Cefazolin vs CEFOBID
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.
Cefoperazone is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking and causing cell lysis.
1-2 g IV/IM every 6-8 hours; maximum 12 g/day.
2-4 g/day IV/IM divided q12h; severe infections: 6-12 g/day IV divided q8-12h

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).
2 hours (prolonged in hepatic impairment and neonates).
Renal: 80–90% unchanged via glomerular filtration and tubular secretion; biliary: <1%; fecal: negligible.
Primarily renal (80-90% unchanged in urine) and biliary (10-20%).
