NALLPEN IN PLASTIC CONTAINER vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nallpen is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically active against beta-lactamase-producing Staphylococcus aureus.
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.
Nafcillin 1-2 g IV every 4 hours for moderate to severe infections; for MSSA bacteremia or endocarditis, 2 g IV every 4 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).

0.9-1.2 hours; prolonged in renal impairment (up to 7-10 hours in anuria); requires dose adjustment for CrCl <30 mL/min
0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Primarily renal (60-80% unchanged drug via glomerular filtration and tubular secretion); biliary/fecal: minor (<5%)
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
