Despite U.S. approval of bedaquiline drug Sirturo for treating multidrug-resistant tuberculosis, it faces potential delays in India, where the health minister says other research facilities are testing new TB treatments using bedaquiline. Experts are concerned that a culture of misuse that has rendered other drugs increasingly ineffective could do the same for bedaquiline in a country that, along with China, Russia and South Africa, represents 60% of MDR-TB cases in the world. "My biggest concern is you're introducing a brand new TB drug into one of the most unregulated chaotic drug markets you can see anywhere in the world," said Madhukar Pai, founder of the Pai Tuberculosis Research Group at Montreal's McGill University.
