Benzonatate, formerly known as Tessalon and KM-65, is a sodium channel protein antagonist. Benzonatate's mechanism of action is thought to be anesthesia of vagal sensory nerve fibers that mediate cough. Vagal sensory neurons highly express the Nav1.7 subtype of voltage-gated sodium channels, and inhibition of this channel inhibits the cough reflex.
