CEFTAZIDIME vs ROCEPHIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftazidime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has broad-spectrum activity against Gram-negative bacteria, including Pseudomonas aeruginosa.
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 every 8 hours
1-2 g IV or IM every 24 hours; maximum 4 g/day for serious infections.

2 hours (range 1.2-2.2 h) in normal renal function; prolonged to 10-15 h in end-stage renal disease; requires dose adjustment.
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
Terminal half-life ~6-8 hours in adults with normal renal function; prolonged to 12-24 hours in neonates and elderly.
Primarily renal: 80-90% excreted unchanged in urine via glomerular filtration; small amount (≈1%) biliary; ≤1% fecal.
Renal (33-67%) and biliary (40-50%); primarily excreted unchanged. Dual elimination: ~50% renal, ~50% biliary/fecal.
