CEFTRIAXONE IN PLASTIC CONTAINER vs CEPHALEXIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ceftriaxone inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis mediated by autolytic enzymes. It has broad-spectrum activity against gram-positive and gram-negative bacteria.
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 intravenously or intramuscularly every 12-24 hours, maximum 4 g daily.
Oral: 250-1000 mg every 6 hours; maximum 4 g/day.

5.8-8.7 hours in adults; prolonged in neonates (18-25 h), elderly, and renal impairment.
0.5-1.2 hours in normal renal function; prolonged to 5-30 hours in severe renal impairment (CrCl <10 mL/min)
