Mechanism of action

Lidocaine is a local anesthetic that penetrates the skin and underlying tissues to reversibly inhibit sodium influx in nerve cell membranes, thereby preventing depolarization and conduction of pain impulses. The transdermal patch formulation provides sustained, localized delivery to affected areas, minimizing systemic absorption and side effects compared to oral or injectable routes.
