10-Dehydrogingerdione Attenuates Tramadol-Induced Nephrotoxicity by Modulating Renal Oxidative Stress, Inflammation...

Area of Science:

• Pharmacology
• Toxicology
• Nephrology

Background:

• Tramadol is a widely used synthetic opioid analgesic for managing moderate to severe pain.
• Opioid analgesics, including tramadol, can pose risks of adverse effects, particularly on renal function during excretion.
• Monitoring tramadol dosage is crucial to mitigate potential harm, such as renal cellular damage.

Purpose of the Study:

• To investigate the adverse effects of tramadol administration on renal tissues.
• To evaluate the renoprotective potential of 10-dehydrogingerdione (10-DHGD) against tramadol-induced nephrotoxicity.

Main Methods:

• Assessment of serum biochemical markers including urea, creatinine, and uric acid.
• Evaluation of renal immune expression of key proteins such as NF-κB and caspase-3.
• Measurement of oxidative stress markers: malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and heme oxygenase-1 (HO-1).
• Histopathological examination of renal tissues to corroborate biochemical findings.

Main Results:

• Tramadol intake significantly elevated serum urea, creatinine, and uric acid levels.
• Tramadol increased renal expression of NF-κB and caspase-3, alongside elevated MDA, TLR4, and ERK1.
• Tramadol administration led to a decrease in protective antioxidants: GSH, SOD, and HO-1.
• 10-DHGD administration counteracted the detrimental effects of tramadol, reducing elevated markers and restoring antioxidant levels, supported by histopathology.

Conclusions:

• Tramadol administration exerts significant nephrotoxic effects, indicated by altered biochemical markers and oxidative stress.
• 10-dehydrogingerdione (10-DHGD) demonstrates a notable renoprotective potential against tramadol-induced renal damage.
• Further research into 10-DHGD as a therapeutic agent for mitigating opioid-induced nephrotoxicity is warranted.
