Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation, leading to cell lysis.
Cefixime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting peptidoglycan cross-linking. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
1-2 g IV/IM every 4-6 hours; maximum 12 g/day.
400 mg orally once daily or 200 mg orally every 12 hours.

Terminal elimination half-life: 0.5-1 hour (normal renal function); prolonged to 2-3 hours in anuria. Clinically, dosing every 6 hours is recommended.
Terminal elimination half-life: 3-4 hours in normal renal function; prolonged to 11-15 hours in severe renal impairment (CrCl <20 mL/min).
Renal: 70-80% unchanged via glomerular filtration and tubular secretion; biliary: minimal (<5%); fecal: <1%.
Renal: 50-55% unchanged in urine; biliary/fecal: 10-20% (biliary excretion); remainder metabolized or excreted via feces.
