Benzonatate 是外周口服镇咳药，对咳嗽延伸受体 (cough stretch receptors) 的活性具有抑制作用。它是丁卡因样代谢物，能够阻断呼吸延伸受体的钠通道并产生局部麻醉作用。

Benzonatate is an antagonist of sodium channel protein.

Na(+) currents are inhibited most potently by a benzonatate fraction containing the 9-ethoxy component.?Detectable effects of benzonatate occur at concentrations as low as 0.3 μM, which has been reported in humans. benzonatate has local anesthetic-like effects on voltage-gated sodium channels, including Nav1.7, which is a possible mechanism for cough suppression by the drug.
