Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
2 g intravenously every 6 hours for susceptible infections.

1-1.5 hours in normal renal function; prolonged to 7-10 hours in anuria.
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).
Renal: 60-80% unchanged; biliary: less than 10%; fecal: small amount.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: <2%.
