The invention relates to medicine, in particular to gastroenterology, and lies in the field of treatment of liver diseases of various origins. For this purpose, the hepatoprotective agent that is introduced to the patient is embodied as derivatives of bis(2-thio-4,6-dioxo-1,2,3,4,5,6-hexahydropyrimidine-5-yl)arylmethanes. The method provides reduction of the manifestations of cytolysis under the influence of damaging agents and a statistically significant reduction of dysproteinemia, it accelerates restoration of detoxifying processes of the liver, increases induction of endogenic interferon alfa and, consequently, makes the protection of liver cells during hepatitides of various origins more effective.
