### Wet Granulation Process : Pharmaceutical Guidelines

Wet granulation involves the massing of a mix of dry primary powder particles using a granulating fluid.The fluid contains a solvent which can be removed by drying, and should be nontoxic.Typical solvents include water, ethanol and isopropanol and methylene chloride either alone or in combination. The granulation liquid may be used alone or, more usually, as a solvent containing a dissolved
