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 the initiation and conduction of nerve impulses. Dextrose provides caloric support.
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.
For IV administration, typical adult dose is 5-7 mg/kg intravenously as a single bolus, followed by 0.5-1 mg/kg every 5-10 minutes as needed, up to a maximum total dose of 200-300 mg. For epidural or caudal anesthesia, 15-20 mL of the 5% solution provides adequate block. For peripheral nerve block, 10-30 mL. Do not exceed 5 mg/kg per dose intravenously or 300 mg per dose by infiltration.

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 is approximately 1.5 to 2 hours in healthy adults after intravenous administration. In patients with heart failure or hepatic impairment, half-life may be prolonged to 4-6 hours or more. After epidural administration, half-life may be slightly longer due to ongoing absorption.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal excretion of unchanged lidocaine and metabolites; less than 10% excreted unchanged in urine. Hepatic metabolism produces active metabolites (MEGX, GX) which are renally excreted. Biliary/fecal excretion negligible.
