AMOXICILLIN AND CLAVULANATE POTASSIUM vs DURACILLIN A.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. Clavulanate potassium is a beta-lactamase inhibitor that irreversibly inactivates beta-lactamase enzymes, preventing degradation of amoxicillin.
Penicillin G procaine is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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.
600,000 units intramuscularly once daily; or 1.2 million units intramuscularly every 12 hours for severe infections.

Amoxicillin: ~1-1.5 hours; Clavulanate: ~1 hour. Prolonged in renal impairment.
0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in end-stage renal disease
Renal: ~50-70% amoxicillin unchanged; ~25-40% clavulanate as metabolites. Fecal: minimal. Biliary: minor.
Primarily renal (60-90% unchanged via tubular secretion and glomerular filtration); minor biliary/fecal elimination (<10%)
