Real-time NIR monitoring of pharmaceutical blending processes with multivariate quantitative models

Issue 5 2009, Past issues / 9 October 2009 /

Process analytical technology (PAT) initiatives are now an integral part of developmental efforts in the pharmaceutical industry. Many technical and scientific papers and even dedicated sections appear regularly in several pharmaceutical manufacturing publications. They may be part of a quality by design (QbD) project to better identify and understand critical process parameters. The need and plus value of PAT is usually well-recognised and understood through establishment of the design space of a unit process. However, monitoring and control methodology and PAT protocols are still undefined, and there is no global consensus yet. It is on these grounds that ASTM started working groups focusing on the elaboration of standards in model building and process monitoring with PAT.

QbD and PAT: From Science to Compliance

Issue 4 2009, Past issues / 30 July 2009 /

Boards of health like the Food and Drug Administration and European Medicines Agency and ICH guidelines Q8, Q9 and Q10, provide a framework for Quality by Design (QbD) that fully integrates drug substance and drug product development with the principles of Quality Risk Management (QRM), Process Analytical Technology (PAT) and Quality Systems (QS). QbD may begin as early as drug substance engineering and could extend to formulation and process development.

Key Aspects to a Successful Implementation in Pharmaceutical Manufacturing

Issue 5 2008, Past issues / 29 September 2008 /

The use of Process Analytical Technology (PAT) while a relatively new concept to the Pharmaceutical Industry has been a tried and tested concept in the petrochemical industry for many years. The adaptation of PAT systems by the Pharmaceutical Industry was accelerated by the recent initiatives of the regulatory authorities globally to modernize the Pharmaceutical Industry and focus on enhancing product quality. The common theme of the various initiatives is “planning for quality,” (i.e.) building quality into the products as compared to the traditional paradigm of testing the product to ensure quality.

Is the pharmaceutical manufacturing environment of today becoming more challenging? There is increasing pressure to control or reduce costs because of the limitations on healthcare budgets. Asset utilisation, operating efficiencies and cycle times in the pharmaceutical industry generally compare unfavourably with other high technology industries. Despite the resources invested in compliance, many companies continue to struggle to meet the regulatory requirements, as evidenced by warning letters and consent decrees.
