Mode of Action
Rifaximin is an antibacterial drug of the Rifamycin class that irreversibly binds the beta sub-unit of the bacterial enzyme DNA-dependent RNA polymerase and consequently inhibits bacterial RNA synthesis. Rifaximin has a broad antimicrobial spectrum against most of the Gram-positive and negative, aerobic and anaerobic bacteria, including ammonia producing species. Rifaximin may inhibit the division of Urea-Delaminating Bacteria, thereby reducing the production of Ammonia and other compounds that are believed to be important to the pathogenesis of Hepatic Encephalopathy.
