MEPIVACAÍNE

Mepivacaine is a local anesthetic that blocks sodium channels in nerve cell membranes, preventing the initiation and conduction of nerve impulses.

Mepivacaine is a local anesthetic that blocks sodium channels in nerve cell membranes, preventing the initiation and propagation of nerve impulses. Used for Local and regional anesthesia for dental procedures, Local and regional anesthesia for minor surgical procedures, Infiltration anesthesia.

At a glance

Mechanism of action

Mepivacaine reversibly inhibits sodium influx into nerve fibers by binding to sodium channels from the intracellular side, thereby stabilizing the neuronal membrane and raising the threshold for electrical excitability. This action prevents depolarization and propagation of action potentials, resulting in local anesthesia. The drug is an amide-type local anesthetic with intermediate duration of action.

Approved indications

• Local and regional anesthesia for dental procedures
• Local and regional anesthesia for minor surgical procedures
• Infiltration anesthesia

Common side effects

• Paresthesia
• Headache
• Dizziness
• Nervousness
• Allergic reactions (rare with amides)

Key clinical trials
