BEDAQUILINE
Background and Date of Approval
Bedaquiline is an antimycobacterial agent approved by the FDA in 2012 for treatment of multidrug-resistant tuberculosis (MDR-TB). A 2016 Phase 2 study evaluated the safety and efficacy of bedaquiline in patients with multidrug-resistant tuberculosis. The study demonstrated that bedaquiline combined with a background regimen led to improved treatment outcomes, establishing its role as a key component in the management of drug-resistant TB.
Uses
Bedaquiline is used as part of combination therapy to treat multidrug-resistant pulmonary tuberculosis in adults when other alternatives are not sufficient.
How is it administered?
Bedaquiline is administered orally, usually in combination with other TB medications. The dose and duration depend on the patient's condition and their response to treatment. It is essential to follow the prescribed regimen closely.
Side Effects
Common side effects include nausea, joint pain, headache, and dizziness. Serious effects like QT prolongation and liver toxicity can occur and need monitoring.
Warnings
Bedaquiline should not be used as monotherapy due to the risk of resistance. QT prolongation has been observed, and its use requires ECG monitoring.
Precautions
Bedaquiline should be used cautiously by patients with a history of heart conditions or those taking other drugs that affect heart rhythm.
Word of Advice
Bedaquiline should be taken with food to enhance absorption. Completing the entire course of therapy without missed doses is essential, as interruptions can result in treatment failure and resistance development. Alcohol should be avoided and liver function should be monitored throughout treatment.
