OXACILLIN SODIUM vs PENTIDS '400'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxacillin is a penicillinase-resistant beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking the transpeptidation step in peptidoglycan cross-linking. It is resistant to staphylococcal beta-lactamase.
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 grams IV every 4-6 hours.
400 mg orally every 6 hours.

0.3-0.8 hours in adults with normal renal function; prolonged to 1-2 hours in neonates and 2-5 hours in patients with severe renal impairment (CrCl <10 mL/min)
0.5-1 hour in patients with normal renal function. Prolonged to 2-5 hours in renal impairment, requiring dose adjustment.
Renal (70-80% unchanged by tubular secretion and glomerular filtration); biliary (minor, approximately 10%)
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.
