Clinical Matrix

Mechanism of Action

Local anesthetic that reversibly blocks sodium channels in neuronal membranes, inhibiting nerve impulse conduction.

Lidocaine is an amide-type local anesthetic that blocks sodium channels, thereby inhibiting the propagation of action potentials in peripheral nerves, leading to local anesthesia.

Clinical Dosing

10-20 mg orally every 4-6 hours as needed; maximum 80 mg/day.

Spinal anesthesia: 1.5-2 mL (22.5-30 mg lidocaine) for lower extremity or perineal procedures; 2-3 mL (30-45 mg) for lower abdominal or urological procedures. Administered via lumbar puncture.

Direct Interaction

None Documented

Half-Life

2.5 hours; prolonged to 8 hours in cirrhosis due to reduced hepatic metabolism
