EMBLAVEO vs HEPARIN LOCK FLUSH
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
EMBLAVEO is a combination of a beta-lactam antibiotic (cefepime) and a beta-lactamase inhibitor (enmetazobactam). Enmetazobactam inhibits a broad range of beta-lactamases, including ESBLs and AmpC, thereby protecting cefepime from hydrolysis and extending its spectrum of activity against beta-lactamase-producing Gram-negative bacteria.
Heparin potentiates the activity of antithrombin III, inactivating thrombin and activated factor X (FXa), thereby preventing fibrin formation and thrombus propagation.
EMBLAVEO (imipenem/cilastatin/relebactam) is administered intravenously. The recommended adult dose is 1.25 g (imipenem 500 mg, cilastatin 500 mg, relebactam 250 mg) every 6 hours infused over 30 minutes.
10-100 units/mL solution, 1-2 mL flush intravascularly after each catheter use or daily when catheter is not in use; typical adult dose: 10-100 units per flush.

Terminal elimination half-life is 11–12 hours in healthy adults; prolonged to 20–30 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life approximately 1-2 hours (mean 1.5 hours) at therapeutic doses; increases with dose; in renal failure, half-life prolonged up to 3-5 hours; clinical note: duration of effect short due to rapid clearance, requiring continuous infusion or frequent dosing.
Renal excretion of unchanged drug accounts for approximately 30% of the dose; biliary/fecal elimination accounts for about 70% (60% fecal as parent drug and metabolites, 10% biliary).
Primarily renal via glomerular filtration and tubular secretion; about 50% excreted unchanged in urine; remainder metabolized in the liver and reticuloendothelial system (heparinase); fecal elimination negligible (<5%).
