DORIBAX vs VABOMERE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Doripenem is a carbapenem antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has broad-spectrum activity against Gram-positive, Gram-negative, and anaerobic bacteria.
Vabomere is a combination of meropenem, a carbapenem antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), and vaborbactam, a beta-lactamase inhibitor that protects meropenem from degradation by certain serine beta-lactamases, including extended-spectrum beta-lactamases (ESBLs) and Klebsiella pneumoniae carbapenemase (KPC).
1 g IV every 8 hours over 1 hour for complicated intra-abdominal infections, complicated urinary tract infections (including pyelonephritis), and hospital-acquired pneumonia (including ventilator-associated pneumonia).
Vabomere (meropenem and vaborbactam) 4 g (meropenem 2 g and vaborbactam 2 g) intravenously every 8 hours infused over 3 hours.

Terminal elimination half-life approximately 1 hour in healthy adults; prolonged to ~4 hours in renal impairment (CrCl <30 mL/min).
The terminal elimination half-life is approximately 1 hour for meropenem and 2 hours for vaborbactam in patients with normal renal function. This short half-life supports three-times-daily dosing in patients with creatinine clearance ≥50 mL/min.
Renal: approximately 70-75% unchanged in urine; biliary/fecal: minimal (less than 20% total, primarily as metabolite).
Vabomere (meropenem and vaborbactam) is primarily excreted renally. Approximately 40-50% of meropenem and 75-95% of vaborbactam are excreted unchanged in urine. Biliary/fecal excretion is minimal (<2% for both).
