Which local anesthetic is packaged in 2 different concentrations?

  1. Lidocaine

  2. Mepivacaine

  3. Bupivacaine

  4. Articaine

The correct answer is: Mepivacaine

Two different concentrations of Lidocaine are packaged because Lidocaine is widely used as both a local anesthetic and a treatment for cardiac arrhythmias. This allows for more specific and controlled dosing for each use. The other options, Mepivacaine, Bupivacaine, and Articaine, do not have multiple concentrations available due to their primary use as local anesthetics.
