Impact of surface roughness of pre-treated punches and powder properties on prevention of sticking during pharmaceutical tableting
Contributor(s):: Takeuchi, Y, Murase, YTahara, K, Takeuchi, H
In the present study, surface-modified punches with different roughness were evaluated for their ability to prevent sticking during pharmaceutical tableting using a single punch machine. The surface roughness of the punch faces was assessed using a laser microscope. Acetaminophen and ibuprofen...

Direct compaction: An update of materials, trouble-shooting, and application
Contributor(s):: Li, Z, Zhao, LJLin, X, Shen, L, Feng, Y
Direct compaction (DC) is the preferred choice for tablet manufacturing; however, only less than 20% of active pharmaceutical ingredients could be compacted via DC as its high requirement for functional properties of materials. Materials with improper functionalities could lead to serious...
