How does it work?
Resolor tablets contain the active ingredient prucalopride, which is a type of medicine called a serotonin (or 5HT) agonist. It is used to treat constipation in women.
Prucalopride works by stimulating receptors called serotonin (or 5HT) receptors that are found on the walls of intestine. A natural substance called serotonin normally acts on these receptors, causing the muscles in the intestinal wall to contract. This process is known as peristalsis. It moves the contents of the intestines through the colon to the rectum so that the bowel can be emptied.
Prucalopride mimics this action of serotonin by directly stimulating specific serotonin receptors, known as 5HT4 receptors on the colon. This increases the muscular contraction of the colon, helping to produce normal bowel movement and relieve constipation.
What is it used for?
- Treatment of chronic constipation in women for whom other laxatives have not given adequate relief.
