AMCILL vs NALLPEN IN PLASTIC CONTAINER
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.
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.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
Nafcillin 1-2 g IV every 4 hours for moderate to severe infections; for MSSA bacteremia or endocarditis, 2 g IV every 4 hours.

1-1.5 hours in normal renal function; prolonged to 7-10 hours in anuria.
0.9-1.2 hours; prolonged in renal impairment (up to 7-10 hours in anuria); requires dose adjustment for CrCl <30 mL/min
Renal: 60-80% unchanged; biliary: less than 10%; fecal: small amount.
Primarily renal (60-80% unchanged drug via glomerular filtration and tubular secretion); biliary/fecal: minor (<5%)
