At a glance

Mechanism of action

This formulation combines local anesthetic agents (likely lidocaine and epinephrine based on the 'L+E' designation) to block nerve conduction in the mandibular division of the trigeminal nerve, producing sensory anesthesia of the lower jaw, teeth, and associated tissues. The epinephrine component acts as a vasoconstrictor to prolong anesthetic duration and reduce systemic absorption of the local anesthetic agent.

Approved indications

• Mandibular nerve block for dental anesthesia
• Regional anesthesia for oral and maxillofacial surgery

Common side effects

• Transient paresthesia
• Hematoma at injection site
• Temporary numbness beyond intended duration
• Allergic reaction (rare with amide anesthetics)
