CROI 2013: Researchers Discuss Advances in Tuberculosis Treatment

A new two-drug combination of rifapentine and moxifloxacin can allow tuberculosis (TB) treatment to be taken just once-weekly during the 4-month continuation phase, according to a presentation at the 20th Conference on Retroviruses and Opportunistic Infections (CROI 2013) last week in Atlanta. A related meta-analysis found that rifampicin, a key drug in TB treatment, can be tolerated at much higher levels than used in current clinical practice, suggesting that higher doses might allow the treatment course to be shortened.
