AMOXICILLIN PEDIATRIC vs PROSTAPHLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin is a semisynthetic penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). It blocks the transpeptidation step in peptidoglycan cross-linking, leading to cell lysis and death.
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 8 hours or 500-875 mg orally every 12 hours for adults.
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.

Terminal elimination half-life: 1-1.5 hours in children with normal renal function; prolonged to 7-21 hours in anuria.
0.4-0.8 hours in adults with normal renal function; prolonged in renal impairment (up to 4-6 hours in anuria).
Renal: 60-80% unchanged via glomerular filtration and tubular secretion; biliary: minor (<10%); fecal: <5%.
Primarily renal (70-80% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
