Description

General description

Chemical structure: macrolide

Application

Rifampicin is used to treat Tuberculosis and Tuberculosis-related mycobacterial infections. It is widely used as an antipruritic agent in the autoimmune cholestatic liver disease, primary biliary cirrhosis (PBC). It has been shown to cause hepatitis.

Biochem/physiol Actions

Inhibits the assembly of DNA and protein into mature virus particles.

Mode of Action: Inhibits initiation of RNA synthesis by binding to β-subunit of RNA polymerase.

Rifampicin inhibits the assembly of DNA and protein into mature virus particles. It inhibits initiation of RNA synthesis by binding to β-subunit of RNA polymerase, which results in cell death.
