BUPIVACAINE HYDROCHLORIDE PRESERVATIVE FREE vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupivacaine blocks voltage-gated sodium channels on neuronal membranes, inhibiting the propagation of action potentials and resulting in local anesthesia.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
0.25-0.5% solution, up to 2 mg/kg (max 150 mg) per dose via infiltration, peripheral nerve block, or epidural; may repeat every 3-6 hours as needed. For epidural: 0.5% solution, 15-20 mL for surgical anesthesia.
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 is 2.7 hours (range 1.5-5.5 hours). Prolonged up to 8-10 hours in neonates and 24-48 hours in severe hepatic impairment.
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 excretion accounts for approximately 95% of the dose, with about 50% excreted unchanged. The remainder is primarily hepatic metabolism followed by renal elimination of metabolites. Biliary/fecal excretion is minimal (<5%).
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
