LICART vs NOVOCAIN
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.
Procaine, an ester-type local anesthetic, reversibly binds to the intracellular portion of voltage-gated sodium channels, inhibiting sodium influx and blocking nerve impulse conduction.
Adults: 50 mg orally once daily.
Local infiltration: 0.5% solution, up to 20 mL (100 mg) per dose; nerve block: 1-2% solution, 5-10 mL (50-200 mg); maximum single dose: 7 mg/kg or 350 mg (without epinephrine).

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.
Plasma half-life: approximately 30–60 seconds due to rapid hydrolysis by pseudocholinesterases; clinical effects short-lived.
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 para-aminobenzoic acid (PABA) and diethylaminoethanol as major metabolites; <2% excreted unchanged in urine. Biliary/fecal: minimal.
