NCIt definition : The hydrochloride salt form of tetracaine, a benzoate ester, with anesthetic properties.
Upon administration, tetracaine reversibly binds voltage-gated sodium ion channels
in neuronal cell membranes and inhibits sodium influx. This prevents the initiation
and conduction of nerve impulses, and stabilizes neuronal membranes. This results
in a loss of sensation, and thereby provides analgesia and anesthesia.;
