LICART vs POLOCAINE-MPF
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.
Polocaine-MPF (mepivacaine hydrochloride) is an amide-type local anesthetic that blocks sodium ion channels in nerve cell membranes, thereby preventing the initiation and propagation of nerve impulses. This results in reversible loss of sensation in the area of administration.
Adults: 50 mg orally once daily.
Adults: 1-2 cartridges (1.8 mL each) of 2% lidocaine with 1:100,000 epinephrine administered via local infiltration or nerve block, not to exceed 7 mg/kg (maximum 500 mg) for lidocaine.

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: 1.5-2.0 hours in adults; prolonged in hepatic impairment (up to 4-6 hours) and severe renal impairment. Clinical context: short half-life supports continuous infusion for sustained effect.
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 4-hydroxy-2',6'-dimethylacetanilide and pipecoloxylidide; unchanged drug <5%. Biliary/fecal: <5%.
