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.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting peptidoglycan cross-linking.
250-500 mg orally every 8 hours or 500 mg every 12 hours; for severe infections, up to 1 g every 6 hours intravenously.
500 mg IV every 6 hours or 1 g IV every 8 hours for moderate infections; 2 g IV every 4 hours for severe infections.
