Cefazolin vs KAFOCIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and disrupting peptidoglycan cross-linking. This leads to cell lysis and death primarily in susceptible gram-positive bacteria.
KAFOCIN (cefepime/enmetazobactam) is a combination of a fourth-generation cephalosporin (cefepime) and a β-lactamase inhibitor (enmetazobactam). Enmetazobactam inhibits extended-spectrum β-lactamases (ESBLs) and other class A β-lactamases, restoring cefepime's activity against β-lactamase-producing bacteria. Cefepime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell death.

Clinical Note
moderateCefazolin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Cefazolin."

"The serum concentration of Probenecid can be increased when it is combined with Cefazolin."
Clinical Note
moderateCefazolin + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefazolin."

moderatePhenytoin + Cefazolin
1.8 hours in normal renal function; extends to 30–70 hours in end-stage renal disease (CrCl <10 mL/min).
Terminal elimination half-life: 4.5-6.5 hours (increased to 12-18 hours in severe renal impairment; CrCl <30 mL/min).
Renal: 80–90% unchanged via glomerular filtration and tubular secretion; biliary: <1%; fecal: negligible.
Renal: 60-80% unchanged; biliary/fecal: 15-30% as metabolites; total clearance ~120 mL/min.
