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 is a sodium channel blocker, stabilizing neuronal membranes by inhibiting the influx of sodium ions, thereby preventing the propagation of action potentials and producing 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.
Lidocaine 2% topical gel: Apply 1-2 grams (approximately 5-10 cm ribbon) to affected area every 4-6 hours as needed, not to exceed 5 grams per day. For infiltration anesthesia: 1% solution, 0.5-5 mL injected locally; maximum 4.5 mg/kg.

Terminal elimination half-life is approximately 7–9 hours; clinically, steady-state is achieved after 2–3 days of daily application.
1.5–2 hours (terminal); prolonged in hepatic impairment
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal (10% unchanged; 80% as metabolites), biliary/fecal (10%)
