Fluticasone propionate as a potential treatment for COVID-19

Outpatient treatment options for mild to moderate COVID-19 are severely limited. While many therapeutic options have been proposed, very few have demonstrated the appropriate safety and efficacy to warrant approval by national or international regulatory bodies. Monoclonal antibodies have been shown to decrease hospitalization in high-risk patients, but use remains limited due to challenges associated with both production and administration, and other treatment options are urgently needed. The anti-inflammatory drug fluticasone propionate has recently emerged as a potential outpatient treatment option, especially for those with newly diagnosed disease. This manuscript reviews what is known about fluticasone and looks ahead to examine how the drug may be used in the future to address the COVID-19 pandemic.
