AUGMENTIN ES-600 vs BICILLIN C-R
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.
Benzathine penicillin G and procaine penicillin G are beta-lactam antibiotics that inhibit bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and activating autolytic enzymes, leading to cell lysis.
90 mg/kg/day orally divided every 12 hours (based on amoxicillin component). Maximum 4000 mg amoxicillin/600 mg clavulanate per day.
1.2 million units intramuscularly as a single dose (600,000 units procaine penicillin G and 600,000 units benzathine penicillin G) for moderate to severe infections; for mild infections, 600,000 units intramuscularly as a single dose.

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).
Penicillin G: 0.5-1 hour in normal renal function; prolonged to 7-10 hours in anuria. Benzathine component sustains low levels for days; effective half-life of benzathine penicillin G is 3-5 days due to slow release.
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 excretion primarily via glomerular filtration and tubular secretion; approximately 60-70% of penicillin G is excreted unchanged in urine within 6 hours; benzathine and procaine components are metabolized and excreted renally as well; small amounts in bile and feces.
