GEOCILLIN vs POLYMOX
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.
Amoxicillin is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and inhibiting transpeptidase activity, leading to cell lysis.

250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

1.2 hours (normal renal function); prolonged to 7-10 hours in severe renal impairment (CrCl <10 mL/min).
Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Primarily renal (70-80% unchanged via tubular secretion and glomerular filtration); minor biliary/fecal (<5%).
