Rifaximin is a semi-synthetic rifamycin antibiotic with a broad spectrum of activity against Gram-positive and Gram-negative bacteria, including aerobes and anaerobes. It is derived from rifamycin SV through chemical modification and is manufactured under cGMP conditions, meeting EP and USP standards. The product is supplied as a high-purity powder with an assay of ≥98.0% (HPLC), making it suitable for pharmaceutical formulation and research use.
Due to its minimal systemic absorption, rifaximin is primarily used in gastrointestinal indications such as travelers’ diarrhea, hepatic encephalopathy, and irritable bowel syndrome with diarrhea. Its low oral bioavailability and excellent safety profile have driven steady global demand, particularly in the United States, Europe, and Asia. As a key API, rifaximin is also employed in combination therapies and specialty formulations, where consistent quality and regulatory compliance are critical.
