Total and regional airway deposition of orally inhaled drugs is determined by the complex interaction of numerous patient- and inhaler-related factors. Particle size (aerodynamic diameter) is considered to be the most important of the aerosol-related factors(1–3); however, the medical literature lacks standard nomenclature to distinguish aerosol particle sizes. There are clear differences in particle behavior and deposition according to size, and hence we believe a strong rationale for clearly denoting the aerosol particle size of orally inhaled, therapeutic aerosols, both in product descriptions and as part of the design and reporting of research in this area
