PENTIDS '800' vs POLYCILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), transpeptidases that catalyze the final transpeptidation step of peptidoglycan cross-linking, leading to cell lysis.
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.
800 mg orally every 6 to 8 hours; maximum 4 g per day.
250-500 mg orally every 6 hours or 500 mg intravenously every 4-6 hours for moderate to severe infections.

0.5-1 hour; prolonged to 2-5 hours in renal impairment.
Terminal elimination half-life is 0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in anuria.
Renal: ~60-85% unchanged via glomerular filtration and tubular secretion; Biliary: ~10%; Fecal: <5%.
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.
