LICART vs LIDOCAINE HYDROCHLORIDE VISCOUS
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.
Lidocaine is a local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and propagation of action potentials. It also has antiarrhythmic properties (Class Ib) by accelerating repolarization and reducing automaticity in cardiac tissues.
Adults: 50 mg orally once daily.
Adult: 15 mL (300 mg) orally every 3 hours, not to exceed 8 doses in 24 hours. Viscous formulation swished and swallowed.

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: 1.5–2 hours (adults); prolonged in heart failure (2.5–4 hours) or hepatic disease (up to 5–7 hours). Context: short t1/2 limits toxic accumulation with topical use.
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
Renal: ~90% as metabolites (mainly 4-hydroxy-2,6-xylidine and glucuronides), <10% unchanged. Biliary/fecal: minor (<5%).
