Introduction. In modern conditions, caused by the pandemic of a new type of viral infection Covid 19, the use of paracetamol, which has hepatotoxic properties in overdose, has increased. It seems relevant to study metabolic disorders in the liver in acute paracetamol intoxication and evaluate the effectiveness of the timely use of hepatoprotective drugs. The purpose of this study is an experimental assessment of metabolic changes at the early stages of paracetamol exposure and pharmacological correction of toxic liver lesions with oxymethyluracil in comparison with known hepatoprotectors - ademetionine and Mexidol. Material and methods. Acute intragastric administration of paracetamol to laboratory animals was performed, and the corrective effect of the drug oxymethyluracil was studied in comparison with “Heptor” and “Mexidol”. Biochemical studies of biomaterial of laboratory animals were conducted. Results. The analysis found the use of known hepatoprotectors and oxymethyluracil after exposure to paracetamol to normalize the biochemical parameters that characterize the functional state of the liver in laboratory animals. Conclusion. Oxymethyluracil, along with known hepatoprotectors, has a protective effect on the liver of laboratory animals under acute exposure to paracetamol comparable to, and in some cases exceeding, the corrective action of “Heptor” and “Mexidol”.
