BACTOCILL vs PROSTAPHLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BACTOCILL (nafcillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibitors. Active against Staphylococcus aureus and other gram-positive bacteria.
Prostaphlin (oxacillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), specifically PBP1 and PBP3, leading to inhibition of transpeptidation and cell lysis. It is resistant to staphylococcal beta-lactamases.
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours
250-500 mg IM or IV every 4-6 hours for moderate to severe infections. For oral use: 250-500 mg every 6 hours on empty stomach.

0.5-0.8 hours; prolonged to 2-4 hours in severe renal impairment
0.4-0.8 hours in adults with normal renal function; prolonged in renal impairment (up to 4-6 hours in anuria).
Renal: 60-70% unchanged; biliary: 20-30% as active metabolite; fecal: 5-10%
Primarily renal (70-80% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
