Which local anesthetic is the longest acting?

Lidocaine
Articaine
Bupivacaine
Mepivacaine

The correct answer is: Bupivacaine

Bupivacaine is the longest-acting local anesthetic among the options provided. Bupivacaine has a slower onset but provides more profound and prolonged anesthesia compared to other local anesthetics. It is commonly used for procedures requiring longer-lasting pain control, such as postoperative pain management or for procedures where extended pain relief is necessary. Lidocaine, Articaine, and Mepivacaine have shorter durations of action compared to Bupivacaine, making them less suitable for procedures that require long-lasting anesthesia.
