AUGMENTIN '125' vs PENICILLIN G POTASSIUM IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and autolysin activation. Clavulanate is a beta-lactamase inhibitor that irreversibly binds to and inactivates beta-lactamases, preventing hydrolysis of amoxicillin.
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.
One AUGMENTIN '125' tablet (amoxicillin 125 mg, clavulanate 31.25 mg) orally every 8 hours for mild to moderate infections.
2-4 million units IV every 4 hours for moderate to severe infections; up to 24 million units/day for serious infections (meningitis, endocarditis).

Amoxicillin: 1.0-1.3 hours (prolonged in renal impairment; up to 7-20 hours in anuria). Clavulanate: 0.9-1.2 hours (increased in renal impairment).
0.5–1 hour (normal renal function). Prolonged in renal impairment (up to 7–10 hours in anuria).
Amoxicillin: ~50-70% excreted unchanged in urine via glomerular filtration and tubular secretion; clavulanate: ~30-50% excreted unchanged in urine. Small amounts eliminated in bile and feces.
Renal: 60–90% unchanged via tubular secretion and glomerular filtration. Biliary/fecal: <10%.
