BUPIVACAINE HYDROCHLORIDE PRESERVATIVE FREE vs LICART
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bupivacaine blocks voltage-gated sodium channels on neuronal membranes, inhibiting the propagation of action potentials and resulting in local anesthesia.
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.
0.25-0.5% solution, up to 2 mg/kg (max 150 mg) per dose via infiltration, peripheral nerve block, or epidural; may repeat every 3-6 hours as needed. For epidural: 0.5% solution, 15-20 mL for surgical anesthesia.
Adults: 50 mg orally once daily.

Terminal elimination half-life is 2.7 hours (range 1.5-5.5 hours). Prolonged up to 8-10 hours in neonates and 24-48 hours in severe hepatic impairment.
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.
Renal excretion accounts for approximately 95% of the dose, with about 50% excreted unchanged. The remainder is primarily hepatic metabolism followed by renal elimination of metabolites. Biliary/fecal excretion is minimal (<5%).
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
