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 local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses. It also exhibits cardiac effects as a class IB antiarrhythmic agent by modulating sodium channels in myocardial cells.
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.
1-4 mg/kg via intravenous bolus, not to exceed 300 mg; may be followed by continuous infusion of 1-4 mg/min.

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) in healthy adults; prolonged in hepatic impairment (up to 5–7 hours), heart failure (up to 10 hours), or with continuous infusion (>24 h) due to accumulation. Context: requires monitoring in hepatic or cardiac dysfunction to avoid toxicity.
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 (primarily monoethylglycinexylidide [MEGX] and glycinexylidide [GX]), <10% unchanged. Fecal: <1%.
