CEFADYL vs CEPHALEXIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation.
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 6 hours for moderate to severe infections; maximum 12 g/day.
Oral: 250-1000 mg every 6 hours; maximum 4 g/day.

30-60 minutes in adults with normal renal function; prolonged to 10-20 hours in end-stage renal disease. Requires dose adjustment for CrCl <30 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
0.5-1.2 hours in normal renal function; prolonged to 5-30 hours in severe renal impairment (CrCl <10 mL/min)
Renal: 90-95% unchanged via glomerular filtration and tubular secretion. Biliary: <1%. Fecal: minimal.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion; biliary: <5%; fecal: <1%
