Objectives of size reduction Size reduction leads to increase of surface area. Pharmaceutical capsules, insufflations ( powders inhaled directly into the lungs), suppositories and ointments require particles size to be below 60 mm size. To increase the therapeutic effectiveness of certain drugs by reducing the particle size. Size reduction produces particles in narrow size range.
