Background:

Ralfinamide mesylate (FCE-26742A mesylate) is an orally available Na+ channel blocker derived from α-aminoamide, with function of suppressing pain[1][2].

Ralfinamide (30 mg/kg, 60 mg/kg; p.o.; twice daily; 42 days) treated with Ralfinamide (80 mg/kg; p.o.; twice daily; 7 days) preoperatively suppresses neuropathic pain[1].
