Key takeaways
Viberzi (eluxadoline) and Motegrity (prucalopride) are both prescription medications used to treat digestive issues, but they work differently and treat different conditions. Viberzi is an antidiarrheal medication used to treat irritable bowel syndrome with diarrhea (IBS-D). It works by attaching to opioid receptors in the intestines to reduce abdominal pain and diarrhea. On the other hand, Motegrity is a serotonin-4 receptor agonist used to treat chronic idiopathic constipation (CIC) in adults. It stimulates the gut to move, helping to push food through the digestive tract. Viberzi is taken twice a day with food, while Motegrity is taken once a day, with or without food. Viberzi is a controlled substance due to its potential for abuse and dependence, whereas Motegrity is not a controlled medication. Common side effects of Viberzi include constipation, nausea, and abdominal pain, while Motegrity commonly causes headaches, stomach pain, and nausea. Additionally, Viberzi carries a risk of pancreatitis, especially in people without a gallbladder, whereas Motegrity has a warning for potential suicidal thoughts and behavior.
