Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prilocaine hydrochloride is an amino amide local anesthetic that reversibly blocks sodium channels in nerve cell membranes, inhibiting nerve impulse propagation.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
Adults: 4 mg/kg (max 200 mg) via infiltration or nerve block; may repeat after 2 hours with 50% of initial dose.
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 half-life: 1.5-2 hours (adults, normal hepatic function). Prolonged in neonates (up to 8-12 hours) due to immature hepatic metabolism and reduced clearance; may cause methemoglobinemia. Hepatic impairment increases half-life.
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: ~95% as metabolites (primarily o-toluidine and 4-hydroxy-2-methylaniline) and <5% unchanged. Biliary/fecal: minimal (<2%).
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
