PENICILLIN G POTASSIUM vs VEETIDS '500'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal: inhibits transpeptidases (penicillin-binding proteins) involved in bacterial cell wall synthesis, leading to cell lysis.
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.
1-4 million units IV every 4-6 hours; maximum 24 million units/day
1 tablet (500 mg) orally twice daily for 7 days.

0.5-1 hour in normal renal function; prolonged to 3-10 hours in anuria/end-stage renal disease.
4-6 hours (prolonged in renal impairment; requires dose adjustment if CrCl <30 mL/min)
Renal (60-90% as unchanged drug via tubular secretion and glomerular filtration); biliary (minor, <10%); fecal (minimal, <5%).
Renal: 60-80% unchanged; biliary/fecal: 15-25% as metabolites
