Using online mass spectrometry to predict the end point during drying of pharmaceutical products
Contributor(s):: Dodda, Aditya G., Saranteas, Kostas, Henson, Michael A.
Drying of active pharmaceutical ingredients (APIs) is an energy-intensive process that is often a manufacturing bottleneck due to the relatively long processing times. A key objective is the ability to determine the drying end point, the time at which all solvent has been evaporated from the...

System-wide hybrid MPC–PID control of a continuous pharmaceutical tablet manufacturing process via direct compaction
Contributor(s):: Singh, Ravendra, Ierapetritou, Marianthi, Ramachandran, Rohit
The next generation of QbD based pharmaceutical products will be manufactured through continuous processing. This will allow the integration of online/inline monitoring tools, coupled with an efficient advanced model-based feedback control systems, to achieve precise control of process variables,...

Real time monitoring of powder blend bulk density for coupled feed-forward/feed-back control of a continuous direct compaction tablet manufacturing process
Contributor(s):: Singh, Ravendra, Román-Ospino, Andrés D. Romañach, Rodolfo J. Ierapetritou, Marianthi, Ramachandran, Rohit
The pharmaceutical industry is strictly regulated, where precise and accurate control of the end product quality is necessary to ensure the effectiveness of the drug products. For such control, the process and raw materials variability ideally need to be fed-forward in real time into an automatic...

Monitoring ibuprofen–nicotinamide cocrystal formation during solvent free continuous cocrystallization (SFCC) using near infrared spectroscopy as a PAT tool
Contributor(s):: Kelly, A.L., Gough, T., Dhumal, R.S., Halsey, S.A., Paradkar, A.
The purpose of this work was to explore NIR spectroscopy as a PAT tool to monitor the formation of ibuprofen and nicotinamide cocrystals during extrusion based solvent free continuous cocrystallization (SFCC). Drug and co-former were gravimetrically fed into a heated co-rotating twin screw...
