Design Principles
"The performance of a dry powder inhaler is a function of both the device and the powder formulation; optimizing particle properties is key to maximizing drug delivery."
The effectiveness of dry powder inhalers (DPIs) is heavily dependent on how well the powder disperses into an aerosol that can be inhaled deep into the lungs. By understanding and manipulating particle size, shape, and surface characteristics, designers can significantly improve drug delivery and patient outcomes.
What This Means for Your Design
