Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that stabilizes the neuronal membrane by inhibiting the ionic fluxes required for initiation and conduction of impulses, resulting in local anesthetic and antiarrhythmic effects.
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 infusion: 1-4 mg/min (0.2% solution = 2 mg/mL) for antiarrhythmic therapy; loading dose 1-1.5 mg/kg IV bolus, then infusion. Maximum infusion rate 4 mg/min.
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 is approximately 1.5–2 hours (mean 1.8 h) in adults with normal hepatic function; may be prolonged in patients with hepatic impairment (e.g., cirrhosis) or heart failure (up to 10 h), and in neonates (3–6 h).
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 excretion of unchanged drug and metabolites accounts for >95% of elimination, with ~10% as unchanged lidocaine and ~90% as metabolites (primarily 4-hydroxy-2,6-xylidine, with minor contribution from monoethylglycinexylidide and glycinexylidide). Biliary/fecal excretion is minimal (<1%).
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
