Rifampicin inactivates bacterial RNA polymerase (RNAP) at about 0.01-02 μg/mL (50% effective dose). Rifampicin has activity against a wide range of microorganisms such as mycobacteria including Mycobacterium tuberculosis9 and M. leprae.12 Rifampicin is highly active against Gram-positive bacteria, such as staphylococci, streptococci, pneumococci but is less active against Gram-negative organisms. Rifampicin inhibits initiation of RNA synthesis by binding to b-subunit of RNA polymerase.
