AUGMENTIN '250' vs PENICILLIN G SODIUM
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), disrupting peptidoglycan cross-linking. Clavulanate is a beta-lactamase inhibitor that irreversibly binds to beta-lactamases, preventing hydrolysis of amoxicillin.
Penicillin G inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes.
One 250 mg amoxicillin/125 mg clavulanate tablet orally every 8 hours for 7-10 days.
2-4 million units intravenously every 4 hours for moderate to severe infections; up to 24 million units/day for severe infections (e.g., meningitis, endocarditis).

Amoxicillin: 1.0-1.3 hours; clavulanate: 1.0-1.5 hours; prolonged in renal impairment (up to 7 hours for amoxicillin in anuria).
30-60 minutes in normal renal function; prolonged to 7-10 hours in anuria.
Renal: ~50-70% as amoxicillin, ~25-40% as clavulanate unchanged; biliary/fecal: minor (10-15% combined).
Primarily renal (60-90% unchanged) via glomerular filtration and tubular secretion; minor biliary/fecal (<10%).
