Also known as LM-427, Ansamicin, 4-N-Isobutylspiropiperidylrifamycin S, Mycobutin (tn), 1,4-Dihydro-1-deoxy-1',4-didehydro-5'-(2-methylpropyl)-1-oxorifamycin xiv, Ansamycin, 4-Deoxo-3,4-(2-spiro(N-isobutyl-4-piperidyl)-2,5-dihydro-1H-imidazo)-rifamycin S, Mycobutin

Rifabutin (Rfb) is an antibiotic used to treat tuberculosis and prevent and treat Mycobacterium avium complex. It is typically only used in those who cannot tolerate rifampin such as people with HIV/AIDS on antiretrovirals. For active tuberculosis it is used with other antimycobacterial medications. For latent tuberculosis it may be used by itself when the exposure was with drug-resistant TB.
