CEFPROZIL vs TAZIDIME
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefprozil, a second-generation cephalosporin, exerts bactericidal activity by binding to penicillin-binding proteins (PBPs) and inhibiting bacterial cell wall synthesis, leading to cell lysis.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
250-500 mg orally every 12 hours for 10 days; for pharyngitis/tonsillitis: 500 mg orally every 24 hours for 10 days.
1 to 2 g IV/IM every 8 hours; maximum 6 g/day.

1.2-1.4 hours in adults with normal renal function; prolonged to 5-6 hours in severe renal impairment (CrCl <30 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."

moderateCefprozil + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefprozil."
Clinical Note
moderateWarfarin + Ceftazidime
1.9 hours (range 1.5-2.8 hours); prolonged in renal impairment (up to 20 hours in ESRD).
Renal (primarily), approximately 60-70% unchanged in urine; biliary/fecal excretion accounts for <10%.
Primarily renal (80-90% unchanged via glomerular filtration), biliary/fecal <5%.
