How does Trulance work?

Trulance is an analog of uroguanylin, a substance that is naturally found in the body and plays a role in the amount of fluid in the intestines. Too little fluid in the digestive system can lead to hard stools and constipation, while too much fluid can lead to diarrhea. Trulance acts as a guanylate cyclase-C (GC-C) agonist which ultimately increases the amount of fluid in the intestines, accelerates the intestinal transit (the movement of food through the digestive tract), and reduces constipation.1,2

What are the possible side effects of Trulance?

In clinical trials, the most common side effect experienced by people taking Trulance was diarrhea. Diarrhea can sometimes be severe, and if it occurs as a result of treatment with Trulance, it most likely occurs within the first 4 weeks of treatment. People who experience diarrhea while they are taking Trulance should stop taking Trulance and contact their doctor.1,2 This is not an exhustive list of side effects so patients should consult their doctor if they experience anything unusual while taking Trulance.
