Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker, stabilizing neuronal membranes by inhibiting the influx of sodium ions, thereby preventing the propagation of action potentials and producing local anesthesia.
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.
Lidocaine 2% topical gel: Apply 1-2 grams (approximately 5-10 cm ribbon) to affected area every 4-6 hours as needed, not to exceed 5 grams per day. For infiltration anesthesia: 1% solution, 0.5-5 mL injected locally; maximum 4.5 mg/kg.
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.

1.5–2 hours (terminal); prolonged in hepatic impairment
Terminal elimination half-life: 1.5–2 hours in adults with normal hepatic function; may be prolonged to 3–5 hours in patients with hepatic impairment or congestive heart failure.
Renal (10% unchanged; 80% as metabolites), biliary/fecal (10%)
Renal excretion of metabolites (predominantly 4-hydroxy-2,6-xylidine and conjugates) accounts for >80% of elimination; less than 10% eliminated unchanged in urine. Biliary/fecal excretion of metabolites contributes <10%.
