Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cefotaxime is a third-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), blocking transpeptidation, and activating autolytic enzymes.
Oral: 250-1000 mg every 6 hours; maximum 4 g/day.
1-2 g IV/IM every 8-12 hours; maximum 12 g/day for severe infections.

0.5-1.2 hours in normal renal function; prolonged to 5-30 hours in severe renal impairment (CrCl <10 mL/min)
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
Terminal elimination half-life is approximately 0.6-1.2 hours in adults with normal renal function. In neonates, it is prolonged (2-6 hours). In renal impairment, half-life extends significantly (up to 15-30 hours in anuria), requiring dose adjustment.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion; biliary: <5%; fecal: <1%
Primarily renal: approximately 60-80% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion. Small amounts are eliminated in bile (<10%) and feces (<1%).
