LICART vs LIDOCAINE AND PRILOCAINE
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 and prilocaine are amide-type local anesthetics that stabilize neuronal membranes by inhibiting sodium ion channels, thereby blocking the initiation and conduction of nerve impulses.
Adults: 50 mg orally once daily.
Apply 2.5 g cream (lidocaine 25 mg/prilocaine 25 mg) to intact skin under occlusive dressing; maximum single application area 400 cm², maximum application time 4 hours. For genital mucous membranes: apply 5-10 g for 5-10 minutes without occlusion. Not recommended for dental use.

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.
Lidocaine: 1.5-2 hours; prilocaine: 1.5-2 hours. In hepatic impairment, half-life may be prolonged up to 2-3 times.
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 (lidocaine: 70-80% as 4-hydroxy-2,6-xylidine and conjugates; prilocaine: 85-95% as o-toluidine metabolites and conjugates). Less than 10% of parent drugs excreted unchanged.
