AMCILL vs POLYCILLIN
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.
Polycillin (ampicillin) is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
250-500 mg orally every 6 hours or 500 mg intravenously every 4-6 hours for moderate to severe infections.

1-1.5 hours in normal renal function; prolonged to 7-10 hours in anuria.
Terminal elimination half-life is 0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in anuria.
Renal: 60-80% unchanged; biliary: less than 10%; fecal: small amount.
Renal excretion of unchanged drug accounts for 60-80% via glomerular filtration and tubular secretion; 20-40% is hepatically metabolized and eliminated in bile/feces.
