How Does Bedaquiline Work?

Bedaquiline works by blocking an enzyme known as adenosine-5'-triphosphate (ATP) synthase. This enzyme is essential for creating energy that Mycobacterium tuberculosis (the bacteria that causes TB) needs to survive. By blocking this enzyme, bedaquiline prevents the bacteria from getting the energy it needs to survive and replicate.
