Role: local anesthetics. Local anesthetic intensity: tetracaine>tetracaine  hcl>lidocaine>lidcaine hcl> benzocaine > procaine>procaine hcl,  but there are corresponding side effects. Mainly used for surface anesthesia of  the eyes, nose, throat and urinary tract. It can cause convulsions after  absorption, and then it is converted to respiratory depression, and is  generally  not used for anesthesia such as infiltration and conduction. Widely  used in  hospitals, dentists, tattoos, fitness and extended male ejaculation  delays

Note: Lidocaine hydrochloride is dissolved in water and is generally used as  a liquid. Lidocaine is not dissolved in water and is generally used as a  cream.

Lidocaine is a local anesthetic and antiarrhythmic drug. It is clinically  used for infiltration anesthesia, epidural anesthesia, surface anesthesia  (including in the thoracoscopy or abdominal surgery for mucosal anesthesia) and  nerve conduction block. The drug can also be used for acute myocardial  infarction after ventricular premature beats and ventricular tachycardia, and  for digitalis poisoning, cardiac surgery and ventricular arrhythmias caused by  cardiac catheterization. But it is usually ineffective for supraventricular  arrhythmias.
