(R) - (+) -Bupivacaine (hydrochloride)

(R) - (+) -Bupivacaine hydrochloride is a voltage-gated sodium channel inhibitor. (R) - (+) -Bupivacaine hydrochloride can selectively block the voltage-gated sodium channels on nerve cell membranes, inhibit the influx of sodium ions, and thus prevent the generation and conduction of nerve impulses, exerting local anesthetic activity. (R) - (+) -Bupivacaine hydrochloride can be used in research of acute pains[1].
