ALPHACAINE vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ALPHACAINE is a local anesthetic that binds to the intracellular portion of voltage-gated sodium channels, blocking sodium influx and preventing depolarization and conduction of nerve impulses.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
10-20 mg IM or IV every 4-6 hours as needed; maximum 80 mg/day.
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: 3.5-5.0 hours (prolonged in hepatic impairment; requires dose adjustment in Child-Pugh B or C).
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: ~60-70% unchanged; Hepatic metabolism: ~20-30% via CYP3A4 and CYP2C9; Fecal: <10%.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
