Cefalexin
Nature of the antibiotic Mechanism of action Cefalexin, like other beta-lactams, binds to the penicillin-binding protein (PBP) and prevents peptidoglycan synthesis. It prevents the formation of new cell walls and maintenance of the cell wall leading to autolysis of the bacteria due to osmotic pressure. Mechanism of resistance PK/PD and other properties Indication (cefalexin is […]
