Process Analytical Technology for Pharmaceutical Freeze-Drying [9783527354658]

Overview

Comprehensive insights into process analytical technology for pharmaceutical freeze-drying

Process Analytical Technology for Pharmaceutical Freeze-Drying provides a comprehensive and forward-looking overview of monitoring and control strategies for one of the pharmaceutical industry’s most technically demanding manufacturing processes. Combining scientific fundamentals with industrial case studies, the book examines both established and emerging technologies used to improve process understanding, optimise cycle design, and ensure consistent product quality.

Coverage includes the measurement and interpretation of critical process variables such as temperature and pressure, wireless sensing technologies, pressure-rise methods (MTM, PRA, DPE), tunable diode laser absorption spectroscopy (TDLAS), near-infrared (NIR) and Raman spectroscopy, infrared thermal imaging, and advanced data analysis approaches. Dedicated chapters also explore through-vial impedance spectroscopy (TVIS) as a non-invasive technology for real-time monitoring of product temperature, ice mass, sublimation behaviour, and phase transitions.

The book further discusses innovations in continuous and alternative freeze-drying platforms, controlled nucleation technologies, multiplexed PAT systems, and the growing role of artificial intelligence and model-based control strategies in pharmaceutical manufacturing.
