New Trends in Formulations for Oral Inhalation

Inhalation is a promising, noninvasive method of delivering active pharmaceutical ingredients to the lungs. It can achieve high local and systemic concentrations in a short amount of time. However, oral inhalation poses problems as well. Formulating some drugs in high enough amounts, delivering large molecules as stable aerosols, and generating particles of the optimal size (1-5 µm) are challenges. This Collection is interested in tools that may improve the success of orally inhaled formulations in clinics, including new drug particles, targeted delivery approaches, fixed dose combinations, and innovative carriers or drug delivery techniques.
