Cefalexin is a broad-spectrum 1. generation cephalosporin antibiotic used to treat bacterial infections.

Essential insights

• Inhibition of cell wall synthesis: Cefalexin works by inhibiting the synthesis of bacterial cell walls. It binds to penicillin-binding proteins (PBPs) on the bacterial cell wall, interfering with the formation of peptidoglycan, which is a critical component of the cell wall.
• Bactericidal effect: By disrupting cell wall synthesis, Cefalexin causes the bacterial cell wall to weaken and eventually rupture, leading to bacterial cell death. This bactericidal effect helps eliminate the infection.
• Broad-spectrum activity: Cefalexin is effective against a broad range of Gram-positive and some Gram-negative bacteria, making it useful for treating various types of infections.
