Cephalexin Mechanism Of Action

Cephalexin, such as penicillin, is a beta-lactam antibiotic. By binding to specific binding proteins, penicillin (PBP) located in the bacterial cell wall inhibits the third and final phase of the synthesis of bacterial cell walls. Lysa cells are then mediated by autolytic bacterial cell wall enzymes such as autolysins; it is possible that cefalexin interferes with the autolysin inhibitor.
