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 stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses.

Clinical Dosing

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

Adult: 5-25 mL (250-1250 mg lidocaine) of 5% lidocaine with glucose 7.5% solution, administered by caudal or lumbar epidural injection, single dose. Max total dose: 1250 mg.

Direct Interaction

None Documented

Half-Life

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