Introduction:
Tetracaine is an anesthetic. The action intensity of local anesthesia is 10 times that of procaine, which can last for 2 ~ 3H and has strong penetration. It is mainly used for surface anesthesia of eyes, nose, throat and urinary tract. After absorption, it can cause convulsion and then turn to respiratory depression. Generally, it is not used for anesthesia such as infiltration and conduction.

Pharmacological action:
Block the voltage dependent sodium channel, block the conduction and produce anesthetic effect. Local anesthetics have lipophilic effect. Non dissociative type is the necessary condition for penetrating into the nerve, and after penetrating into the nerve, they must be transformed into dissociated charged cations to play their role. The proportion of dissociated / non dissociated anesthetics varies with different local anesthetics.
