LICART vs LIDOCAINE HYDROCHLORIDE PRESERVATIVE FREE
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 the neuronal membrane by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses. It also exhibits cardiac effects as a class IB antiarrhythmic agent by modulating sodium channels in myocardial cells.
Adults: 50 mg orally once daily.
1-4 mg/kg via intravenous bolus, not to exceed 300 mg; may be followed by continuous infusion of 1-4 mg/min.

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.
1.5–2 hours (terminal) in healthy adults; prolonged in hepatic impairment (up to 5–7 hours), heart failure (up to 10 hours), or with continuous infusion (>24 h) due to accumulation. Context: requires monitoring in hepatic or cardiac dysfunction to avoid toxicity.
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 (primarily monoethylglycinexylidide [MEGX] and glycinexylidide [GX]), <10% unchanged. Fecal: <1%.
