Cefazolin vs ROCEPHIN
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.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby interfering with peptidoglycan cross-linking and leading to cell lysis.
1-2 g IV/IM every 6-8 hours; maximum 12 g/day.
1-2 g IV or IM every 24 hours; maximum 4 g/day for serious infections.

1.8 hours in normal renal function; extends to 30–70 hours in end-stage renal disease (CrCl <10 mL/min).
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
Terminal half-life ~6-8 hours in adults with normal renal function; prolonged to 12-24 hours in neonates and elderly.
Renal: 80–90% unchanged via glomerular filtration and tubular secretion; biliary: <1%; fecal: negligible.
Renal (33-67%) and biliary (40-50%); primarily excreted unchanged. Dual elimination: ~50% renal, ~50% biliary/fecal.
