Benzonatate

Benzonatate (pronounced ben-ZOE-na-tate) is a non-narcotic oral medication, used to suppress coughs. It is chemically related to other ester-type local anesthetics and is usually prescribed by doctors to patients suffering from a cough and cold symptoms.

Etymology

The term "Benzonatate" is derived from its chemical structure, which is composed of an ester linkage between 4-butylaminobenzoic acid and 2,5,8,11,14,17,20,23,26-nonaoxaoctacosan-28-ol.

Usage

Benzonatate is used to relieve coughing caused by the common cold and other breathing problems (e.g., pneumonia, bronchitis, emphysema, asthma). It works by reducing the reflex in the lungs that causes the urge to cough.

Side Effects

Common side effects of Benzonatate include drowsiness, dizziness, headache, constipation, and nausea. Serious allergic reactions to this drug are rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.
