CEFAZOLIN IN DEXTROSE vs TAZIDIME
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 disrupting peptidoglycan cross-linking.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
1-2 g IV every 8 hours. For serious infections, up to 2 g IV every 6 hours.
1 to 2 g IV/IM every 8 hours; maximum 6 g/day.

1.8 hours in normal renal function. Prolonged to 12-24 hours in end-stage renal disease (CrCl <10 mL/min).
Clinical Note
moderateCeftazidime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Ceftazidime."
Clinical Note
moderateCeftazidime + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Ceftazidime."
Clinical Note
moderateWarfarin + Ceftazidime
"Warfarin may increase the anticoagulant activities of Ceftazidime."
Clinical Note
moderatePhenprocoumon + Ceftazidime
1.9 hours (range 1.5-2.8 hours); prolonged in renal impairment (up to 20 hours in ESRD).
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: minor (<1%). Fecal: negligible.
Primarily renal (80-90% unchanged via glomerular filtration), biliary/fecal <5%.
