چکیده
Background: There are paradoxical information about role of tramadol in seizures, we aimed this study to assay role of opioid receptor in tramadol seizureMaterials and Methods: Tramadol (50 mg/mL) was infused at the constant rate of 0.5 mL/minute to mice. Infusion was cut if forelimb clonus followed by full clonus of the body. Dose of Tramadol (mg/kg mouse weight) to induce colonic seizures was as index of seizure threshold. Animals were divided into 4 groups of 6. Control group, tramadol (T) ,(Meth+T) and (Nal+T) group , 24 hours following injections, the animals were scarified .The brain tissues was assayed for malondialdehyde (MDA) ,glutathione (GSH) , Reactive Oxygen(ROS).Results:The minimal dose of Tramadol to induce colonic seizures was 140 mg/kg P< 0.05 and Naloxone could have increased the threshold to 175 mg/kg , P< 0,05,combination of tramadol with methadone decreased the threshold significantly. Also combination of Naloxone with tramadol improved oxidative stress but methadone before tramadol has not increased oxidative stress significantlyDiscussion: The μ opioid receptor cane be involved in tramadol seizure and naloxone can be used for preventing seizure by tramadol in emergency conditions but much more precise clinical trials are necessary.کلیدواژه ها
