Abstract
Granulation of microcrystalline cellulose with a granulating fluid consisting of water and a water-miscible, volatile, polar organic solvent yields porous granules which are comprised of particles that are larger than the ungranulated microcrystalline cellulose. This granulated microcrystalline cellulose is capable of cushioning controlled release particles and barrier coated particles from the compression forces used in tableting, thereby maintaining the physical integrity of the components of the tablet.
