BICILLIN vs VEETIDS '500'
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzathine penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and autolysin inhibition, 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.
Benzathine penicillin G 1.2 million units intramuscularly once for early syphilis; 2.4 million units intramuscularly weekly for 3 weeks for late latent syphilis.
1 tablet (500 mg) orally twice daily for 7 days.

Terminal elimination half-life: 0.5–1 hour (prolonged in renal impairment); clinical context: requires probenecid for extended action
4-6 hours (prolonged in renal impairment; requires dose adjustment if CrCl <30 mL/min)
Primarily renal (60–70% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%)
Renal: 60-80% unchanged; biliary/fecal: 15-25% as metabolites
