Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and peptidoglycan cross-linking.
1.2 million to 2.4 million units intramuscularly once daily for most infections (e.g., uncomplicated pneumonia); for neurosyphilis, 2.4 million units intramuscularly once daily plus probenecid 500 mg orally four times daily for 10-14 days. Administer deep IM injection, not IV.
250-500 mg intravenously or intramuscularly every 4-6 hours. Maximum dose 12 g per day.

Terminal elimination half-life is approximately 0.5-1 hour in patients with normal renal function. Clinically, the prolonged absorption from the intramuscular depot results in sustained serum concentrations, with effective levels lasting 12-24 hours.
0.5-1 hour (normal renal function); prolonged to 2-5 hours in renal impairment
Primarily renal excretion via tubular secretion and glomerular filtration. Approximately 60-90% of a dose is excreted unchanged in urine within 24 hours. Biliary/fecal elimination is minor (<10%).
Renal: 60-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: minor, <10%
