COVID-19: Nitric oxide shows promise as antiviral treatment

An in vitro study finds that nitric oxide may suppress SARS-CoV-2, the virus that causes COVID-19. The researchers suggest that inhaled nitric oxide may be an effective treatment for the disease.

The molecule has anti-inflammatory effects and is a vasodilator, meaning it dilates blood vessels to increase blood flow. It also has antiviral properties.

Previous studies show that nitric oxide is effective against the herpes viruscoxsackievirus, and hantavirusTrusted Source.

According to a 2005 in vitro study involving cell cultures grown in the lab, it also inhibits the replication of SARS-CoV. Closely related to SARS-CoV-2, this coronavirus caused the global outbreak of Severe Acute Respiratory Syndrome (SARS) in 2003.
