Marcaine (Bupivacaine Hydrochloride) 0.75% Injection is a local anesthetic used to provide long-lasting pain relief during surgical, dental, and obstetric procedures. It works by blocking nerve signals in specific areas of the body, preventing the sensation of pain. Marcaine is particularly effective for regional anesthesia techniques such as epidurals, nerve blocks, and spinal anesthesia, making it ideal for managing pain in complex procedures, labor and delivery, and postoperative recovery.

Mechanism of Action
Bupivacaine works by binding to and inhibiting voltage-gated sodium channels on nerve cells. This action blocks nerve impulse generation and propagation, thereby providing a local anesthetic effect. Bupivacaine has a longer duration of action compared to other local anesthetics, making it particularly useful for prolonged surgical procedures or pain relief.
