AMCILL vs CYCLAPEN-W
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.
Cyclacillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It has a similar spectrum to ampicillin but with increased acid stability and oral absorption.
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 for mild to moderate infections; 500 mg orally every 6 hours for severe infections.

1-1.5 hours in normal renal function; prolonged to 7-10 hours in anuria.
0.5-1 hour in adults with normal renal function; prolonged to 2-6 hours in renal impairment.
Renal: 60-80% unchanged; biliary: less than 10%; fecal: small amount.
Primarily renal (90-100% unchanged via glomerular filtration and tubular secretion); minor biliary/fecal elimination (<10%).
