Also Known As: Tessalon, Benzonatate, Tessalon Perles
Benzonatate or 2,5,8,11,14,17,20,23,26-nonaoxaoctacosan-28-yl para-butylaminobenzoate is a non-opioid oral antitussive (cough suppressant) with effects that last from 6 to 8 hours. Since it is not an opioid, benzonatate is not prone to abuse like some other cough medications such as codeine. Benzonatate was approved by the U.S. Food and Drug Administration (FDA) in 1958.
An antitussive, benzonatate is employed to reduce coughing in various respiratory conditions such as, bronchitis, emphysema, influenza, and pneumonia. It should never be used to suppress a productive cough or in place of treatment of the actual cause of cough, such as asthma treatment.
