Diazepam abolished seizures but significantly deepened rat sedation (p <. 05) but significantly increased seizures (p <. Naloxone reversed tramadol-induced respiratory depression (p <. Sedation depth, temperature, number of seizures, and intensity, whole-body plethysmography parameters and electroencephalography activity were measured. Sprague-Dawley rats overdosed with 75 mg/kg intraperitoneal (IP) tramadol were randomized into four groups to receive solvent (control group), diazepam (1.77 mg/kg IP), naloxone (2 mg/kg intravenous bolus followed by 4 mg/kg/h infusion), and diazepam/naloxone combination. To investigate the most efficient antidote to reverse tramadol-induced seizures and respiratory depression in overdose. Tramadol overdose results not only in central nervous system (CNS) depression attributed to its opioid properties but also in seizures, possibly related to non-opioidergic pathways, thus questioning the efficiency of naloxone to reverse tramadol-induced CNS toxicity. Since the banning of dextropropoxyphene from the market, overdoses, and fatalities attributed to tramadol, a WHO step-2 opioid analgesic, have increased markedly.
