Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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 is an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking the initiation and conduction of nerve impulses.
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.
Xylocaine Dental (lidocaine HCl 2% with epinephrine 1:100,000 or 1:50,000): For infiltration/inferior alveolar nerve block, maximum dose 3.4 mg/kg (4.5 mg/kg with epinephrine 1:100,000) not to exceed 300 mg; usual adult dose: 1–5 mL (20–100 mg) administered via oral submucosal injection.

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.
1.5–2 hours in adults with normal hepatic function. Prolonged to 2–3 hours in patients with hepatic impairment or congestive heart failure; may exceed 5 hours in severe hepatic disease.
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%.
Renal excretion of unchanged drug and metabolites accounts for >95% of the dose. Approximately 70% is excreted as the metabolite 4-hydroxy-2,6-xylidine; less than 10% is unchanged lidocaine. Biliary/fecal excretion is minimal (<5%).
