Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that inhibits depolarization of cardiac myocytes and nerve axons by binding to voltage-gated sodium channels and stabilizing the neuronal membrane, thereby preventing the propagation of action potentials.
Lidocaine is a class IB antiarrhythmic agent that blocks voltage-gated sodium channels, inhibiting the inward sodium current, thereby stabilizing cardiac membranes, decreasing automaticity, and increasing the fibrillation threshold. It also acts as a local anesthetic by reversibly blocking nerve impulse propagation.
Intravenous infusion: 1-4 mg/min (20-50 mcg/kg/min) for cardiac arrhythmias. Bolus: 1-1.5 mg/kg IV, then infusion.
Lidocaine: Initial IV bolus 1-1.5 mg/kg, then IV infusion 1-4 mg/min. Adjust for arrhythmia suppression.

Terminal elimination half-life approximately 1.5-2 hours after bolus, prolonged to 2-4 hours in heart failure or hepatic impairment; continuous infusion may show context-sensitive half-life.
Terminal half-life 1.5–2 hours (adults); prolonged in heart failure (up to 4–6 hours) or hepatic impairment (up to 8 hours).
Renal excretion of unchanged drug and metabolites; <10% unchanged in urine, >90% as metabolites (primarily monoethylglycinexylidide and glycinexylidide). Biliary/fecal elimination minimal (<1%).
Renal: ~90% as metabolites (major metabolite 4-hydroxyxylidine) and ~10% unchanged. Biliary/fecal: <5%.
