Bupivacaine Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Bupivacaine is a brand name. Its generic name is Bupivacaine.

Introduction

Bupivacaine is an anesthetic and analgesic agent used to provide effective relief from pain during dental treatment, general surgery, obstetrics, urology, orthopedics and other medical procedures. It is known as a “local” anesthetic, meaning that it produces a localized numbing effect in the area where it is injected. It works by blocking pain signals sent between nerves and the brain.

Uses

Bupivacaine is primarily used to reduce or prevent pain when used locally by injection, infiltration and nerve block (doing regional anesthesia). It is also used to block motor nerves of skeletal muscles during various surgical procedures.

Mechanism of Action

Bupivacaine works by inhibiting the movement of sodium ions through the cell's voltage-sensitive sodium gates. Doing this prevents nerve cells from sending and receiving the pain signal to and from the brain.

How Long Does it Take to Work?

Bupivacaine generally takes up to 10 minutes to become effective once it is administered via injection. The effect is generally localized to the area of injection.

Absorption

Bupivacaine is absorbed both through blood vessels and through direct penetration into the tissue surrounding the area of injection.

Route of Elimination

Bupivacaine is excreted largely unchanged from the body via the kidneys within 24-48 hours.

Dosage

The dosage of bupivacaine should be individualized according to the particular area of injection, type of procedure, amount of local anesthetic necessary for the procedure, and the patient’s sensitivity to local anesthetics.

The dose for intercostal block is 0.25% bupivacaine (2.5 mg/ml) in a single-injection technique administered at a volume not exceeding 3 ml. For infiltration anesthesia, 1% bupivacaine (10 mg/ml) is used in a single-injection technique using a maximum volume restriction of 10 ml.
