Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Blocks voltage-gated sodium channels, inhibiting nerve impulse conduction by stabilizing the neuronal membrane and preventing depolarization.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
Local infiltration: 0.5% solution, up to 200 mg (40 mL) per dose. Nerve block: 0.5% solution, 100-200 mg (20-40 mL) per dose. Intravenous regional anesthesia (Bier block): 0.5% solution, 50-100 mg (10-20 mL) per dose. Maximum total dose: 200 mg without epinephrine, 250 mg with epinephrine 1:200,000.
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 7.7 minutes in adults with normal hepatic function. This short half-life reflects rapid hydrolysis by plasma pseudocholinesterases. In patients with pseudocholinesterase deficiency, half-life may be prolonged to 20-30 minutes.
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.
Primarily renal excretion of metabolites (para-aminobenzoic acid and diethylaminoethanol) and unchanged drug. Approximately 80% of a dose is excreted in urine as para-aminobenzoic acid and conjugates; <2% excreted unchanged. Biliary/fecal elimination is negligible.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
