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

IC50 & Target


In Vivo

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: 81 adult male Sprague–Dawley male rats (260–460 g)[1]
Dosage: 80 mg/kg (7 days preoperatively), 30 mg/kg, 60 mg/kg (postoperative)
Administration: Oral gavage; twice daily; until postoperative day 42
Result: Suppressed neuropathic pain.
