CEFIXIME vs CEPHALOTHIN 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.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
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
1-2 g IV every 4-6 hours; maximum 12 g/day.

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: 0.5-1.0 hour in adults with normal renal function. In anuria, prolonged to 2.5-8 hours. Dose adjustment required for CrCl <50 mL/min.
Renal excretion of unchanged drug accounts for 50-60% of elimination; biliary/fecal elimination accounts for 10-20%.
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
