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.
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).
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).
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.
右酮洛芬氨丁三醇是最常用的用于控制疼痛的抗炎镇痛药之一。本研究旨在探讨右酮洛芬对青霉素诱导的大鼠癫痫样活动的影响。
本研究使用了28只体重220 - 240克的雄性Wistar大鼠。在乌拉坦麻醉下植入三极电极。通过向大鼠左侧躯体运动皮层微量注射500单位(IU)青霉素诱导癫痫样活动。在注射青霉素30分钟后腹腔注射右酮洛芬(5、25和50毫克/千克)。通过皮层脑电图(ECoG)评估癫痫样活动。
低剂量右酮洛芬(5毫克/千克)注射后60分钟降低了癫痫样活动的平均棘波频率。然而,与对照组相比,25毫克/千克和50毫克/千克右酮洛芬在注射后30分钟显著降低了平均棘波频率(p < 0.05)。所有组癫痫样放电的幅度均未受影响(p > 0.05)。
本研究表明,在青霉素诱导的癫痫模型中,右酮洛芬以5毫克/千克、25毫克/千克和50毫克/千克(尤其是25毫克/千克和50毫克/千克)给药时具有显著的抗惊厥作用。所得数据表明右酮洛芬可能在对抗癫痫发作中发挥重要作用。
