CEFOTAN vs CEPHALEXIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefotetan is a cephamycin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking, and activating autolytic enzymes.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and disrupting cell wall cross-linking, leading to cell lysis and death.
1-2 g IV/IM every 12 hours for 5-10 days; up to 6 g/day for severe infections.
Oral: 250-1000 mg every 6 hours; maximum 4 g/day.

Terminal elimination half-life: 4.5 hours (intravenous). In patients with renal impairment (CrCl <30 mL/min), half-life extends to approximately 20–30 hours, requiring dose adjustment.
Clinical Note
moderateCephalexin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Cephalexin."
Clinical Note
moderateCephalexin + Haloperidol
"The metabolism of Haloperidol can be decreased when combined with Cephalexin."
Clinical Note
moderateCephalexin + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Cephalexin."
Clinical Note
moderateCephalexin + Sulfisoxazole
0.5-1.2 hours in normal renal function; prolonged to 5-30 hours in severe renal impairment (CrCl <10 mL/min)
Primarily renal (unchanged); ~88% excreted in urine within 24 hours. Biliary/fecal elimination is negligible (<1% as metabolites).
Renal: 80-90% unchanged by glomerular filtration and tubular secretion; biliary: <5%; fecal: <1%
