How Linezolid Works

Linezolid belongs to the oxazolidinone class of antibiotics. It works by inhibiting bacterial protein synthesis, which is essential for bacteria to grow and multiply.

This action helps to stop the spread of infection and allows the body’s immune system to eliminate the bacteria.

By targeting the bacteria’s ability to produce proteins, Linezolid effectively reduces the infection.
