Bupivacaine HCl

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 317356

CAS#: 18010-40-7 (HCl)

Description: Bupivacaine, is a medication used to freeze tissue in a specific area. It is used by injecting it into the area, around a nerve that supplies the area, or into the spinal canal's epidural space. It is available mixed with a small amount of epinephrine to make it last longer. It typically begins working within 15 minutes and lasts for 2 to 8 hours. Bupivacaine binds to the intracellular portion of voltage-gated sodium channels and blocks sodium influx into nerve cells, which prevents depolarization. Without depolarization, no initiation or conduction of a pain signal can occur.
