FAQ

Why is rifaximin used in IBS?

The findings indicate that people with IBS have an overabundance of bacteria in the small bowel, a condition known as bacterial overgrowth. As a result, antibiotic-based therapies for IBS may be beneficial. Rifaximin is a nonabsorbable antibiotic with no clinically significant bacterial resistance.

Is rifaximin an anti-inflammatory?

The medicine possesses anti-inflammatory qualities that help to stabilize the gut mucosa, which is vital for its long-term benefits in non-infectious disorders. Rifaximin is used to treat hepatic encephalopathy and diarrhea-predominant irritable bowel syndrome on a long-term or recurring basis.

What is the mechanism of action of rifaximin?

Rifaximin inhibits RNA synthesis in sensitive bacteria by attaching to the beta subunit of the bacterial DNA-dependent ribonucleic acid (RNA) polymerase enzyme. Its binding prevents translocation and hence transcription.
