The active antibacterial ingredient in Rifadin® is Rifampicin. It comes in three forms:

  • Capsules

Rifampicin® inhibits the activity of the enzyme DNA-dependent RNA polymerase in infected cells, hence inhibiting their growth and reproduction while healthy mammalian cells remain unaffected and protected.

  • Mycobacterium tuberculosis
