AMOXICILLIN AND CLAVULANATE POTASSIUM vs AUGMENTIN '200'
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. Clavulanate potassium is a beta-lactamase inhibitor that irreversibly inactivates beta-lactamase enzymes, preventing degradation of amoxicillin.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), while clavulanate irreversibly inhibits beta-lactamases, preventing degradation of amoxicillin.
500 mg amoxicillin/125 mg clavulanate orally every 8 hours or 875 mg amoxicillin/125 mg clavulanate orally every 12 hours. For severe infections: 875 mg amoxicillin/125 mg clavulanate orally every 8 hours or 1000 mg amoxicillin/62.5 mg clavulanate extended-release orally every 12 hours.
One 200 mg amoxicillin/28.5 mg clavulanate chewable tablet every 8 hours for mild to moderate infections; for severe infections, one 400 mg/57 mg tablet every 12 hours or one 200 mg/28.5 mg tablet every 8 hours.

Amoxicillin: ~1-1.5 hours; Clavulanate: ~1 hour. Prolonged in renal impairment.
Amoxicillin: ~1 hour in healthy adults, prolonged to 7-20 hours in renal impairment (CrCl <10 mL/min). Clavulanate: ~1 hour, similarly prolonged in renal impairment. The combination's half-life supports twice-daily dosing for most infections.
Renal: ~50-70% amoxicillin unchanged; ~25-40% clavulanate as metabolites. Fecal: minimal. Biliary: minor.
Amoxicillin: ~50-70% excreted unchanged in urine via glomerular filtration and tubular secretion, with the remainder hepatically metabolized and excreted in bile and feces. Clavulanate: ~30-50% excreted unchanged in urine, the rest metabolized and eliminated in bile and feces.
