Furosemide is a safe, inexpensive, well-studied small molecule which is a reasonably potent inhibitor of IL-6 and TNF-α and may be administered locally to the lungs; pre-clinical data from in silico and in vitro experiments suggest that it may be a candidate for repurposing as an inhaled therapy against the immunopathologies of COVID-19. This evidence concerns the gene IL6 and COVID-19.
