturing.
