CEFIXIME vs CEPHAPIRIN SODIUM
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.
Cephapirin sodium is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP1 and PBP3, thereby inhibiting transpeptidation and disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes.
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
500 mg to 1 g IM or IV every 6 hours.

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 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.
0.5-1.0 hours; prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Renal excretion of unchanged drug accounts for 50-60% of elimination; biliary/fecal elimination accounts for 10-20%.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%.
