LICART vs LIDODERM
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) in nerve cell membranes, inhibiting depolarization and conduction of nerve impulses, thereby producing both local anesthesia and systemic analgesia.
Adults: 50 mg orally once daily.
Apply 1 to 3 patches (5% lidocaine) to intact skin over most painful area for up to 12 hours within a 24-hour period; maximum 3 patches at once.

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 3–5 hours after topical application; after intravenous administration, half-life is 1.5–2 hours. Clinical context: Systemic accumulation possible with prolonged use on inflamed skin.
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 (primarily 4-hydroxy-2,6-xylidine glucuronide) accounts for >85% of elimination; <3% excreted unchanged; biliary/fecal elimination minimal (<10%).
