Local anaesthetic agents suppress action potentials in excitable tissues by blocking voltage-gated Naþ channels. In doing so, they inhibit action potentials in nociceptive fibres and so block the transmission of pain impulses. This article describes nerve anatomy and physiology, the molecular site of action of local anaesthetics, and their pharmacology.
