CEFIXIME vs ZINACEF
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefixime 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.
Cefuroxime, a second-generation cephalosporin, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.
400 mg orally once daily or 200 mg orally every 12 hours for 7–14 days; uncomplicated gonorrhea: 400 mg orally as a single dose
750 mg IV/IM every 8 hours; for severe infections: 1.5 g IV every 8 hours; for life-threatening infections: 1.5 g IV every 6 hours

Terminal elimination half-life is 3-4 hours in patients with normal renal function; extends to 11-15 hours in moderate renal impairment (CrCl 20-40 mL/min) and up to 20 hours in severe impairment.
Clinical Note
moderateCefixime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefixime."
Clinical Note
moderateCefixime + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefixime."
Clinical Note
moderateWarfarin + Cefixime
"Warfarin may increase the anticoagulant activities of Cefixime."
Clinical Note
moderatePhenprocoumon + Cefixime
Terminal elimination half-life: 1.5-2 hours in adults with normal renal function; prolonged to 2.5-3.5 hours in elderly and up to 48 hours in end-stage renal disease.
Renal excretion of unchanged drug accounts for 50-60% of elimination; biliary/fecal elimination accounts for 10-20%.
Renal: 80-95% unchanged via glomerular filtration and tubular secretion; biliary: 5-10% excreted in feces; fecal: negligible.
