How does lidocaine work on sodium channels
WebBoth lidocaine and carbamazepine have been shown to effect a use-dependent block of sodium channels in DRG neurones 18 days post-axotomy (74), and carbamazepine was recently shown to relieve paresthesias following damage to the ilioinguinal nerve during herniorraphy (75). WebFeb 8, 2024 · Answer: Lidocaine is a voltage-gated sodium channel inhibitor. When a painful stimulus is applied to the peripheral nervous system, nociceptors will be activated and send action potentials towards the central nervous system. These action potentials depend on the flux of sodium ions into the cell via voltage-gated sodium channels.
