We want to formulate tablets after the granulation and addition of other excipients and to preserve the micronized state of the drug during the granulation.
To granulate hydrophobic drug powder, consider to use a less hydrophilic polymer solution, such as hydroxypropyl cellulose to improve wettability of the hydrophobic drug. To reduce the agglomeration of the micronized powder, one may use a carrier such as lactose and combine with spray granulation technique.
Wet granulation: PovidoneK 30 solution in water pr ethanol can be used to granulate hydrophobic drug powder, In that case longer mixing time me be needed.
Dry granulation: Mix PovidoneK 30 with drug and granulate by slugging method.
