NALLPEN IN PLASTIC CONTAINER vs PENTIDS '400'
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 binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and disrupting peptidoglycan cross-linking, leading to cell lysis.
Nafcillin 1-2 g IV every 4 hours for moderate to severe infections; for MSSA bacteremia or endocarditis, 2 g IV every 4 hours.
400 mg orally every 6 hours.

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 in patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Primarily renal (60-80% unchanged drug via glomerular filtration and tubular secretion); biliary/fecal: minor (<5%)
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.
