About
Rifaximin is a non-systemic antibiotic that works primarily in the gastrointestinal tract, with minimal absorption into the bloodstream. It is effective against a broad spectrum of gut bacteria, including both gram-positive and gram-negative aerobes and anaerobes. Its localized action makes it particularly useful for treating conditions where bacterial overgrowth or specific bacterial pathogens in the gut contribute to symptoms. By reducing the bacterial load in the intestines, rifaximin helps to alleviate symptoms associated with various gastrointestinal disorders without causing widespread systemic antibiotic effects.
This antibiotic is commonly prescribed for conditions such as traveler's diarrhea, irritable bowel syndrome with diarrhea (IBS-D), and hepatic encephalopathy. In hepatic encephalopathy, it reduces ammonia-producing bacteria in the gut, thereby lowering ammonia levels in the blood and improving neurological function. Its unique mechanism of action and favorable safety profile make it a valuable therapeutic option for managing specific gut-related bacterial imbalances.
