MARCAINE HYDROCHLORIDE vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupivacaine is an amide-type local anesthetic that blocks voltage-gated sodium channels in nerve cell membranes, reversibly inhibiting nerve impulse propagation, particularly in sensory fibers.
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: 0.5% solution infiltrated up to 175 mg (35 mL) for minor procedures; for major procedures, up to 225 mg (45 mL) with epinephrine. Repeat doses at 3-hour intervals. Maximum dose 400 mg with epinephrine.
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 approximately 2.5 to 3.5 hours in adults; may be prolonged in neonates (8-12 hours) or patients with 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.
Primarily hepatic metabolism; less than 5% excreted unchanged in urine. Metabolites are excreted renally, with a small amount in feces via biliary elimination.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
