CEPHALEXIN vs ROCEPHIN
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.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby interfering with peptidoglycan cross-linking and leading to cell lysis.
Oral: 250-1000 mg every 6 hours; maximum 4 g/day.
1-2 g IV or IM every 24 hours; maximum 4 g/day for serious 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 half-life ~6-8 hours in adults with normal renal function; prolonged to 12-24 hours in neonates and elderly.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion; biliary: <5%; fecal: <1%
Renal (33-67%) and biliary (40-50%); primarily excreted unchanged. Dual elimination: ~50% renal, ~50% biliary/fecal.
