Used in research for the treatment of chronic pain and inflammatory conditions. Acts as a selective inhibitor of the Nav1.7 voltage-gated sodium channel, which plays a key role in pain signal transmission. By blocking this channel, it helps reduce neuronal excitability and pain perception without affecting motor function or causing significant CNS side effects. Investigated for potential use in inherited erythromelalgia and other neuropathic pain disorders. Currently in preclinical and early clinical development stages.
