decades, the number of recorded cases of drug-induced liver injury (DILI) has increased 30-fold, which is directly related to the expansion of the drug arsenal on the pharmaceutical market. According to statistics, DILI is diagnosed in 3% of patients in Russia, whereas abroad this rate is 10–20 cases per 100,000 population. Furthermore, about 40,000 deaths due to DILI are recorded annually worldwide.</p> <p>The medical scientific community has described numerous common “culprits” of hepatotoxicity. We would like to highlight a clinical case of DILI in a 67-year-old man associated with etoricoxib use. Cyclooxygenase-2-selective non-steroidal anti-inflammatory drugs (NSAIDs) rarely affect the liver, making this case non-standard and, therefore, difficult to predict. However, the consequences of NSAID-induced liver damage are often serious: fulminant hepatic failure and hepatorenal syndrome. In this regard, only a physician’s vigilant attention to the drugs taken by the patient, as well as the ability to recognize drug-induced conditions using diagnostic tests as early as possible, can stop a prolonged, asymptomatic, life-threatening toxic process.</p> <p><bold>CASE DESCRIPTION: </bold>This article describes a clinical case of DILI in a 67-year-old man associated with etoricoxib use. On the morning of the second day of planned hospitalization for blood pressure adjustment, the patient began to complain of weakness and epigastric pain. A detailed physical examination revealed icteric sclera. The therapeutic approach included laboratory tests, differential diagnosis, and therapeutic measures. After the diagnosis of DILI was established, the causative drug was discontinued and adequate therapy was administered, leading to an improvement in laboratory parameters and the patient’s condition.</p> <p><bold>CONCLUSION: </bold>Drug-induced liver injury remains a pressing clinical and diagnostic problem in modern medicine. Even drugs that are considered safe and widely used in clinical practice can cause liver damage under certain conditions. Individual drug interaction profiles and treatment duration can increase the risk of hepatotoxicity. Therefore, no drug can be considered completely harmless to the liver, highlighting the need for rational prescribing, liver function monitoring, and careful attention to possible adverse effects of medications.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>За последние два десятилетия число зафиксированных случаев лекарственного повреждения печени (ЛПП) возросло в 30 раз, что напрямую связано с расширением арсенала лекарственных средств, представленных на фармацевтическом рынке. Согласно статистике, в России ЛПП диагностируют у 3% пациентов, в то время как за рубежом этот показатель составляет 10–20 случаев на 100 тыс. человек. При этом во всём мире ежегодно отмечено около 40 000 летальных исходов вследствие ЛПП.</p> <p>В медицинском научном обществе описано огромное число наиболее частых «виновников» гепатотоксичности. Мы же хотим обратить внимание на клинический случай ЛПП у мужчины 67 лет на фоне приёма эторикоксиба. Циклооксигеназа-2-селективные нестероидные противовоспалительные препараты довольно редко поражают печень, что делает данный клинический случай нестандартным, а значит — труднопрогнозируемым. Однако последствия индуцированного нестероидным противовоспалительным препаратом повреждения печени зачастую серьёзны: фульминантная печёночная недостаточность и гепаторенальный синдром. В связи с этим остановить длительно бессимптомный, жизнеугрожающий токсический процесс способно лишь настороженное отношение врача к принимаемым пациентом лекарственным средствам, а также умение с помощью диагностических тестов как можно раньше распознавать лекарственно-индуцированные состояния.</p> <p><bold>Описание клинического случая. </bold>В данной статье рассматривается клинический случай ЛПП у мужчины 67 лет на фоне приёма эторикоксиба. На утро 2-го дня плановой госпитализации для коррекции артериального давления пациент начал предъявлять жалобы на слабость и боли в эпигастральной области. В ходе детального физикального осмотра была выявлена иктеричность склер. Терапевтическая тактика включала в себя проведение лабораторных методов обследования, дифференциальной диагностики и лечебных мероприятий. После установления диагноза ЛПП был отменён причинный препарат и проведена адекватная терапия, в результате чего достигнуто улучшение лабораторных показателей и состояния пациента.</p> <p><bold>Заключение. </bold>ЛПП остаётся актуальной клинико-диагностической проблемой современной медицины. Даже препараты, считающиеся безопасными и широко применяемыми в клинической практике, при определённых условиях могут вызывать повреждение печёночной ткани. Индивидуальные особенности лекарственных взаимодействий и длительность приёма способны повышать риск гепатотоксичности. В связи с этим ни один лекарственный препарат не может рассматриваться как абсолютно безвредный для печени, что подчёркивает необходимость рационального назначения терапии, мониторинга функции печени и внимательного отношения к возможным побочным эффектам лекарственных средств.</p></trans-abstract><kwd-group xml:lang="en"><kwd>drug-induced liver injury</kwd><kwd>adverse drug reaction</kwd><kwd>etoricoxib</kwd><kwd>pharmacotherapy safety</kwd><kwd>drug monitoring</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лекарственно-индуцированное поражение печени</kwd><kwd>нежелательная лекарственная реакция</kwd><kwd>эторикоксиб</kwd><kwd>безопасность фармакотерапии</kwd><kwd>лекарственный мониторинг</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Korenskaya EG, Paramonova OV.
