Not to be confused with Rufinamide.

Ralfinamide (INN) (code names NW-1029, FCE-26742A, PNU-0154339E)[1] is a multimodal drug which is under investigation by Newron Pharmaceuticals for the treatment of neuropathic pain and other pain conditions such as post-operative dental pain.[2][3][4][5]

It has a relatively complex pharmacology, acting as a mixed voltage-gated sodium channel blocker (including Nav1.7),[2][3] N-type calcium channel blocker,[2][3] noncompetitive NMDA receptor antagonist,[6] and monoamine oxidase B inhibitor.[7][8]

It has thus far progressed as far as phase IIb/phase III clinical trials.[5][9] In 2010 it failed a phase II trial for lower back pain.[10] Encouraging Phase II results have been announced for neuropathic pain.[11]
