Bedaquiline Fumarate

**Semantic type:** Pharmacologic Substance

**Definition:** The fumarate salt form of bedaquiline, an orally bioavailable diarylquinoline antimycobacterial agent, that can be used in the treatment of pulmonary multi-drug resistant tuberculosis (MDR-TB). Upon oral administration, bedaquiline specifically binds to subunit c of Mycobacterium tuberculosis (M. tuberculosis) adenosine 5'-triphosphate (ATP) synthase, thereby preventing ATP synthase activity. This inhibits ATP synthesis in M. tuberculosis, thereby blocking its energy metabolism and killing M. tuberculosis.
