Description

Lidocaine acts mainly by inhibiting sodium influx through sodium specific ion channels in the neuronal cell membrane, in particular the so called voltage-gated sodium channels. When the influx of sodium is interrupted, an action potential cannot arise and signal conduction is inhibited. The receptor site is thought to be located at the cytoplasmic (inner) portion of the sodium channel. Lidocaine binds more readily to sodium channels in activated state, thus onset of neuronal blockade is faster in neurons that are rapidly firing. This is referred to as state dependent blockade.

Lidocaine is a topical anesthetic used for the following purposes- To help prevent pain associated with minor surgical procedures in the ear, nose and throat To help prevent pain and or discomfort during dental procedures (e.g., prior to an injection) During general anesthesia to prevent coughing To help prevent pain during the final stages of childbirth, before the cutting or stitching of the perineum (skin between the vagina and anus)
