Impact of Different Dry and Wet Granulation Techniques on Granule and Tablet Properties: A Comparative Study.

Four granulation techniques were compared evaluating their impact on granule properties and the tablet tensile strength. A common formulation was chosen to be processed with both wet and dry granulation techniques: roll compaction/dry granulation, high-shear granulation, twin-screw granulation, and fluidized-bed granulation. The produced granules were characterized in terms of granule size distribution, X-ray powder diffraction, scanning electron microscopy, porosity, and strength.
