LICART vs PRILOCAINE HYDROCHLORIDE
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.
Prilocaine hydrochloride is an amino amide local anesthetic that reversibly blocks sodium channels in nerve cell membranes, inhibiting nerve impulse propagation.
Adults: 50 mg orally once daily.
Adults: 4 mg/kg (max 200 mg) via infiltration or nerve block; may repeat after 2 hours with 50% of initial dose.

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 half-life: 1.5-2 hours (adults, normal hepatic function). Prolonged in neonates (up to 8-12 hours) due to immature hepatic metabolism and reduced clearance; may cause methemoglobinemia. Hepatic impairment increases half-life.
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
Renal: ~95% as metabolites (primarily o-toluidine and 4-hydroxy-2-methylaniline) and <5% unchanged. Biliary/fecal: minimal (<2%).
