SEPTOCAINE vs XYLOCAINE DENTAL
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 is an amide-type local anesthetic that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking the initiation and conduction of nerve impulses.
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).
Xylocaine Dental (lidocaine HCl 2% with epinephrine 1:100,000 or 1:50,000): For infiltration/inferior alveolar nerve block, maximum dose 3.4 mg/kg (4.5 mg/kg with epinephrine 1:100,000) not to exceed 300 mg; usual adult dose: 1–5 mL (20–100 mg) administered via oral submucosal injection.

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.
1.5–2 hours in adults with normal hepatic function. Prolonged to 2–3 hours in patients with hepatic impairment or congestive heart failure; may exceed 5 hours in severe hepatic disease.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
Renal excretion of unchanged drug and metabolites accounts for >95% of the dose. Approximately 70% is excreted as the metabolite 4-hydroxy-2,6-xylidine; less than 10% is unchanged lidocaine. Biliary/fecal excretion is minimal (<5%).
