CEFOTAXIME vs CEPHALOTHIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotaxime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
Cephalothin is a first-generation cephalosporin with bactericidal activity by inhibiting bacterial cell wall synthesis via binding to penicillin-binding proteins (PBPs).
1-2 g IV every 6-8 hours; maximum 12 g/day. For uncomplicated infections: 1 g IV every 8-12 hours.
1-2 g IV every 4-6 hours; maximum 12 g/day.

Terminal elimination half-life: 1-1.5 hours in adults with normal renal function. In neonates, it is prolonged to 2-4 hours. In severe renal impairment (CrCl <20 mL/min), half-life extends up to 10-15 hours, requiring dose adjustment.
Clinical Note
moderateCefotaxime + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cefotaxime."
Clinical Note
moderateCefotaxime + Picosulfuric acid
"The therapeutic efficacy of Picosulfuric acid can be decreased when used in combination with Cefotaxime."
Clinical Note
moderateWarfarin + Cefotaxime
"Warfarin may increase the anticoagulant activities of Cefotaxime."
Clinical Note
moderatePhenprocoumon + Cefotaxime
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.
Approximately 80-90% of the dose is excreted unchanged in the urine via glomerular filtration and tubular secretion. About 5-10% is excreted in bile and feces as desacetylcefotaxime, the active metabolite.
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion). Minor biliary excretion (1-5%). Fecal elimination negligible.
