Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity essential for peptidoglycan cross-linking.
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.
1-2 g intravenously every 4 hours.
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.

30-60 minutes (mean 40 min) in adults with normal renal function; prolonged to 7-10 hours in anuria. Clinical context: dosing interval adjustment required in renal impairment.
Terminal elimination half-life: 0.5–1 hour (prolonged in renal impairment); clinical context: requires probenecid for extended action
Primarily renal (60-70% unchanged by tubular secretion and glomerular filtration); biliary/fecal excretion accounts for <30%.
