Benzonatate or 2,5,8,11,14,17,20,23,26-nonaoxaoctacosan-28-yl para-butylaminobenzoate is a non-narcotic oral antitussive (cough suppressant) with effects that last from 6 to 8 hours. Being non-narcotic, benzonatate is not prone to abuse like some other cough medications such as codeine or dextromethorphan. Benzonatate was approved by the FDA in 1958.
Benzonatate is a butylamine, chemically related to other ester local anesthetics such as procaine and tetracaine. Benzonatate is unrelated to codeine, dextromethorphan, and other opioids that are frequently used to suppress coughs.
