Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses. It also has antiarrhythmic properties by decreasing automaticity in Purkinje fibers and suppressing ventricular arrhythmias.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
Intrathecal administration for spinal anesthesia: 50-100 mg (1.5-2 mL of 5% solution) as a single dose. For continuous epidural or peripheral nerve block, 0.8% solution with dextrose 5% is not typically used; refer to 1-2% lidocaine without dextrose for continuous infusion.
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 (adults); prolonged in heart failure (up to 5-8 hours) or hepatic impairment (up to 10-15 hours). Clinically, context indicates redistribution half-life ~8 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.
Renal (metabolites: 4-hydroxyxylidine, glycylxylidide, monoethylglycinexylidide; <10% unchanged). Biliary/fecal negligible.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
