Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
Lidocaine stabilizes the neuronal membrane by inhibiting sodium ion influx through voltage-gated sodium channels, thereby blocking the initiation and propagation of action potentials, resulting in local anesthesia.
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).
Maximum 4.5 mg/kg (not to exceed 300 mg) via subcutaneous infiltration, epidural, or nerve block; repeat dosing after 30 minutes if needed.

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.
Terminal elimination half-life: ~1.5–2 hours (adults). Prolonged in hepatic impairment, congestive heart failure, or neonates.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
Renal: ~90% as metabolites (mostly 4-hydroxy-2,6-xylidine and conjugates); <10% unchanged. Biliary/fecal: minor.
