Exploring a Modern Control Strategy for Wurster Coating
A process control system based on PAT can compensate for variations in particle size, resulting in more consistent coating thickness in a Wurster coating process.
Predicting Multiparticulate Dissolution in Real Time for Modified- and Extended- Release Formulations
Process analytical technology, based on monitoring particle size distribution and tracking coating thickness measurements in real time, can be used to predict the dissolution of polymer-coated multiparticulates.
