Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Carbenicillin is a bactericidal penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has activity against Gram-negative and some Gram-positive bacteria.
Amoxicillin is a semisynthetic penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
2 g intravenously every 6 hours for susceptible infections.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours for 7-14 days; maximum 4 g/day.

Terminal half-life 4-6 hours in normal renal function; prolonged to 10-20 hours in moderate renal impairment (CrCl 10-50 mL/min) and up to 30-50 hours in severe impairment (CrCl <10 mL/min).
0.7-1.4 hours (mean ~1 hour) in adults with normal renal function; prolonged to 2-6 hours in anuria.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <2%.
Renal: 60-70% unchanged via glomerular filtration and tubular secretion; biliary: <5%; fecal: <5%.
