Test Details: Moxifloxacin is a fluoroquinolone that has potent in vitro activity against M. tuberculosis. It functions by inhibiting enzymes. Moxifloxacin moved into clinical development for use in TB through early-phase clinical trials where the drug was administered as monotherapy for a short period. It proved potent and was used along with other powerful antibiotics. Moxifloxacin should be taken during the intensive (6 month) and continuation (12-18 months) phases of treatment.
