Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G benzathine is a slow-release parenteral formulation of penicillin G that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation, and activating autolytic enzymes.
Carbenicillin is a bactericidal penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking.

0.5-1 hour; prolonged in renal impairment (up to 20 hours in severe cases).
30-60 minutes in normal renal function; prolonged to 2-4 hours in moderate renal impairment (CrCl 10-30 mL/min) and up to 10 hours in severe renal failure.
Renal: approx. 60-80% unchanged by glomerular filtration and tubular secretion. Biliary/fecal: minor (less than 10%).
Primarily renal (60-90% unchanged via glomerular filtration and tubular secretion); small amounts biliary (10-30%) and fecal (<10%).
