Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ampicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs); sulbactam is a beta-lactamase inhibitor that prevents degradation of ampicillin by beta-lactamases.
Amoxicillin is a semisynthetic penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
3 g (ampicillin 2 g + sulbactam 1 g) IV every 6 hours; total daily dose of sulbactam not to exceed 4 g.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours for 7-14 days; maximum 4 g/day.

Ampicillin: ~1 hour (normal renal function); sulbactam: ~1-1.4 hours (normal renal function); prolonged in renal impairment (ampicillin up to 20 hours, sulbactam up to 10-15 hours in anuria).
0.7-1.4 hours (mean ~1 hour) in adults with normal renal function; prolonged to 2-6 hours in anuria.
Renal: ampicillin (~75-90% unchanged) and sulbactam (~75-85% unchanged); biliary/fecal: minimal (<5% for each component).
Renal: 60-70% unchanged via glomerular filtration and tubular secretion; biliary: <5%; fecal: <5%.
