DURANEST vs SEPTOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Etonidate is an ultrashort-acting nonbarbiturate hypnotic agent that produces anesthesia by enhancing GABA-mediated chloride conductance at GABA-A receptors, leading to central nervous system depression.
Articaine is a local anesthetic of the amide type that stabilizes the neuronal membrane by inhibiting sodium ion influx, thereby blocking nerve impulse conduction.
2-10 mL of a 1-2% solution, subarachnoid injection, single dose only.
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 4.5 hours (range 3-6 hours). Clinical context: Prolonged in severe hepatic impairment but not significantly in renal 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; renal excretion of metabolites accounts for <10% unchanged drug. Biliary/fecal elimination is minimal.
Primarily hepatic metabolism; less than 10% excreted unchanged in urine. Biliary/fecal elimination is negligible.
