I did end up finding information on something that might be slightly more useful for TB patients. Researchers at the University of Colorado (as well as University of North Carolina, and Harvard University) have developed a way to inhale antibiotics that fight MDR TB, delivering the antibiotic straight to the deep lung tissue where TB first arises. They have even experimented with aerosols that could deliver this drug through something that is similar to an inhaler used by asthma patients. The hope here is that it would cut down dramatically on cost and treatment time for TB patients, as well as less severe side effects. More information can be found here:
