Our study was designed to evaluate the effects of this agent on liver toxicity and to understand the protective roles of adenosine triphosphate (ATP), Liver-52 (Liv-52), and their combination. Male Wistar rats (250\u2013280 g) were randomly assigned to five groups (n = 6): healthy control (C), HCQ only (H), ATP plus HCQ (AH), Liv-52 plus HCQ (LH), and ATP\u2013Liv-52 plus HCQ (ALH). ATP (4 mg\/kg) was administered intraperitoneally once daily, whereas Liv-52 (20 mg\/kg) was administered orally via gavage. One hour later, all groups except C received HCQ (120 mg\/kg, orally, twice daily). All treatments were continued for seven consecutive days. At the end of the experiment, serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were measured, and liver tissues were analyzed for malondialdehyde (MDA), total glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) activities, along with histopathological evaluation. HCQ administration significantly increased oxidative stress, as evidenced by elevated MDA levels (p &lt; 0.01) and reduced antioxidant parameters, including GSH, SOD, and CAT (p &lt; 0.05), accompanied by prominent histopathological damage. Treatment with ATP or Liv-52 markedly ameliorated these alterations by decreasing MDA and restoring antioxidant markers. The combination treatment was observed to exhibit the most pronounced protective effect; it significantly reduced MDA levels, improved GSH, SOD, and CAT levels more effectively, and produced significant decreases in AST and ALT values (p &lt; 0.05).<\/jats:p>","DOI":"10.3390\/ijms27010421","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T16:08:00Z","timestamp":1767197280000},"page":"421","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Mitigating Hydroxychloroquine-Induced Oxidative Liver Damage: The Roles of Adenosine Triphosphate, Liv-52, and Their Combination in Rats"],"prefix":"10.3390","volume":"27","author":[{"given":"Meryem Yalvac","family":"Kandefer","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Mengucek Gazi Education and Research Hospital, Erzincan Binali Y\u0131ld\u0131r\u0131m University, Erzincan 24100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3491-9798","authenticated-orcid":false,"given":"Esra Tuba","family":"Sezgin","sequence":"additional","affiliation":[{"name":"Anesthesia Program, Vocational School of Health Services, Erzincan Binali Y\u0131ld\u0131r\u0131m University, Erzincan 24100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5795-3177","authenticated-orcid":false,"given":"Bahadir","family":"Suleyman","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Faculty of Medicine, Erzincan Binali Y\u0131ld\u0131r\u0131m University, Erzincan 24100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ferda Keskin","family":"Cimen","sequence":"additional","affiliation":[{"name":"Department of Medical Pathology, Faculty of Medicine, Erzincan Binali Y\u0131ld\u0131r\u0131m University, Erzincan 24100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2702-3160","authenticated-orcid":false,"given":"Fulya","family":"Memi\u015f","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Mengucek Gazi Education and Research Hospital, Erzincan Binali Y\u0131ld\u0131r\u0131m University, Erzincan 24100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3248-1502","authenticated-orcid":false,"given":"Mine","family":"Gulaboglu","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Pharmacy, Ataturk University, Erzurum 25240, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9239-4099","authenticated-orcid":false,"given":"Halis","family":"Suleyman","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Faculty of Medicine, Erzincan Binali Y\u0131ld\u0131r\u0131m University, Erzincan 24100, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1080\/07853890.2020.1839959","article-title":"Hydroxychloroquine: A comprehensive review and its controversial role in coronavirus disease 2019","volume":"53","author":"Bansal","year":"2020","journal-title":"Ann.
