“…Previous studies have revealed that metamizole is associated with a major risk of liver injury 7 . In addition, it has been proven in previous studies that diclofenac, another NSAID drug other than metamizole, has a toxic effect on the liver 8 . However, there is no sufficient evidence to determine whether metamizole increases liver risk or not 2 .…”

Background and Objective: Metamizole is a non-selective cyclooxygenase (COX) inhibitor NSAID with a strong analgesic and spasmolytic effects. It is the most common analgesic in the world. Thiamine pyrophosphate (TPP) protects the liver tissue against oxidative damage. The aim of our study was to analyze the effect of TPP against possible liver injury and dysfunction of metamizole in rats biochemically and histopathologically. Materials and Methods: The animals were grouped as healthy (HG), 500 mg kgG 1 metamizole (MT-500), 1000 mg kgG 1 metamizole (MT-1000), 25 mg kgG 1 TPP+500 mg kgG 1 metamizole (TMT-500), 25 mg kgG 1 TPP+1000 mg kgG 1 metamizole (TMT-1000) groups. The TMT-500 and TMT-1000 groups of animals were injected intraperitoneally (ip) at the dose of 25 mg kgG 1 of TPP. Distilled water as the solvent was injected ip to the HG, MT-500 and MT-100 groups. One hour after injecting TPP and distilled water, metamizole 500 and 1000 mg kgG 1 doses were administered orally to the TMT-500 and TMT-1000 groups. The TPP was administered once and metamizole twice a day for 14 days. The animals were euthanized with high-dose anesthesia. The liver tissues excised from the animals were analyzed biochemically and histopathologically. Results: In both doses metamizole significantly increased MDA, ALT and AST levels and decreased tGSH, SOD and CAT levels compared to the healthy group. TPP significantly prevented the decrease of tGSH, SOD and CAT levels and the increase of MDA, ALT and AST levels with metamizole. There was no statistical difference in all of the levels between the TMT-500 and TMT-1000 groups. The histopathological findings indicated TPP significantly suppressed the damage induced by metamizole. Conclusion: The metamizole was possible to cause moderate damage to liver tissue. Therefore, it was considered that the use of TTP to reduce liver toxicity could be clinically beneficial.
