Mechanism of action

Bupivacaine reversibly binds to and inactivates voltage-gated sodium channels on the inner surface of nerve cell membranes, thereby preventing depolarization and action potential generation. This blocks conduction of sensory, motor, and autonomic nerve impulses in the area where it is injected. The drug is long-acting due to its high lipophilicity and protein binding, allowing sustained local anesthesia.
