Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic agent that inhibits sodium ion influx into nerve cells, blocking nerve conduction and pain sensation.
Lidocaine stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking impulse initiation and conduction. It binds to voltage-gated sodium channels in the inactivated state, preventing depolarization and propagation of action potentials.
Apply one 10 mg/10 cm² transdermal patch to intact skin once daily, typically in the morning; remove after 24 hours and replace with a new patch.
Adult dose: 1-30 mL of 1% or 2% solution (10-600 mg) via subcutaneous infiltration, peripheral nerve block, or epidural; max 4.5 mg/kg (300 mg without epinephrine, 7 mg/kg [500 mg] with epinephrine) per 2-hour period.

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
Terminal elimination half-life approximately 1.5-2 hours in adults; prolonged in hepatic impairment (up to 3-4 hours) and congestive heart failure.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal excretion of metabolites (90-95% as metabolites, <5% unchanged); biliary/fecal excretion minimal (<1%).
