Which local anesthetic's brand name is Marcaine?

• A. Articaine
• B. Lidocaine
• C. Procaine
• D. Bupivacaine

Answer: (D)

Marcaine is the brand name for bupivacaine, a long-acting amide local anesthetic. In dental practice, recognizing brand names helps you map to the actual drug: Marcaine equals bupivacaine, which provides longer-lasting numbness than many other agents. Other common local anesthetics have different brands—articaine is often marketed as Septocaine, lidocaine as Xylocaine, and procaine as Novocain—so Marcaine uniquely identifies bupivacaine. Its longer duration makes it useful for longer procedures or nerve blocks, but it also carries a higher risk of systemic toxicity, so it must be dosed carefully.
