CEPHALEXIN vs TAZIDIME IN PLASTIC CONTAINER
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.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP-3, leading to cell lysis and death. It is a beta-lactam antibiotic with activity against Gram-negative bacteria including Pseudomonas aeruginosa.
Oral: 250-1000 mg every 6 hours; maximum 4 g/day.
1-2 g intravenously every 8 hours for most infections; up to 2 g every 6 hours for severe infections, particularly in neutropenic patients or those with cystic fibrosis.

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)
Terminal elimination half-life 1.7-2.0 hours in adults with normal renal function; prolonged to 12-30 hours in end-stage renal disease.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion; biliary: <5%; fecal: <1%
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <1%.
