Acute treatment with dexketoprofen reduces penicillin induced epileptiform activity in wistar albino rats (dexketoprofen in penicillin induced seizure model).

AIM: Dexketoprofen trometamol is one of the most commonly used anti-inflammatory analgesic agents for pain control. This study aims to investigate the effect of dexketoprofen on penicillin-induced epileptiform activity in rats.

METHOD: In this study, 28 male Wistar rats weighing 220-240 g were used. Tripolar electrodes were implanted under urethane anesthesia. Epileptiform activity was induced by micro-injection of 500 units (IU) penicillin into the rats' left somatomotor cortex. Dexketoprofen (5, 25, and 50 mg/kg) was administrated intraperitoneally after 30 min of penicillin injection. Epileptiform activity was evaluated by electrocorticography (ECoG).

RESULTS

The low dose of dexketoprofen administration (5 mg/kg) reduced the mean spike frequency of epileptiform activity 60 min after its injection. However, 25 and 50 mg/kg dexketoprofen significantly reduced the mean spike frequency 30 min after the dexketoprofen injection compared to the control group (p < 0.05). The amplitudes of epileptiform discharges in all groups were unaffected (p > 0.05).

CONCLUSION

This study revealed that dexketoprofen had a significant anti-seizure effect when applied at 5 mg/kg, 25 mg/kg, and 50 mg/kg (especially at 25 and 50 mg/kg), in the penicillin-induced seizure model. The obtained data revealed that dexketoprofen might play an essential role against epileptic seizures.
