BETAPEN-VK vs OXACILLIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin V binds to penicillin-binding proteins (PBPs) located on the bacterial cell wall, inhibiting transpeptidase activity and disrupting peptidoglycan synthesis, leading to cell lysis.
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.
250-500 mg orally every 6 hours for mild to moderate infections; 500 mg orally every 6 hours for severe infections; up to 500 mg orally every 4 hours for severe infections.
1-2 grams IV every 4-6 hours.

0.5-1 hour in patients with normal renal function; prolonged to 7-10 hours with creatinine clearance <10 mL/min.
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)
Renal excretion accounts for 20-40% of the dose as unchanged drug via tubular secretion and glomerular filtration; biliary/fecal excretion is minimal (<10%).
Renal (70-80% unchanged by tubular secretion and glomerular filtration); biliary (minor, approximately 10%)
