Funapide (INN) (former developmental code names TV-45070 and XEN402) is a novel analgesic under development by Xenon Pharmaceuticals (formerly in partnership with Teva Pharmaceutical Industries) for the treatment of a variety of chronic pain conditions, including osteoarthritis, neuropathic pain, postherpetic neuralgia, and erythromelalgia, as well as dental pain.^[1]^[2]^[3]^[4] It acts as a small-molecule Na_v1.7 and Na_v1.8 voltage-gated sodium channel blocker.^[1]^[2]^[4] Funapide is being evaluated in humans in both oral and topical formulations, and as of July 2014, has reached phase IIb clinical trials.^[1]^[3]
