WHAT are sampling errors-and WHAT can we do about them? Part 1
Contributor(s):: Romañach, Rodolfo J., Joubert Castro, Aidalu, Esbensen, Kim H
The objective of this column is to provide easy-to-understand examples of sampling errors. Prompted by recent participationsand presentations at on-line conferences and meetings, we believe there is a need for a more fulfilling introduction andexemplification of the concept and real-world...

Pharmaceutical manufacturing and the quality by design (QBD), process analytical technology (PAT) approach
Contributor(s):: Murphy, Trevor, O’ Mahony, Niall, Panduru, Krishna, Riordan, Daniel, Walsh, Joseph
This paper is the result of a literature review focusing on the application of process analytical technology (PAT) for the pharmaceutical industry in conjunction with the quality by design (QBD) framework. PAT and the QBD framework put forward by the FDA, offer a holistic approach to...

Non-invasive, continuous, quantitative detection of powder level and mass holdup in a metal feed tube
Contributor(s):: Louge, Michel Y, Mandur, Jasdeep, Blincoe, William, Tantuccio, Anthony, Meyer, Robert F
We describe a quantitative, non-invasive capacitance detector providing a rapid signal that varies continuously with powder level and/or mass holdup in the metal feed tube of a tablet press. We outline the principle of its processing electronics, provide an algorithm for the accurate...

Flexibility in Drug Product Development: A Perspective
Contributor(s):: Kapoor, Yash, Ferguson, Heidi, Skomski, Daniel, Daublain, Pierre, Troup, Gregory, Dalton, Chad, Ramasamy, Manoharan, Templeton, Allen
The process of bringing a drug to market involves innumerable decisions to refine a concept into a final product. The final product goes through extensive research and development to meet the target product profile and to obtain a product that is manufacturable at scale. Historically, this...

Continuous Twin Screw Wet Granulation and Drying - Control Strategy for Drug Product Manufacturing
Contributor(s):: Dahlgren, Gabriella, Tajarobi, Pirjo, Simone, Eric, Ricart, Brendon, Melnick, Jason, Puri, Vibha, Stanton, Courtney, Bajwa, Gurjit
The use of continuous manufacturing has been increasing within the pharmaceutical industry over the last few years. Continuous direct compression has been the focus of publications on the topic to date. The use of wet granulation can improve segregation resistance, uniformity, enhance density,...

An ontological knowledge-based system for the selection of process monitoring and analysis tools
Contributor(s):: Singh, Ravendra, Gernaey, Krist V, Gani, Rafiqul
Efficient process monitoring and analysis tools provide the means for automated supervision and control of manufacturing plants and therefore play an important role in plant safety, process control and assurance of end product quality. The availability of a large number of different process...

An automated modular assembly line for drugs in a miniaturized plant
Contributor(s):: Hu, Chuntian, Testa, Christopher, Wu, Wei, Shvedova, Khrystyna, Shen, Dongying, Sayin, Ridade, . Halkude, Bhakti, Casati, Federica, Hermant, Paul, Ramnath, Anjana, Born, Stephen, Takizawa, Bayan, O'Connor, Thomas, Yang, Xiaochuan, Ramanujamd, Sukumar, Mascia, Salvatore
We report here a fully automated, end-to-end, integrated continuous manufacturing process for a small-molecule generic medication with built-in quality assurance. The entire process fits into a box of 30.7 m2 modular footprint and a total residence time of less than 30 h, with a throughput up to...

Adequacy and Verifiability of Pharmaceutical Mixtures and Dose Units by Variographic Analysis (Theory of Sampling) - A Call for a Regulatory Paradigm Shift
Contributor(s):: Esbensen, Kim H, Román-Ospino, Andrés D., Sanchez, Adriluz, Romañach, Rodolfo J.
In spite of intense efforts in the last 20 years, the current state of affairs regarding evaluation of adequacy of pharmaceutical mixing is at an impressive standstill, characterized by two draft guidances, one withdrawn, and the other never approved. We here analyze the regulatory, scientific...

Achieving Continuous Manufacturing for Final Dosage Formation: Challenges and How to Meet Them
Contributor(s):: Byrn, Stephen, Futran, Maricio, Thomas, Hayden, Jayjock, Eric, Maron, Nicola, Meyer, Robert F., Myerson, Allan S., Thien, Michael P., Trout, Bernhardt L.
We describe the key issues and possibilities for continuous final dosage formation, otherwise known as downstream processing or drug product manufacturing. A distinction is made between heterogeneous processing and homogeneous processing, the latter of which is expected to add more value to...
