About Rifamycins.

Rifamycins are a class of ansamycin antibacterial agents that include drugs such as rifampin, rifabutin, rifapentine, and rifaximin.

They exert bactericidal activity by selectively binding to the beta subunit of bacterial DNA-dependent RNA polymerase, thereby blocking RNA synthesis and gene transcription.

Clinically, rifamycins serve as cornerstone therapies for mycobacterial infections, notably active and latent tuberculosis, as well as leprosy and *Mycobacterium avium* complex.

Minimally absorbed oral derivatives are also utilized to treat gastrointestinal conditions, including travelers’ diarrhea, irritable bowel syndrome, and hepatic encephalopathy.
