HEPABACT 550 Tablets

Gastrointestinal infections and liver-related complications can significantly impact quality of life. Managing intestinal bacterial imbalance effectively is essential for long-term health. HEPABACT-550 Tablets, containing Rifaximin 550 mg, is a gut-selective antibiotic widely prescribed for hepatic encephalopathy and certain intestinal bacterial conditions.

What is Rifaximin 550 mg?

Rifaximin 550 mg is a minimally absorbed antibiotic that works locally in the gastrointestinal tract. Unlike systemic antibiotics, it primarily stays in the intestine, targeting harmful bacteria without significant absorption into the bloodstream.

HEPABACT-550 Tablets are commonly prescribed to manage conditions linked to excessive or harmful gut bacteria.

Rifaximin 550 mg Uses

HEPABACT-550 Tablets are indicated for:

  • Hepatic encephalopathy (reducing recurrence episodes)
  • Irritable bowel syndrome with diarrhea (IBS-D)
  • Traveler’s diarrhea caused by non-invasive strains of bacteria
  • Small intestinal bacterial overgrowth (SIBO)
  • Intestinal bacterial infections (as prescribed)

Mechanism of Action (MOA) of Rifaximin

Rifaximin works by inhibiting bacterial RNA synthesis. It binds to the beta-subunit of bacterial DNA-dependent RNA polymerase, preventing bacterial growth and replication.

Because Rifaximin is minimally absorbed from the gastrointestinal tract, it acts locally in the intestine. In hepatic encephalopathy, it helps reduce ammonia-producing gut bacteria, lowering blood ammonia levels and decreasing the risk of neurological complications.

Its localized action contributes to better tolerability and reduced systemic side effects.
