Levobupivacaine reversibly binds voltage-gated sodium channels to modulate ionic flux and prevent the initiation and transmission of nerve impulses (stabilizing neuronal membrane), thereby resulting in analgesia and anesthesia. In comparison with racemic bupivacaine, levobupivacaine is associated with less vasodilation and has a longer duration of action."}]
