(R) - (+) -Bupivacaine hydrochloride

(R) - (+) -Bupivacaine hydrochloride is a voltage-gated sodium channel (sodium channel) inhibitor. It selectively blocks voltage-gated sodium ion channels on neuronal cell membranes, inhibiting the influx of sodium ions and thereby preventing the generation and transmission of nerve impulses, producing a local anesthetic effect.
