Addressing Segregation of a Low-Dosage Direct Blend
The authors modified equipment and the manufacturing process to re-establish content uniformity among tablets.

Results and conclusion


Figure 4: Stratified tablet content-uniformity data for (a) demonstration batch #1 with segregation and (b) demonstration batch #2 after process and equipment modifications. (ALL FIGURES ARE COURTESY OF THE AUTHORS)
The process and equipment modifications implemented for the second demonstration batch were successful in reducing the CU variation and alleviating the upward CU trend that was observed at the end of compression in the first demonstration batch, as shown in Figure 4. The CU data for the second demonstration batch showed minimal variation (RSD = 0.9%, n = 60 samples) and met the FDA draft guidance specifications. The successful validation of the commercial process further demonstrated the robustness of these modifications.
