LICART vs LIDOCAINE 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 an amide-type local anesthetic that blocks voltage-gated sodium channels (Nav1.7, Nav1.8) in neuronal membranes, inhibiting depolarization and propagation of action potentials, thereby producing local anesthesia. It also has antiarrhythmic properties (class IB) by blocking sodium channels in cardiac myocytes.
Adults: 50 mg orally once daily.
15 mL (300 mg) orally every 3 hours as needed for pain; maximum 8 doses per 24 hours.

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 is 1.5–2 hours (up to 3 hours in hepatic impairment). Clinically, redistribution half-life (~6 min) determines duration of action after short infusions.
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 unchanged drug and metabolites accounts for >90% of elimination; <10% biliary/fecal. Metabolites include monoethylglycinexylidide (MEGX) and glycinexylidide (GX).
