[The use of viral RNA polymerase inhibitors in combination with a fusion inhibitor in the treatment of patients with COVID-19: hypothesis].

This review article considers the possibilities of combined antiviral therapy in the treatment of patients with COVID-19, based on the analysis of the mechanism of action of known antiviral drugs in the framework of the medical hypothesis. The potential effectiveness of the joint use of viral RNA polymerase inhibitors and a fusion inhibitor in this pathology is discussed. The review discusses the main representatives of these groups of drugs - ribavirin, riamilovir, umifenovir, favipiravir. The efficacy and safety profile of these drugs was analyzed, including the experience of their use in clinical trials conducted during the COVID-19 pandemic, as well as earlier work performed during the SARS and MERS epidemics.
