Rifaximin

Rifaximin is a broad-spectrum, non-absorbable antibiotic active pharmaceutical ingredient widely used for the treatment of gastrointestinal infections, including traveler’s diarrhea, hepatic encephalopathy, and irritable bowel syndrome with diarrhea (IBS-D). By inhibiting bacterial RNA synthesis, Rifaximin reduces pathogenic bacterial load in the gut while maintaining minimal systemic absorption, providing targeted therapy with a favorable safety profile. Pharmaceutical companies formulate Rifaximin into oral tablets and granules for suspension, ensuring convenient and precise dosing for adult and pediatric patients.

• Traveler’s Diarrhea – Reduces severity and duration of acute bacterial diarrhea.
• Hepatic Encephalopathy – Decreases ammonia-producing gut bacteria to prevent encephalopathy episodes.
• Irritable Bowel Syndrome with Diarrhea (IBS-D) – Helps manage gastrointestinal symptoms and improve quality of life.
• Gastrointestinal Infection Management – Targets localized bacterial overgrowth and infections in the intestine.
