Abstract

Background and Objective: Dexketoprofen trometamol is the dextrorotatory enantiomer of NSAID ketoprofen formulated as a tromethamine salt. This study aimed to perform immunohistochemical and electron microscopic evaluations of the effects of two different doses of dexketoprofen trometamol on kidneys via parenteral administration for 7 days. Materials and Methods: The study was conducted on 30 healthy, male Wistar albino rats, each weighing approximately 220 g. The rats were randomized and distributed across 3 groups, with 10 rats in each group. In the control group, 0.9% NaCl was used in 1 mL volume. In the other groups, and 16 mg kg–1/day doses of dexketoprofen trometamol (Arveles 50 mg/2 mL) in 1 mL were used intraperitoneally twice per day for 7 days. Results: In the high-dose group, a statistically significant reduction in live weight was observed, along with apoptosis and increased cell proliferation when compared to the control group. In the low-dose group, statistically significant increased apoptosis and cell proliferation were found. Conclusion: It was found that dexketoprofen trometamol induced apoptosis and caused cell proliferation and the 16 mg kg–1/day dose initiated the necrotic process. When an overdose of dexketoprofen trometamol (16 mg kg–1) was administered, losses in live weight and diffuse degeneration of the kidney tissue occurred. Administrations of this dosage are not recommended as similar effects on human tissue are predicted.
