ALPHACAINE HYDROCHLORIDE vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Local anesthetic that reversibly blocks sodium ion channels in neuronal membranes, preventing the generation and propagation of action potentials.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
1–2% solution via local infiltration or nerve block, up to a maximum of 4.5 mg/kg (or 300 mg) without epinephrine; with epinephrine, maximum 7 mg/kg (or 500 mg).
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 2.5-3.5 hours in adults; prolonged to 4-6 hours in hepatic impairment or elderly.
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.
Primarily renal excretion of unchanged drug and metabolites (70-80%); minor biliary elimination (10-15%); fecal excretion <5%.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
