Dry Powder Inhaler Device Influence on Carrier Particle Performance

Dry powder inhalers (DPIs) are distinguished from one another by their unique device geometries, reflecting their distinct drug detachment mechanisms, which can be broadly classified into either aerodynamic or mechanical-based detachment forces. Accordingly, powder particles experience different aerodynamic and mechanical forces depending on the inhaler. However, the influence of carrier particle physical properties on the performance of DPIs...
