Cefazolin vs CEFOTETAN AND DEXTROSE IN DUPLEX CONTAINER
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.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), resulting in cell lysis and death.
1-2 g IV/IM every 6-8 hours; maximum 12 g/day.
1 to 2 g intravenously every 12 hours for 5 to 10 days. For severe infections, 2 g intravenously every 12 hours.

Clinical Note
moderateCefazolin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Cefazolin."
Clinical Note
moderateCefazolin + Probenecid
"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."
Clinical Note
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 3-4 hours in normal renal function; prolonged in renal impairment (e.g., up to 13 hours in severe renal failure).
Renal: 80–90% unchanged via glomerular filtration and tubular secretion; biliary: <1%; fecal: negligible.
Primarily renal (unchanged drug) ~88%; minor biliary/fecal ~6-9%.
