概览

Prucalopride is a 5-HT4 receptor agonist indicated to treat adults with chronic idiopathic constipation.

作用机制

Prucalopride acts as a selective stimulator of the 5-HT4 receptors while having no interaction with hERG channel or 5-HT1 receptors which reduces significantly the cardiovascular risk found in other similar drugs. 5-HT4 receptors can be found throughout the gastrointestinal tract primarily in smooth muscle cells, enterochromaffin cells, and myenteric plexus. Its activation produces the release of acetylcholine which is the major excitatory neurotransmitter in the GI tract. Hence, prucalopride stimulates motility by interacting specifically with 5-HT4 receptors in the GI tract which causes a release of acetylcholine and further contraction of the muscle layer of the colon and relaxation of the circular muscle layer leading to the propulsion of luminal content.

适应症

Prucalopride is indicated for the treatment of chronic idiopathic constipation (CIC) in adults. CIC is one of the most common chronic functional gastrointestinal disorders worldwide. The diagnosis of this agent is very hard and it can be confirmed if the patient experience at least two of the following: -Straining during more than 25% of the bowel movements. -Lumpy or hard stools in 25% of the bowel movements. -Sensation of incomplete evacuation in more than 25% of all bowel movements. -Sensation of anorectal blockage or obstruction in more than 25% of the bowel movements. -Manual maneuvers required in more than 25% of the bowel movements. -Fewer than 3 bowel movements per week.
