CEFTRIAXONE IN PLASTIC CONTAINER vs VELOSEF '125'
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), inhibiting peptidoglycan cross-linking, leading to cell lysis.
1-2 g intravenously or intramuscularly every 12-24 hours, maximum 4 g daily.
500 mg orally every 6 hours for uncomplicated infections; 1 g orally every 6 hours for more severe infections.

5.8-8.7 hours in adults; prolonged in neonates (18-25 h), elderly, and renal impairment.
Terminal elimination half-life: 0.5-1.0 hour (normal renal function); prolonged to 10-20 hours in severe renal impairment (CrCl <10 mL/min)
Renal (33-67% as unchanged drug), biliary/fecal (24-44% as active drug and metabolites).
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: <5%
