Benzonatate

Benzonatate is a non-narcotic oral cough suppressant, or antitussive, with effects that last from 6 to 8 hours. Its formal name is 2,5,8,11,14,17,20,23,26-nonaoxaoctacosan-28-yl para-butylaminobenzoate. 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.
