Exangit - General Information
Exangit 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
Pharmacology of Exangit
Exangit, a non-narcotic antitussive agent chemically related to tetracaine and other ester-type local anesthetics, is used to suppress cough associated with both acute and chronic respiratory conditions.
Exangit for patients
Release of benzonatate from the softgel in the mouth can produce a temporary local anesthesia of the oral mucosa and choking could occur. Therefore, the softgels should be swallowed without chewing.
No information provided.
Hypersensitivity to benzonatate or related compounds.
Additional information about Exangit
Exangit Indication: For the symptomatic relief of cough
Mechanism Of Action: Exangit acts peripherally, anesthetizing the stretch receptors of vagal afferent fibers in the alveoli of the lungs, bronchi, and pleura. When applied locally, Exangit binds within the intracellular portion of voltage-gated sodium channels, decreasing the rate of membrane depolarization and increasing the threshold for electrical excitability.
