Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a local anesthetic that stabilizes neuronal membranes by inhibiting sodium ion influx, thereby blocking initiation and conduction of nerve impulses.
Lidocaine is an amide-type local anesthetic that blocks voltage-gated sodium channels (Nav1.7) in nerve cell membranes, inhibiting depolarization and conduction of nerve impulses, thereby producing both local anesthesia and systemic analgesia.
1-1.5 mg/kg IV bolus over 2-3 minutes, followed by continuous IV infusion of 1-4 mg/min for ventricular arrhythmias; maximum 3 mg/kg (or 200-300 mg) over 1 hour.
Apply 1 to 3 patches (5% lidocaine) to intact skin over most painful area for up to 12 hours within a 24-hour period; maximum 3 patches at once.

Terminal elimination half-life: 1.5-2 hours (adults); prolonged in heart failure (up to 4-6 hours) or hepatic impairment (up to 5-7 hours).
Terminal elimination half-life is 3–5 hours after topical application; after intravenous administration, half-life is 1.5–2 hours. Clinical context: Systemic accumulation possible with prolonged use on inflamed skin.
Renal: ~90% as metabolites and <10% unchanged. Biliary/fecal: minor (<1%).
Renal excretion of metabolites (primarily 4-hydroxy-2,6-xylidine glucuronide) accounts for >85% of elimination; <3% excreted unchanged; biliary/fecal elimination minimal (<10%).
