Local anesthetics: Lidocaine, bupivicaine, tetracaine, mepivicaine, ropivicaine, etc.

Drugs: That prevent the "firing" of the nerve. They do this by neutralizing the propagation of the impulse down the axon of the nerve. Locals such as Lidocaine (lignocaine in europe) or tetracaine or procaine but some people feel that simply injecting any safe liquid into the tissues can do this, such as saline--although i would stick with the better suited local anesthetics.

See below: The medications used for local anesthesia vary in type and specificity depending on the location being treated. These medications are loosely grouped in to either an ester or amide local anesthetics based on their chemical nature and make-up. Your anesthesiologist will be able to discuss these chemical in detail for you.
