Rifabutin taken at a dose of 300 mg once-daily might be as effective for tuberculosis treatment as rifampin.

Expert commentary: Rifampin has shorter half-life, higher MIC against M. tb, lower protein binding, and better distribution into cavitary contents than rifapentine. Drug interactions for the two drugs maybe similar in magnitude. For LTBI, rifapentine is effective as convenient, once-weekly, 12-week course of treatment.
