Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G benzathine is a slow-release parenteral formulation of penicillin G that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
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 mg orally every 6 hours or 500 mg orally every 12 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.

0.5-1 hour; prolonged in renal impairment (up to 20 hours in severe cases).
0.4-0.8 hours in adults with normal renal function; prolonged in renal impairment (up to 4-6 hours in anuria).
Renal: approx. 60-80% unchanged by glomerular filtration and tubular secretion. Biliary/fecal: minor (less than 10%).
Primarily renal (70-80% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
