Cefaclor is a second-generation cephalosporin that targets bacterial cell wall synthesis, making it effective against many beta-lactamase–producing respiratory pathogens.
Cefaclor is a semi-synthetic second-generation cephalosporin. It binds penicillin-binding proteins and interrupts the transpeptidation step of peptidoglycan synthesis, weakening the bacterial cell wall and triggering autolysis in dividing organisms.
