Used primarily as an antiviral medication, it is effective in treating certain RNA virus infections. It is most notably applied in the treatment of severe cases of COVID-19, particularly in hospitalized patients. The chemical works by inhibiting the replication of the virus, thereby reducing the viral load in the body and helping to mitigate the severity of the infection. It is administered intravenously under strict medical supervision to ensure proper dosing and to monitor for potential side effects. Its application is critical in managing outbreaks and providing a therapeutic option where vaccines may not be immediately available or effective.
