FIELD: medicine; pharmaceuticals.

SUBSTANCE: group of inventions relates to pharmaceutics and medicine, specifically to a pharmaceutical composition and a method of treating a disease caused by exposure to a virus whose genome is encoded by a single-stranded RNA suture and which uses viral RNA-dependent-RNA polymerase for its replication. Disclosed composition contains favipiravir and darunavir in a weight ratio of favipiravir:darunavir equal to 1:1. Composition can additionally contain a zinc compound. Composition can be in solid or liquid form. Method of treating involves administering the above pharmaceutical composition to a subject in need thereof.

EFFECT: darunavir and favipiraviir combined use of said ratio leads to a significant increase in the mutual effect on viruses whose genome is encoded by a single-stranded RNA suture and which use viral RNA-dependent-RNA polymerase for their replication, with no additional side effects.
