Description
A sodium channel inhibitor; preferentially inhibits inactivated Nav1.7 and Nav1.3 channels (IC50s = 406 and 900 µM, respectively) over resting (closed) Nav1.7 and Nav1.3 channels in whole-cell patch-clamp assays using HEK293 cells (IC50s = 1,584 and 2,464 µM, respectively); inhibits sodium currents in a rat sciatic nerve patch-clamp assay ex vivo at 100 µM; reduces dopamine levels in the striatum and hippocampus, as well as L-DOPA levels in the striatum, in rats at 100 mg/kg; reduces amphetamine-induced hyperactivity in mice at 0.5% w/w in the diet; reduces immobility time in the forced swim test in mice at 0.75% w/w in the diet
