Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking the initiation and conduction of nerve impulses. Dextrose provides caloric support.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
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.
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 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.
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 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.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
