“Both nipecotic acid (a classical blocker of GABA uptake) and riluzole were found to inhibit [3H]GABA uptake in a dose-related fashion (IC50 = 3.6 x 10(-6) M and 4.3 x 10(-5) M for nipecotic acid and riluzole, respectively).”
“These results indicate that, in addition to its antiglutamate properties, riluzole probably also promotes synaptic GABA accumulation, which might contribute to the anticonvulsant and/or anesthetic properties of this pharmacological agent.”
