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 an amide-type local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses.
Intravenous infusion: 1-4 mg/min (20-50 mcg/kg/min) for cardiac arrhythmias. Bolus: 1-1.5 mg/kg IV, then infusion.
Apply up to 3 patches topically once daily for up to 12 hours per day. Maximum 3 patches (210 mg lidocaine) per day.

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.
1.5-2 hours (terminal); prolonged in hepatic dysfunction or heart failure
Renal excretion of unchanged drug and metabolites; <10% unchanged in urine, >90% as metabolites (primarily monoethylglycinexylidide and glycinexylidide). Biliary/fecal elimination minimal (<1%).
Renal (80-90% as metabolites, <10% unchanged), biliary/fecal (minor, <5%)
