CEFIZOX vs ULTRACEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefizox (ceftizoxime) is a third-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibition.
Cefadroxil, a first-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis. It is bactericidal against susceptible organisms.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.
250 mg orally every 6 hours or 500 mg orally every 12 hours for uncomplicated urinary tract infections; 1 g orally every 12 hours for complicated urinary tract infections.

1.7-1.9 hours in adults; prolonged to 15-25 hours in severe renal impairment (CrCl <10 mL/min)
0.5–1.2 hours in normal renal function; prolonged to 2–4 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (90-95% unchanged via glomerular filtration and tubular secretion); biliary (<1%); fecal (minimal)
Approximately 90% of an oral dose is excreted unchanged in urine via glomerular filtration and tubular secretion; less than 1% is excreted in feces via biliary elimination.
