What can Motegrity be taken for?

It is a prescription medicine given to adults for the treatment of chronic idiopathic constipation (CIC) and for the treatment of irritable bowel syndrome with constipation (IBS-C). Chronic idiopathic constipation can be treated by making lifestyle changes, like eating more dietary fiber, increasing your water intake, and taking regular physical exercise. But often this may prove insufficient, particularly with stubborn cases. If you have chronic idiopathic constipation, your doctor may have prescribed Motegrity to you.

The active ingredient in Motegrity is called prucalopride. It’s a type of drug called a serotonin receptor agonist that can speed up how quickly food moves through your digestive system, also known as motility. Muscles in your bowels rhythmically contract (tighten) and relax, to move food through your bowels. This process is called peristalsis, and if it happens too slowly, it can cause constipation as the food in your bowels hardens over time. Motegrity can help to stop this from happening. Motegrity stimulates colonic peristalsis and bowel motility by causing acetylcholine release in gastrointestinal neurons.

When you take Motegrity, the active ingredient prucalopride is released into your bowels. It attaches to areas on the outside of the cells in your bowels called 5-HT4 serotonin receptors. This stimulates the receptors, making them produce a natural substance called acetylcholine. The acetylcholine makes your bowel muscle contract faster, speeding up peristalsis and motility.
