Innovative approaches to drug screening—such as evaluation to identify the optimal solid state of a molecule and in-vitro characterization to establish the optimal solid state of a molecule and the ideal bioavailability-enhancing technology—can help drug developers meet accelerated development timelines while managing risk.

Prior to use in a continuous manufacturing system for oral solid dosage forms, loss-in-weight feeders need to be tested and validated to understand the performance capabilities of a given material–feeder combination. In this article, the proper strategy for set-up and optimization of a loss-in-weight feeder is demonstrated for a range of materials. The optimized set-up of the feeders was demonstrated to provide suitable performance for even the most challenging, poorly flowing materials.
