RIFNIM 550 TABLET

🧫💊 Rifaximin 550mg Tablet: Targeted Relief for Gut-Related Infections

Rifaximin 550mg is a broad-spectrum, non-absorbable antibiotic primarily used to treat gastrointestinal (GI) infections. Its unique property lies in its minimal systemic absorption, meaning it works almost entirely within the gut, reducing the risk of systemic side effects. Rifaximin is especially effective in managing hepatic encephalopathy, irritable bowel syndrome with diarrhea (IBS-D), and traveler’s diarrhea caused by Escherichia coli.

🧪 Mechanism of Action

Rifaximin works by binding to the bacterial DNA-dependent RNA polymerase, thereby inhibiting bacterial RNA synthesis and protein production. This results in the elimination or suppression of harmful bacteria in the gastrointestinal tract. Its bactericidal activity is largely confined to the intestines due to its poor absorption, making it safe for long-term gut-targeted use.

📋 Indications and Uses

Rifaximin 550mg is prescribed for:

1. Hepatic Encephalopathy (HE)

   • Used to prevent recurrence of HE episodes in patients with chronic liver disease.

   • It reduces the production of ammonia by altering the gut flora.

2. Irritable Bowel Syndrome with Diarrhea (IBS-D)

   • Helps in reducing bloating, abdominal pain, and loose stools by modulating gut bacteria.

3. Small Intestinal Bacterial Overgrowth (SIBO) (off-label use)

   • Effective in treating bacterial overgrowth in the small intestine, leading to better digestion and less bloating.

4. Traveler’s Diarrhea

   • Used to treat mild to moderate diarrhea caused by non-invasive E. coli in adults.

5. Crohn’s Disease and Ulcerative Colitis (investigational use)

   • Being explored as adjunctive therapy in inflammatory bowel disease.
