Clinical Question

In adults with newly diagnosed pulmonary tuberculosis, can the substitution of moxifloxacin for either isoniazid or ethambutol in a shortened four-month treatment regimen, compared to the standard six-month regimen, treat tuberculosis effectively?

Bottom Line

Four-month tuberculosis regimens containing moxifloxacin are not as effective as the standard six-month regimen.
