In-vitro and Particle Image Velocimetry Studies of Dry Powder Inhalers [PDF]
Int J Pharm 592 (2021) p.119966, 2021 Inhalation drug delivery has seen a swift rise in the use of dry powder inhalers (DPIs) to treat chronic respiratory conditions. However, universal adoption of DPIs has been restrained due to their low efficiencies and significant drug losses in the mouth-throat region. Aerosol efficiency of DPIs is closely related to the fluid-dynamics characteristics
