LICART vs MARCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Bupivacaine blocks sodium ion channels in nerve cell membranes, inhibiting the generation and propagation of action potentials, resulting in local anesthesia.
Adults: 50 mg orally once daily.
Local infiltration: 0.25-0.5% solution, up to 30 mL; peripheral nerve block: 0.25-0.5% solution, 30-40 mL; epidural: 0.5-0.75% solution, 15-30 mL. Maximum dose: 2 mg/kg (with epinephrine), 1.5 mg/kg (without epinephrine).

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.
Terminal elimination half-life: 2.5-4 hours in adults (longer in neonates and hepatic impairment; up to 8-12 hours). Clinically, accumulation occurs with continuous infusion or repeated doses.
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
Renal excretion of metabolites (approximately 90-95% as para-aminobenzoic acid and other metabolites); less than 5% unchanged in urine. Biliary/fecal excretion is minimal.
