Description: Bupivacaine is a BK/SK, Kv1, Kv3, TASK-2 K Channel and voltage-gated Na channel blocker used as an anesthetic. It maybe neurotoxic at high does, inducing apoptosis in neuroblastoma cells. It acts by binding to the intracellular portion of voltage-gated sodium channels and blocking sodium influx into nerve cells.
