what is viberzi
Viberzi (eluxadoline) is a novel drug approved for treating irritable bowel syndrome with diarrhea (IBS-D). Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder that causes abdominal pain or discomfort and bowel movement changes. The exact mechanism of action of Viberzi is not known. Viberzi activates mu-opioid receptors, blocks delta-opioid receptors, and activates kappa-opioid receptors in the gastrointestinal tract (GIT). Activating mu-opioid receptors reduces pain and slows gut movement, reducing abdominal pain and diarrhea.
