Chemical engineering methodology can be effectively used to solve problems of physiology, pharmacology, and medicine. Here, we present selected examples of such applications, focusing on numerical and experimental investigations of aerosol generation in inhalers of different types (e.g., dry powder inhalers, nebulizers) and particle dynamics during inhalation and drug deposition in different parts of the respiratory system. It is demonstrated how such an analysis helps to design more effective inhalers and pharmaceutical formulations for targeted and personalized drug delivery. Future directions of aerosol therapy with a potential input of chemical engineering are also proposed.
