Additional Details

Bedaquiline is indicated as part of combination therapy in adults (≥ 18 years) with pulmonary multi-drug resistant tuberculosis (MDR-TB).
Bedaquiline is primarily subjected to oxidative metabolism leading to the formation of N-monodesmethyl metabolite (M2). M2 is not thought to contribute significantly to clinical efficacy given its lower average exposure (23% to 31%) in humans and lower antimycobacterial activity (4 to 6-fold lower) compared to the parent compound. M2 concentrations appeared to correlate with QT prolongation. Bedaquiline inhibits mycobacterial TB at a minimal inhibitory concentration (MIC) from 0.002-0.06 μg/ml and with a MIC50 of 0.03 μg/ml. Furthermore, bacteria that have smaller ATP stores (usually in dormant, nonreplicating bacilli) are more susceptible to bedaquiline.
Mode of Action:
Bedaquiline is a diarylquinoline antimycobacterial drug that inhibits the proton pump of mycobacterial ATP (adenosine 5'-triphosphate) synthase, an enzyme that is essential for the generation of energy in Mycobacterium tuberculosis. Bacterial death occurs as a result of bedaquiline.
Bedaquiline is hepatically metabolized. The main enzyme involved is CYP3A4 which metabolizes bedaquiline into the N-monodesmethyl metabolite (M2). This metabolite is 4 to 6-times less active in terms of antimycobacterial potency.
The most common adverse reactions reported in ≥10% of patients treated with bedaquiline are nausea, arthralgia, and headache.
