How Linezolid works

By blocking protein production, the bacteria cannot grow, reproduce, or repair themselves, which eventually kills them. Unlike many other antibiotics, Linezolid is especially effective against Gram-positive bacteria, including resistant strains like MRSA (methicillin-resistant Staphylococcus aureus) and VRE (vancomycin-resistant Enterococcus).
