LICART vs ZYNRELEF KIT
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.
Zynrelef is a fixed-dose combination of bupivacaine and meloxicam. Bupivacaine blocks sodium channels in neuronal membranes, inhibiting nerve impulse conduction. Meloxicam inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis and inflammation.
Adults: 50 mg orally once daily.
Instillation into the surgical site: 20 mL (300 mg bupivacaine and 9.3 mg meloxicam) as a single dose.

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 half-life of bupivacaine (component) is 3.5 hours; for meloxicam (component) is 20 hours. Clinical context: bupivacaine half-life prolonged in hepatic impairment; meloxicam half-life prolonged in elderly (up to 25 hours)
Primarily renal excretion (80-85% as unchanged drug), with 10-15% biliary/fecal elimination. Less than 5% metabolized to inactive glucuronide conjugate.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
