AMPICILLIN SODIUM vs PENTIDS '400'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Penicillin G binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking, leading to cell lysis.
1-2 g IV/IM every 4-6 hours for serious infections; maximum 12 g/day.
400 mg orally every 6 hours.

Terminal elimination half-life ~1 hour in healthy adults; prolonged to 2–5 hours in renal impairment (CrCl <10 mL/min) and up to 7–20 hours in anuria; neonatal half-life 2–4 hours.
0.5-1 hour in patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Approximately 90% renal excretion via tubular secretion and glomerular filtration; small biliary excretion (<10%); fecal elimination negligible.
Primarily renal (tubular secretion and glomerular filtration); 60-90% of dose excreted unchanged in urine within 24 hours. Minor biliary excretion (<10%) and fecal elimination.
