WebBy using rifampicin to screen for rifabutin resistance in vitro, the authors sequenced the rpoB gene. All 54 resistant strains carried at least one mutation in the rpoB gene at codons 525, 530, 538, 540 in the rifampicin resistance determining region. A new mutation, L547, ... WebRifabutin achieves its peak concentrations after 3–4 h, and it has a large volume of distribution, with C max values only reaching 0.3–0.9µg/ml with 300 mg daily dosing. It also has a longer half-life than rifampicin (25 h). Rifabutin’s role is generally as a substitute for rifampicin in patients on protease
