Rifaximin is an antibiotic derived from rifamycin SV (Item No. 21441) that inhibits the growth of a variety of Gram-positive and Gram-negative bacteria in vitro, including Staphylococcus, Streptococcus, Enterococcus, H. influenzae, and N. gonorrhoeae (MIC50s = ≤0.015, 50 = ~20 μM) that reduces colonic damage, rectal bleeding, and diarrhea in PXR-humanized, but not wild-type or Pxr-null, mice with inflammatory bowel disease (IBD) induced by dextran sulfate sodium (DSS; Item No. 23250).{42471,42472} Rifaximin exhibits minimal intestinal absorption after oral administration and is, therefore, effective in eliminating bacteria in the gastrointestinal system.{26322,26320} Formulations containing rifaximin have been used in the treatment travelers’ diarrhea caused by noninvasive E. coli, irritable bowel syndrome with diarrhea (IBS-D), and to reduce the risk of recurrence of overt hepatic encephalopathy.
