Study Notes
Size Reduction
- Size reduction involves producing smaller mass units from larger mass units of the same material.
Importance of Size Reduction in Pharmacy
- Size reduction enhances rates of: • dissolution • chemical reaction • mixing • extraction • drying • absorption
- This enhancement occurs in: • oral administration • topical application • parenteral administration
Theory of Size Reduction
- When a single particle is subjected to sudden impact and fractured, it yields: • few relatively large particles • a number of fine particles • relatively few particles of intermediate size
- If the energy of the impact is increased: • larger particles become smaller and more numerous • the number of fine particles increases appreciably, but their size does not change greatly
- The size of finer particles relates to the internal structure of the material
- The size of larger particles relates to the energy of impact
