Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
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.
SEPTOCAINE (articaine HCl 4% with epinephrine 1:100,000 or 1:200,000) dental infiltration or nerve block: 0.5–1.7 mL (20–68 mg articaine) per injection site; maximum adult dose: 7 mg/kg (up to 500 mg total).

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.
Terminal elimination half-life in adults is 2-4 hours. In neonates, it may be prolonged to 8-12 hours due to immature hepatic function.
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%).
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
