PROSTAPHLIN vs VEETIDS '500'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
VEETIDS '500' (cefuroxime axetil) is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking transpeptidation and leading to cell lysis. It has activity against both gram-positive and gram-negative bacteria.
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.
1 tablet (500 mg) orally twice daily for 7 days.

0.4-0.8 hours in adults with normal renal function; prolonged in renal impairment (up to 4-6 hours in anuria).
4-6 hours (prolonged in renal impairment; requires dose adjustment if CrCl <30 mL/min)
Primarily renal (70-80% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
Renal: 60-80% unchanged; biliary/fecal: 15-25% as metabolites
