AUGMENTIN ES-600 vs BACTOCILL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AUGMENTIN ES-600 is a combination of amoxicillin, a beta-lactam antibiotic, and clavulanate, a beta-lactamase inhibitor. Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), while clavulanate irreversibly inhibits beta-lactamase enzymes, preventing degradation of amoxicillin.
BACTOCILL (nafcillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and autolysin inhibitors. Active against Staphylococcus aureus and other gram-positive bacteria.
90 mg/kg/day orally divided every 12 hours (based on amoxicillin component). Maximum 4000 mg amoxicillin/600 mg clavulanate per day.
250-500 mg orally every 6 hours or 1-2 g intravenously every 4-6 hours

Amoxicillin: ~1.0-1.5 hours in adults with normal renal function; clavulanate: ~1.0-1.2 hours. In renal impairment, half-life prolongs significantly (amoxicillin up to 7-20 hours in ESRD).
0.5-0.8 hours; prolonged to 2-4 hours in severe renal impairment
Amoxicillin: ~50-70% excreted unchanged renally via glomerular filtration and tubular secretion; clavulanate: ~25-40% excreted unchanged renally. Combined: renal excretion accounts for ~60-80% of elimination, with minor biliary/fecal elimination (approx 5-15% for amoxicillin).
Renal: 60-70% unchanged; biliary: 20-30% as active metabolite; fecal: 5-10%
