Nano Science in Pulmonary Drug Delivery

Respiratory diseases are a common disease with high incidence all over the world, pose a serious threat to human health and are considered to be an economic and social burden. The application of nanotechnology in drug delivery systems has created new treatments for respiratory diseases. In this regard, this review has systematically introduced the physicochemical properties of nanoparticles (NP). We have reviewed the current state of research on various Nano carriers in the treatment of respiratory diseases, including liposomes, solid lipid Nano carriers, and polymer Nano carriers. The application of nanotechnology overcomes some of the deficiencies inherent in drugs and offers endless possibilities for the development of drugs for the treatment of respiratory diseases. However, most of the relevant research is in the preclinical stage and the assessment of safety remains a difficult task. Future research is needed to focus on changes in the performance, molecular mechanisms, and potential toxicity of therapeutic Nano medicines.
