Nebulized inhalation drug delivery: clinical applications and advancements in research

Abstract

Nebulized inhalation administration refers to the dispersion of drugs into small droplets suspended in the gas through a nebulized device, which are deposited in the respiratory tract by inhalation, to achieve the local therapeutic effect of the respiratory tract. Compared with other drug delivery methods, nebulized inhalation has the advantages of fast effect, high local drug concentration, less dosage, convenient application and less systemic adverse reactions, and has become one of the main drug delivery methods for the treatment of respiratory diseases. In this review, we first discuss the characteristics of nebulized inhalation, including its principles and influencing factors. Next, we compare the advantages and disadvantages of different types of nebulizers. Finally, we explore the clinical applications and recent research developments of nebulized inhalation therapy. By delving into these aspects, we aim to gain a deeper understanding of its pivotal role in contemporary medical treatment.
