CEFTAZIDIME vs DOCEFREZ
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.
Docetaxel binds to beta-tubulin, promoting microtubule assembly and inhibiting depolymerization, resulting in cell cycle arrest at G2/M phase and apoptosis.

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 elimination half-life is 4.5-6.0 hours in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal: 80-90% excreted unchanged in urine via glomerular filtration; small amount (≈1%) biliary; ≤1% fecal.
Primarily renal excretion (70-80% as unchanged drug) with hepatic metabolism contributing to biliary/fecal elimination (20-30%).
