"New WHO recommendations aim to speed up detection and improve treatment outcomes for multidrug resistant tuberculosis (MDR-TB) through use of a novel rapid diagnostic test and a shorter, cheaper treatment regimen.
INCREASED MORTALITY; QT PROLONGATION
- An increased risk of death was seen in the SIRTURO treatment group (9/79, 11.4%) compared to the placebo treatment group (2/81, 2.5%) in one placebo-controlled trial. Only use SIRTURO when an effective treatment regimen cannot otherwise be provided [see INDICATIONS AND USAGE and WARNINGS AND PRECAUTIONS].
- QT prolongation can occur with SIRTURO. Use with drugs that prolong the QT interval may cause additive QT prolongation. Monitor ECGs. Discontinue SIRTURO if significant ventricular arrhythmia or if QTcF interval prolongation of greater than 500 ms develops [see WARNINGS AND PRECAUTIONS].
SIRTURO (bedaquiline) for oral administration is available as 100 mg strength tablets. Each tablet contains 120.89 mg of bedaquiline fumarate drug substance, which is equivalent to 100 mg of bedaquiline. Bedaquiline is a diarylquinoline antimycobacterial drug.
Bedaquiline fumarate is a white to almost white powder and is practically insoluble in aqueous media. The chemical name of bedaquiline fumarate is (1R, 2S)-1-(6-bromo-2methoxy-3-quinolinyl)-4-(dimethylamino)-2-(1-naphthalenyl)-1-phenyl-2-butanol compound with fumaric acid (1:1). It has a molecular formula of C32H31BrN2O2•C4H4O4 and a molecular weight of 671.58 (555.50 + 116.07). The molecular structure of bedaquiline fumarate is the following:
SIRTURO (bedaquiline) contains the following inactive ingredients: colloidal silicon dioxide, corn starch, croscarmellose sodium, hypromellose 2910 15 mPa.s, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polysorbate 20, purified water (removed during processing).
