How Cephalexin Works to Treat Bacterial Infections

Sofialewis10 Jan, 2025Health

Cephalexin treats bacterial infections by inhibiting bacterial cell wall synthesis. It belongs to the cephalosporin class of antibiotics and is effective primarily against gram-positive bacteria like Streptococcus and Staphylococcus species. Cephalexin binds to penicillin-binding proteins within the bacterial cell wall, preventing the final stages of peptidoglycan synthesis, which is crucial for cell wall strength and rigidity.
