Abstract

Aim: Tramadol (TRM), a widely used opioid analgesic for moderate to severe pain, is associated with liver and kidney toxicity at high doses or prolonged use. This study investigates the protective role of rosmarinic acid (RA), a natural phenolic compound known for its antioxidant, anti-inflammatory, and cell-protective properties, against TRM-induced hepatorenal toxicity.<br />Methods: Thirty-five male Wistar rats were divided into five groups: Control, TRM, RA, TRM + RA25, and TRM + RA50. Rats received TRM (50 mg/kg) and RA (25 or 50 mg/kg), with liver and kidney function tests, oxidative stress, inflammation, ER stress, apoptosis, and tissue damage indicators assessed through qRT-PCR, ELISA, Western blotting, H&E, and immunohistochemical analysis.<br />Results: TRM induced liver and kidney dysfunctions, evident from increased ALT, AST, ALP, urea, creatinine, nephrin, TIM-1 and 8-OHdG levels, along with activated oxidative stress, inflammation, ER stress, and apoptosis pathways. RA significantly reduced these effects, ameliorating histologic and immunohistochemical markers of tissue damage and inflammation.<br />Conclusion: RA demonstrates therapeutic potential by mitigating TRM-induced hepatorenal toxicity and preserving tissue integrity.<br />Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.<br /> (Copyright © 2025 Elsevier Ltd.
