Bupivacaine, marketed under the brand name Marcaine among others, is a medication used to decrease feeling 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 is indicated for local anaesthesia including infiltration. Bupivacaine often is administered by epidural injection before total hip arthroplasty, Bupivacaine is also commonly injected to surgical.
Bupivacaine is related chemically and pharmacologically to the aminoacyl local anesthetics. It is a homologue of mepivacaine and is chemically related to lidocaine. All three of these anesthetics contain an amide linkage between the aromatic nucleus and the amino. They differ in this respect from the procaine-type local anesthetics, which have an ester linkage.
Bupivacaine hydrochloride injection, USP – Sterile isotonic solution containing sodium chloride. The pH of the solution is adjusted to between 4 and 6.5 with sodium hydroxide or hydrochloric acid.

How Does Bupivacaine Work?
The drug works by blocking the impulses of the nerves that transmit the sensation of pain. This includes impeding both the creation of nerve impulses and their ability to travel throughout the body. It does this specifically by binding to channels that carry sodium to the nerves, thus stopping their progress. Bupivacaine provides additional numbing by also blocking some potassium channels.
If it is administered incorrectly, bupivacaine can be cardiotoxic, which can result in damage to the muscles in and around the heart. The drug is not only ineffective when administered intravenously, but it has been known to be fatal. This is primarily because the drug does not work correctly when it is absorbed by the whole system instead of being administered locally. These risks are extremely low if the drug is injected as intended.
