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 through voltage-gated sodium channels, thereby blocking the initiation and propagation of action potentials, resulting in local anesthesia.
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.
Maximum 4.5 mg/kg (not to exceed 300 mg) via subcutaneous infiltration, epidural, or nerve block; repeat dosing after 30 minutes if needed.

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: ~1.5–2 hours (adults). Prolonged in hepatic impairment, congestive heart failure, or neonates.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal: ~90% as metabolites (mostly 4-hydroxy-2,6-xylidine and conjugates); <10% unchanged. Biliary/fecal: minor.
