Abstract：
:The comparative enzyme inducing effects of rifabutin and the chemically related drug rifampicin have been investigated in 8 normal subjects. Rifampicin 600 mg daily for 7 days caused considerable shortening of the antipyrine half-life and a marked increase in antipyrine clearance, associated with an increased rate of conversion to norantipyrine and, to a lesser extent, 4-hydroxyantipyrine and 3-hydroxymethylantipyrine. The urinary excretion of 6-beta-hydroxycortisol was also markedly increased, while plasma GGT activity showed only a slight albeit statistically significant elevation. In the same subjects, rifabutin in the proposed therapeutic dosage (300 mg daily) for 7 days also enhanced the metabolic elimination of antipyrine, with preferential stimulation of the demethylation pathway, and increased the excretion of 6-beta-hydroxycortisol, but the magnitude of the effects was significantly less than after rifampicin. No significant change in plasma GGT was seen. The results indicate that, contrary to the findings in animals, rifabutin does have enzyme inducing properties in man, although at the dosages assessed they were considerably less than those of rifampicin.
