Being a broad-spectrum antibiotic, it is a semisynthetic derivative of rifamycin SV. It irreversibly binds beta-subunits of bacterial enzyme, DNA-dependent RNA polymerase and thus inhibits the synthesis of RNA and proteins of bacteria. As a result of irreversible binding to the enzyme, rifaximin exhibits bactericidal properties against susceptible bacteria.
It has a wide spectrum of antibacterial activity, including most gram-negative and gram-positive, aerobic and anaerobic bacteria that cause gastrointestinal infections, including travelers' diarrhea.
Treatment of gastrointestinal infections caused by bacteria sensitive to rifaximin, including acute gastrointestinal infections; traveler's diarrhea; syndrome of excessive growth of microorganisms in the intestines; hepatic encephalopathy; symptomatic uncomplicated diverticulosis of the colon; chronic inflammation of the intestine.
Prevention of infectious complications during colorectal surgery.
Increased sensitivity to rifaximin and other antibiotics of the rifamycin group.
In case of long-term treatment with high doses of rifaximin or damage to the intestinal mucosa, small amounts of the active agents may be absorbed into the systemic circulation and cause reddish urine color due to the reddish-orange color of antibiotics of rifamycin group.
