Applying PAT in pharmaceutical processes

As cited by the FDA, “Process Analytical Technology (PAT) is a system for designing, analysing, and controlling manufacturing through timely measurements (i.e., during processing) of critical quality and performance attributes of raw and in-process materials and processes with the goal of ensuring final product quality.”1 The main goal of PAT is to gain a deep understanding of manufacturing processes and to learn how to control them1. When processes are understood, opportunities for continuous improvement (quality and efficiency), cycle time reduction, cost reduction and QC lab test replacement arise. In this article, the strategy of Johnson & Johnson Pharmaceutical Research & Development (J&J PRD) towards the implementation of PAT in Pharmaceutical Process Development is explained and elucidated by case studies.

Applying PAT in Chemical Process Development

Issue 3 2009, Past issues / 29 May 2009 /

As the time-to-market of pharmaceutical products has elongated, while its prices are under big pressure, cost saving is currently essential in the pharmaceutical industry.

PAT: not a purpose in itself

Issue 2 2008, Past issues / 19 March 2008 /

The process analytical technology guidelines have been a hotly debated topic within the pharmaceutical industry ever since they were made public in 2004. This also holds true at Johnson & Johnson Pharmaceutical Research & Development (J&JPRD), Division of Janssen Pharmaceutical N.V. In recent years, the company has introduced PAT tools in its manufacturing operations and in its development organisation on a project-by-project basis. Several of these projects have resulted in a better insight into critical manufacturing processes and have led to significant optimisations.
