Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Amoxicillin is a semisynthetic aminopenicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidation and disrupting cell wall integrity, leading to bacteriolysis. Clavulanate is a beta-lactamase inhibitor that irreversibly binds to and inactivates a broad range of beta-lactamases, preventing degradation of amoxicillin and extending its spectrum to include beta-lactamase-producing bacteria.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
1 tablet (amoxicillin 500 mg / clavulanate 125 mg) orally every 8 hours or 1 tablet (amoxicillin 875 mg / clavulanate 125 mg) orally every 12 hours for mild to moderate infections. For severe infections, use 875 mg/125 mg every 12 hours.

1-1.5 hours in normal renal function; prolonged to 7-10 hours in anuria.
Amoxicillin: 1-1.3 hours; clavulanate: 1 hour. In renal impairment (CrCl <30 mL/min): amoxicillin 7-20 hours, clavulanate 4-6 hours. Extends dosing interval.
Renal: 60-80% unchanged; biliary: less than 10%; fecal: small amount.
Renal excretion 50-70% (amoxicillin) and 40-60% (clavulanate) as unchanged drug; tubular secretion and glomerular filtration. Fecal elimination <10%.
