Topiramate (TOP) is a novel anticonvulsant drug with multiple mechanisms of action used in the treatment of epilepsy. Measurements of cerebral GABA were obtained in six controls using 1H MRS at baseline and at 3 and 6 hours following the administration of 3 mg/kg of TOP. Brain GABA concentrations rose by 72% at 3 hours and by 64% at 6 hours compared with baseline (p < 0.004). This study demonstrates that TOP significantly increases human cerebral GABA concentrations in healthy individuals.
托吡酯(TOP)是一种新型抗惊厥药物,具有多种作用机制,用于治疗癫痫。在6名对照者中,于基线时以及给予3mg/kg托吡酯后3小时和6小时,使用1H磁共振波谱法测量脑内γ-氨基丁酸(GABA)。与基线相比,脑内GABA浓度在3小时时升高了72%,在6小时时升高了64%(p<0.004)。本研究表明,托吡酯可使健康个体的脑内GABA浓度显著升高。
