Personalized Manufacturing of Pharmaceuticals Using One-Pot Powder Processing Equipment

Abstract

In the production of pharmaceutical solid formulations such as tablet, the spherical crystallization method, in which crystallization and granulation are carried out simultaneously in the same system, can integrate the downstream in the pharmaceutical production process, thus enabling high efficiency in pharmaceutical manufacturing. On the other hand, process enhancement such as filtration, drying, and formulation after crystallization has been an issue. To solve this problem, we developed a one-pot processing system with hybridized powder processing operations in addition to filtration and drying functions. This desktop-sized device has a highly functional rotating spherical chamber that can handle all the processes of filtration, drying, powder mixing, and wet granulation at once. In this study, we confirmed that the suspension of fenofibrate granules prepared by the spherical crystallization method can be processed by the one-pot powder processing equipment. It was also found that the wet granulation of acetaminophen granules was possible by spraying binder from the spray nozzle in this apparatus.
