What is Benzonatate

Benzonatate is a non-narcotic oral antitussive (cough suppressant) drug which works by anesthetizing the tissues of the lungs and pleura responsible for the cough reflex. It is chemically related to other ester anesthetics such as procaine. It has an anesthetic (numbing) action similar to that of benzocaine and “numbs” the stretch sensors in the lungs. It is the stretching of these sensors with breathing that causes the cough. It was approved by the FDA in 1958.

Benzonatate mechanism of action

Benzonatate acts peripherally, anesthetizing the stretch receptors of vagal afferent fibers in the alveoli of the lungs, bronchi, and pleura. Since these receptors are responsible for mediating the cough reflex, anesthetizing these receptors result in the inhibiton of cough production. Benzonatate also suppresses transmission of the cough reflex at the level of the medulla where the afferent impulse is transmitted to the motor nerves. When applied locally, Benzonatate binds within the intracellular portion of voltage-gated sodium channels, decreasing the rate of membrane depolarization and increasing the threshold for electrical excitability.
