Figure 1

The de-aggregation process that occurs in a dry powder inhaler (DPI) during an inhalation. This example shows how the interaction between the patient's inhalation and the resistance of the inhaler generates the turbulent energy to split the small drug particles from their larger carrier (in this case lactose) particles.
