Abstract
The technology of dry powder inhalers has often surpassed our scientific understanding of the mechanisms of formulation, aerosol performance, and manufacture controls for these devices. However, with greater research effort being devoted to these systems, the science is beginning to drive the technological innovation. In this chapter, dry powder inhaler technology is discussed in relation to this growing body of scientific understanding. In addition, a section on the practical implications, most notably on manufacturing of these systems, is also included.
