A modular toolbox enables residence time distribution-based control for continuous pharmaceutical manufacturing.

In continuous pharmaceutical manufacturing, real-time assurance of critical quality attributes (CQAs) is highly desired. Among CQAs, control and assurance of tablet potency has been challenging due to lack of real-time measurement sensors tied to optimization programs. A modular self-contained toolbox developed using Python programming has been demonstrated to predict tablet potency based on a residence time distribution (RTD) model and apply a diversion strategy to divert out-of-specification tablets. The modular toolbox can be integrated with any commercially available tools to control tablet potency, can automatically calibrate the RTD model for different formulations and processes, and can be used to predict outlet concentrations, assuming accurately quantified inputs.
