SponsorJuan A. Arnaiz
Drug classBeta-lactam antibiotic combination
TargetBacterial cell wall synthesis (MurA enzyme and penicillin-binding proteins)
ModalitySmall molecule

Mechanism of action

Fosfomycin inhibits MurA enzyme in peptidoglycan synthesis, while imipenem is a broad-spectrum beta-lactam that inhibits penicillin-binding proteins. This combination provides synergistic coverage against multidrug-resistant gram-negative and gram-positive bacteria, including some carbapenem-resistant organisms. The dual mechanism reduces the likelihood of resistance development.
