Rifampicin suppresses initiation of chain formation for RNA synthesis in susceptible bacteria by binding to the beta subunit of DNA-dependent RNA polymerase, thus blocking RNA transcription.
Drug Interactions ::
May accelerate the metabolism and reduce the effect of drugs that are metabolised by CYP450 enzymes (e.g. quinidine, phenytoin, theophylline). Decreased concentrations of atovaquone and increased concentrations of rifampicin when taken concomitantly. Concurrent use of ketoconazole and rifampicin may result in decreased serum concentrations of both drugs. May decrease serum concentrations of enalaprilat. Reduced absorption by antacids. Increased risk of hepatotoxicity w/ halothane or isoniazid. Potentially Fatal: Increased potential for hepatotoxicity when taken concomitantly w/ saquinavir/ritonavir combination.
