Lidocaine is used for local anesthesia (numb tissues in a specific area)
How it Works
Lidocaine works by stopping sodium from entering the nerve endings at the site of pain, Pain is caused by the stimulation of pain receptors at the ends of nerves, this causes sodium to enter nerve endings which then causes an electrical signal to build up in the nerve. This electrical signal then passes along the nerve to the brain and interpreted as pain. When lignocaine stops sodium from entering the nerve endings it temporarily blocks the pathway of pain signals along nerves to the brain thus temporarily numbing the local tissue in that area.
