PENICILLIN G POTASSIUM IN PLASTIC CONTAINER vs POLYMOX
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), inhibiting transpeptidation and activating autolytic enzymes.
Amoxicillin is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and inhibiting transpeptidase activity, leading to cell lysis.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
