Molecular formula: C20H29N3O2

Local anesthetics block both the initiation and conduction of nerve impulses by decreasing the neuronal membrane's permeability to sodium ions through sodium channel inhibition. This reversibly stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and subsequent conduction blockade. ... PREVENT THE GENERATION & THE CONDUCTION OF THE NERVE IMPULSE. THEIR PRIMARY SITE OF ACTION IS THE CELL MEMBRANE. ... BLOCK CONDUCTION BY DECREASING OR PREVENTING THE TRANSIENT INCREASE IN THE PERMEABILITY OF EXCITABLE MEMBRANES TO NA IONS THAT IS NORMALLY PRODUCED BY A SLIGHT DEPOLARIZATION ... /LOCAL ANESTHETICS/ AS ANESTHETIC ACTION PROGRESSIVELY DEVELOPS IN A NERVE, THE THRESHOLD FOR ELECTRICAL EXCITABILITY GRADUALLY INCREASES, THE RATE OF RISE OF THE ACTION POTENTIAL DECLINES, IMPULSE CONDUCTION SLOWS, & THE SAFETY FACTOR FOR CONDUCTION DECREASES; THESE FACTORS DECREASE PROBABILITY OF PROPAGATION OF THE ACTION POTENTIAL, AND NERVE CONDUCTION FAILS. /LOCAL ANESTHETICS/ ... CAN BLOCK K ION CHANNELS. ... BLOCKADE OF CONDUCTION IS NOT ACCOMPANIED BY ANY LARGE OR CONSISTENT CHANGE IN RESTING MEMBRANE DUE TO BLOCK OF K ION CHANNELS. /LOCAL ANESTHETICS/ ... SITE AT WHICH LOCAL ANESTHETICS ACT, AT LEAST IN THEIR CHARGED FORM, IS ACCESSIBLE ONLY FROM THE INNER SURFACE OF THE MEMBRANE. ... LOCAL ANESTHETICS APPLIED EXTERNALLY FIRST MUST CROSS THE MEMBRANE BEFORE THEY CAN EXERT A BLOCKING ACTION. /LOCAL ANESTHETICS/ ... ACT ON ANY PART OF NERVOUS SYSTEM & ON EVERY TYPE OF NERVE FIBER. /LOCAL ANESTHETICS/
