AUGMENTIN '125' vs PENBRITIN-S
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.
Penicillinase-sensitive penicillin; inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
One AUGMENTIN '125' tablet (amoxicillin 125 mg, clavulanate 31.25 mg) orally every 8 hours for mild to moderate infections.
250-500 mg orally every 6 hours or 500 mg-1 g intramuscularly/intravenously every 4-6 hours for moderate to severe infections.

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; 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: 75-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: ~10%.
