OMNIPEN-N vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Omnipen-N (ampicillin sodium) is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby interfering with transpeptidation and resulting in cell lysis.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and activating autolytic enzymes.
250-500 mg orally every 6 hours for adults; for severe infections, up to 1 g every 6 hours.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).

30-60 minutes (normal renal function); prolonged to 7-10 hours in severe renal impairment (CrCl <10 mL/min).
0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Primarily renal (80-90% unchanged via tubular secretion); minor biliary/fecal (<10%).
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
