Which is the only local anesthetic that is available with levonordefrin?

Explanation:
Levonordefrin acts as a vasoconstrictor to slow the absorption of a local anesthetic, prolonging its effect. In dental practice, the only local anesthetic formulation that is available with levonordefrin is 2% mepivacaine with levonordefrin (typically 1:20,000). Other commonly used anesthetics, such as lidocaine, prilocaine, and articaine, are paired with epinephrine rather than levonordefrin. That makes mepivacaine the unique pairing with levonordefrin among the standard options.
