The aerosolisation performances of dry powder inhaler (DPI) systems have been concisely reviewed, focusing on the composite interactions that exist in this kind of complex systems between cohesive and adhesive forces. Furthermore, the influence of the inhalation device design on the performance of the powder formulation has been evaluated. In summary, how the specific properties of formulation components are directly linked to aerosolisation performance of DPI systems is highlighted in this article.
- Dry powder inhalation
- Engineered composites
- Active pharmaceutical ingredient
