## Abstract

The invention relates to pharmacology and can be used for treating liver diseases of various etiologies, inter alia, in combination with other preparations. Claimed is a drug with hepatoprotective activity comprised of 3-(4-bromophenyl)-6,6-dihydroxy-5-hydroxyiminohexahydro-2,4-pyrimidinedione and salts thereof of general formula (I), where X is selected from the group: H, Na, K, or from the group of hydroxyalkylammonia derivatives of general formula (II), where R1, R2 are selected from the group: H, CH3, CH2CH3, CH2CH2OH; R3 is selected from the group: H, CH2OH; and n=1, 2; the drug can be prepared in the form of tablets or capsules for enteral administration; or in the form of a liquid or lyophilized substance for parenteral administration; or in the form of rectal suppositories; or in the form of capsules or tablets, or sweets for sucking; and may additionally contain the hepatoprotector Heptral; or the hepatoprotector Essentiale; or the hepatoprotector ursodeoxycholic acid. This increases the effectiveness of a drug with hepatoprotective activity.
