Pharmaceutical Raw Materials 99% Bupivacaine Base CAS 2180-92-9 USP/BP Standard local anesthetic

Bupivacaine is a highly effective sodium channel blocker and local anesthetic, esteemed for its remarkable efficacy. It precisely binds to the intracellular segments of sodium channels, halting the influx of sodium into nerve cells and obstructing depolarization. Its unique ability to swiftly penetrate pain-transmitting nerve fibers, which are slender and less myelinated, makes it exceptionally potent. This contrasts with its slower diffusion in thicker, heavily myelinated nerve fibers responsible for touch and proprioception.
