描述 Lamotrigine belongs to the second generation of antiepileptic drugs (AEDs)[3]. Co-application of lamotrigine (1 ~ 300 µM) resulted in a concentration-dependent reduction in peak amplitude of currents induced by 3 µM of 5-HT for an IC50 value of 28.2 ± 3.6 µM with a Hill coefficient of 1.2 ± 0.1[4]. Moreover, intrathecally administered lamotrigine could prevent the activation of the glutamate receptors involved in pain transmission and central sensitization, such as AMPA, NMDA, and metabotropic receptors[5]. Studies showed lamotrigine could ameliorate executive dysfunction and brain inflammatory response in the mouse model of AD[6].
