LICART vs TETRACAINE 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.
Tetracaine hydrochloride is a local anesthetic of the ester type that reversibly blocks nerve conduction by decreasing sodium ion permeability across the neuronal membrane, thereby stabilizing the membrane and preventing the initiation and transmission of nerve impulses.
Adults: 50 mg orally once daily.
Topical: 0.5-2% solution or ointment applied to affected area up to 4 times daily as needed. Maximum single dose: 20 mL of 2% solution (400 mg). Spinal anesthesia: 0.5% solution, 2-3 mL (10-15 mg) injected intrathecally.

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 1.5–3 minutes in plasma due to rapid hydrolysis; clinical effect duration is dose-dependent (15–30 minutes for topical anesthesia).
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
Primarily metabolized by plasma pseudocholinesterase; renal excretion of metabolites accounts for >95% of elimination, with <2% excreted unchanged in urine. Biliary/fecal elimination is negligible.
