Study Notes
- Segregation of APIs in powder blends can be reduced by careful formulation design, including selection of excipients and ordered mixing.
- Dry granulation is a technique used to improve the flowability, compactability, and prevent segregation of powder blends for oral solid dosage forms.
- Dry granulation process can be performed using roller compaction or slugging methods, with following steps: milling of APIs and excipients, blending of powder mix, compression of powder mixture into large tablets or ribbons, milling of tablets or ribbons, and mixing with lubricant and disintegrating agent.
- Dry granulation is suitable for APIs that are sensitive to solvents, heat, and moisture, and is more cost-effective than wet granulation due to fewer required steps.
- Wet granulation is another common method for manufacturing oral solid dosage forms, which involves wet massing of API and excipients with a granulation liquid (with or without polymeric binder), followed by wet sizing and drying, with following steps: milling of APIs and excipients, mixing of powder mix, agglomeration of solution binder with powder mix, drying of moist granules, milling of dry granules, and mixing of screened granules.
- Wet granulation is suitable for handling fine or dusty powders, improving the compressibility of powders, and preventing segregation of APIs, as well as improving the dissolution of hydrophobic drugs.
- However, wet granulation requires many expensive equipments and a large space due to multiple unit operations, and is a time-consuming and complex process, especially during the drying phase.
- Wet granulation is not suitable for moisture and heat sensitive APIs.
- Both dry and wet granulation methods require feeders for continuous manufacturing.
