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.
Penicillin G benzathine and penicillin G procaine are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis via autolytic enzymes. Synergistic action covers both susceptible Gram-positive cocci (e.g., Streptococcus pyogenes) and some Gram-negative cocci (e.g., Neisseria spp.).
1-2 g intravenously every 4 hours.
Intramuscular injection: 1.2 mL (900,000 units penicillin G benzathine and 300,000 units penicillin G procaine) every 48 hours for 3 doses; for severe infections, up to 2.4 mL (1,800,000/600,000 units) as a single dose.

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.
0.5-1 hour for penicillin G; prolonged to 3-6 hours in renal impairment. Procaine component has no significant effect on elimination half-life
Primarily renal (60-70% unchanged by tubular secretion and glomerular filtration); biliary/fecal excretion accounts for <30%.
Renal: 60-90% as unchanged drug; biliary/fecal: minor (less than 10%)
