Repurposing drug molecules for new pulmonary therapeutic interventions.

Drug repurposing with novel strategies has substantially contributed to the identification and analysis of new molecules for better pulmonary intervention. This review would offer insights into the drug repurposing for effective pulmonary therapy. The review begins by explaining the relevant background knowledge of drug repurposing, the need for drug repurposing, and their potential advantages in treating pulmonary diseases. This article takes into account clinical trial problems, drug delivery challenges, regulatory issues, and human ergonomics along with chemistry manufacturing and control strategies for effective pulmonary drug repurposing. This article elaborates on pulmonary drug repurposing with help of strengths, weaknesses, opportunities, and threat analysis. In brief, this article is the first inclusive account of drug repurposing for better pulmonary therapy. Graphical abstract.
