   In pharmaceutical manufacturing of solid formulations, blending with a lubricant is a key process in preventing sticking during compression. Sticking not only results in tablets with a disfigured appearance but also brings about the interruption of continuous operations. The aim of our study was...

   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...
