GEOCILLIN vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Geocillin (carbenicillin indanyl sodium) is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It exhibits bactericidal activity against susceptible gram-negative and gram-positive bacteria.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and activating autolytic enzymes.
250-500 mg orally every 6 hours.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).

1.2 hours (normal renal function); prolonged to 7-10 hours in severe renal impairment (CrCl <10 mL/min).
0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Primarily renal (70-80% unchanged via tubular secretion and glomerular filtration); minor biliary/fecal (<5%).
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
