LICART vs PROCAINE HYDROCHLORIDE
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.
Blocks voltage-gated sodium channels, inhibiting nerve impulse conduction by stabilizing the neuronal membrane and preventing depolarization.
Adults: 50 mg orally once daily.
Local infiltration: 0.5% solution, up to 200 mg (40 mL) per dose. Nerve block: 0.5% solution, 100-200 mg (20-40 mL) per dose. Intravenous regional anesthesia (Bier block): 0.5% solution, 50-100 mg (10-20 mL) per dose. Maximum total dose: 200 mg without epinephrine, 250 mg with epinephrine 1:200,000.

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 approximately 7.7 minutes in adults with normal hepatic function. This short half-life reflects rapid hydrolysis by plasma pseudocholinesterases. In patients with pseudocholinesterase deficiency, half-life may be prolonged to 20-30 minutes.
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
Primarily renal excretion of metabolites (para-aminobenzoic acid and diethylaminoethanol) and unchanged drug. Approximately 80% of a dose is excreted in urine as para-aminobenzoic acid and conjugates; <2% excreted unchanged. Biliary/fecal elimination is negligible.
