DURANEST vs LICART
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.
Licart is a fibrin sealant containing human fibrinogen and thrombin. When applied, thrombin converts fibrinogen to fibrin, forming a stable clot that mimics the final stage of coagulation. It also contains factor XIII and aprotinin to cross-link fibrin and inhibit fibrinolysis, respectively.
2-10 mL of a 1-2% solution, subarachnoid injection, single dose only.
Adults: 50 mg orally once daily.

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 of 6-8 hours in adults with normal renal function. Prolonged in renal impairment (up to 20-24 hours in ESRD), requiring dose adjustment in CrCl <30 mL/min.
Primarily hepatic metabolism; renal excretion of metabolites accounts for <10% unchanged drug. Biliary/fecal elimination is minimal.
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
