Mechanism of action

Beta-lactams contain a four-membered beta-lactam ring that irreversibly inhibits transpeptidase enzymes responsible for cross-linking peptidoglycan strands in the bacterial cell wall. This disruption weakens the cell wall, leading to bacterial cell lysis and death. The class includes penicillins, cephalosporins, carbapenems, and beta-lactamase inhibitor combinations.
