LICART vs LIDOCAINE
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 sodium channel blocker that inhibits the influx of sodium ions into cardiac Purkinje fibers and myocytes, thereby stabilizing the neuronal membrane and decreasing automaticity. It also exhibits local anesthetic effects by reversibly binding to voltage-gated sodium channels in nerve cell membranes, blocking impulse conduction.
Adults: 50 mg orally once daily.
For ventricular arrhythmias: IV bolus 1-1.5 mg/kg, then continuous infusion 1-4 mg/min. For local anesthesia: 0.5-2% solution, max 4.5 mg/kg (300 mg) without epinephrine, 7 mg/kg (500 mg) with epinephrine.

moderateLidocaine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Lidocaine is combined with Fluticasone propionate."

moderateLidocaine + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Lidocaine."
Clinical Note
moderateLidocaine + Erythromycin
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 (normal hepatic function). In CHF or hepatic impairment, prolonged to 6-8 hours; in neonates, 3-6 hours. Context: rapid redistribution after IV bolus (alpha half-life ~8 min) accounts for brief clinical effect, while terminal half-life determines accumulation with infusion.
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: 4-hydroxyxylidine (70-80% renal, 10-20% biliary/fecal), unchanged lidocaine <10% renal. Total renal elimination ~90% (as metabolites), biliary/fecal ~10%.
