What is lidocaine-injection (local), and how does it work (mechanism of action)?

Lidocaine injection is a local anesthetic. This means that it reduces sensation or pain in the area of the body where it is injected and does not affect other areas. It is similar to bupivacaine (Marcaine), articaine (Zorcaine), and Mepivacaine (Carbocaine). These drugs reduce sensation or pain by blocking nerve impulses that send pain sensations to the brain. Lidocaine starts working within 90 seconds and the effects last about 20 minutes. The FDA approved lidocaine in November 1948.
