Rifamycin (sodium)

Rifamycin sodium (Rifamycin SV monosodium) is an orally active ansamycin antibiotic. Rifamycin sodium inhibits DNA-dependent RNA synthesis. Rifamycin sodium has antibacterial activity against Mycobacterium tuberculosis. Rifamycin sodium interferes with hepatic bile acid metabolism. Rifamycin sodium has anti-inflammatory effects. Rifamycin sodium can be used in the study of Mycobacterium tuberculosis, Bacteroides fragilis infection, and Lipopolysaccharide -induced inflammation[1][2][3][4][5][6][7][8][9][10][11].
