Twin-screw granulation and high-shear granulation: The influence of mannitol grade on granule and tablet properties
Contributor(s):: Megarry, Andrew, Taylor, Agnes, Gholami, Aida, Wikstrom, Hakan, Tajarobi, Pirjo
Granule structure has a key influence on tablet critical quality attributes. The ability to control this structure through excipient choice is an important part of formulation development. Mannitol is a popular diluent and the choice of input grade has been shown to impact granule properties....

Robust State Estimation of Feeding-Blending Systems in Continuous Pharmaceutical Manufacturing
Contributor(s):: Liu, Jianfeng, Su, Qinglin, Moreno, Mariana, Laird, Carl, Nagy, Zoltan, Reklaitis, Gintaras
State estimation is a fundamental part of monitoring, control, and real-time optimization in continuous pharmaceutical manufacturing. For nonlinear dynamic systems with hard constraints, moving horizon estimation (MHE) can estimate the current state by solving a well-defined optimization problem...

Characterization of NIR interfaces for the feeding and in-line monitoring of a continuous granulation process
Contributor(s):: Román-Ospino, Andrés D, Tamrakar, Ashutosh Igne, Benoît Dimaso, Elyse Towns Airiau, Christian Clancy, Donald J Pereira, Glinka Muzzio, Fernando J Singh, Ravendra, Ramachandran, Rohit
This work describes the characterization of three NIR interfaces intended to monitor a continuous granulation process. Two interfaces (i.e. a barrel interface and a rotating paddle interface) were evaluated to monitor the API concentration at the entrance of the granulator, and a third interface...
