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 amide-type local anesthetic that blocks voltage-gated sodium channels in neuronal membranes, inhibiting the initiation and conduction of nerve impulses. Dextrose provides calories and does not have pharmacological activity.
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.
Intravenous administration: 1-1.5 mg/kg bolus, followed by 1-4 mg/min continuous infusion for ventricular arrhythmias. Maximum total dose: 3 mg/kg bolus; infusion for up to 24 hours. Note: 0.4% concentration = 4 mg/mL, 5% dextrose as diluent.

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 after a single dose in healthy adults. In patients with hepatic impairment, heart failure, or prolonged infusion, half-life can increase to >3 hours due to reduced clearance. Neonates: 3–6.3 hours.
Approximately 60% of the dose is excreted renally as unchanged drug and metabolites; the remainder is eliminated via biliary/fecal routes.
Renal: Approximately 90% of lidocaine is metabolized in the liver, and less than 10% is excreted unchanged in urine. The major metabolites (monoethylglycinexylidide and glycinexylidide) are excreted renally. Biliary/fecal excretion is minimal (<1%).
