摘要

最近的实验证明,nmda拮抗剂MK-801在单胺耗竭的啮齿动物中具有运动刺激作用。这些发现是基于一个假设的通路回路,包括基底节区作为一个反映低运动障碍和高运动障碍的模型。我们用抗癫痫药物“拉莫三嗪”治疗了5例帕金森病患者,该药物似乎不是nmda拮抗剂,而是通过抑制突触前谷氨酸释放而发挥谷氨酸拮抗剂的功能。

Lamotrigine--antiparkinsonian activity by blockade of glutamate release?

Recent experiments provide evidence that the NMDA-antagonist MK-801 has a locomotor-stimulating effect in monoamine-depleted rodents. These findings are based upon a hypothetical pathway-circuit including the basal ganglia as a model reflecting hypo- and hyperkinetic movement disorders. We have treated 5 patients suffering from Parkinson's disease with the antiepileptic drug "lamotrigine" which does not appear to be an NMDA-antagonist but acts functionally as a glutamate antagonist by inhibition of presynaptic glutamate release.
