BUPIVACAINE LIPOSOME vs LICART
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupivacaine liposome is a long-acting local anesthetic that reversibly blocks nerve impulse propagation by inhibiting sodium ion influx through voltage-gated sodium channels in neuronal cell membranes. The liposomal formulation provides sustained release of bupivacaine, prolonging analgesic effect.
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.
Local infiltration: up to 266 mg (20 mL of 1.3% or 10 mL of 2.66%) single dose; interscalene brachial plexus block: up to 133 mg (10 mL of 1.3%) single dose; sciatic nerve block in the popliteal fossa: up to 133 mg (10 mL of 1.3%) single dose; adductor canal block: up to 133 mg (10 mL of 1.3%) single dose; max dose 266 mg per procedure.
Adults: 50 mg orally once daily.

Terminal elimination half-life is approximately 12-24 hours (mean 18 hours) due to prolonged release from liposomal depot; significantly longer than conventional bupivacaine (2-4 hours), reflecting slow absorption rate-limited elimination.
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.
Primarily hepatic metabolism to 3-hydroxybupivacaine and desbutylbupivacaine; renal excretion of metabolites accounts for ~95% of elimination, with <5% unchanged drug excreted in urine; biliary/fecal excretion minimal (<5%).
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
