Lidocaine, also known as xylocaine and lignocaine, is a medication used to numb tissue in a specific area and to treat ventricular tachycardia. It can also be used for nerve blocks.
Lidocaine is an amide-type, local anesthetic medication available in a patch form. Lidocaine, like other local anesthetics causes a loss of sensation by reducing the flow of sodium in and out nerves to decrease the initiation and transfer of nerve signals. The FDA approved lidocaine patch in March 1999.
