Multidrug Resistant TB (MDR-TB)

This is a dangerous form of TB where the germs have got resistant to the standard drugs. India has the highest MDR-TB rates in the world and Bombay in particular is the epicenter of the MDR-TB epidemic.

This form of TB can only be diagnosed after the culture and sensitivity reports are received from a reliable microbiology laboratory.

It is a difficult form of TB to treat as the drugs needed to cure it have side effects and the duration of treatment is as high as 18 to 24 months. Some of the 2nd line drugs used include: injectable kanamycin, moxifloxacin, PAS, ethionamide, cycloserine, and clofazine.

Newer drugs and new diagnostic tests are emerging.
