Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that reversibly blocks sodium ion channels in neuronal membranes, preventing the generation and propagation of action potentials.
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.
1–2% solution via local infiltration or nerve block, up to a maximum of 4.5 mg/kg (or 300 mg) without epinephrine; with epinephrine, maximum 7 mg/kg (or 500 mg).
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 half-life 2.5-3.5 hours in adults; prolonged to 4-6 hours in hepatic impairment or elderly.
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.
Primarily renal excretion of unchanged drug and metabolites (70-80%); minor biliary elimination (10-15%); fecal excretion <5%.
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%).
