EXBLIFEP vs KETEK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Exblifep is a beta-lactamase inhibitor combination consisting of cefepime, a cephalosporin antibacterial, and enmetazobactam, a beta-lactamase inhibitor. Enmetazobactam inhibits Ambler class A and some class C beta-lactamases, restoring cefepime activity against beta-lactamase-producing Enterobacterales.
Telithromycin binds to the 50S subunit of bacterial ribosome, inhibiting protein synthesis by blocking peptide chain elongation.
2.5 g (cefepime 2 g, enmetazobactam 0.5 g) intravenously every 8 hours infused over 2 hours.
Telithromycin 800 mg orally once daily for 7-10 days.

The terminal elimination half-life of Exblifep is approximately 8-10 hours in patients with normal renal function. In patients with renal impairment, half-life is prolonged and dosing adjustments are required.
Terminal half-life (t½) is 9.8–10.6 hours in young healthy adults, allowing once-daily dosing. In elderly or severe hepatic impairment, t½ may be prolonged.
Exblifep is primarily excreted renally as unchanged drug (approximately 60-70% of the dose) and as the active metabolite nifepristone (approximately 20-30%). Fecal excretion accounts for <10% of the dose. Biliary excretion is minimal.
Primarily fecal (≈70%) via biliary excretion of unchanged drug; renal excretion accounts for ≈13% (mostly unchanged), with additional minor metabolism (<30%).
