Role of Prucalopride in Treating Functional Constipation and Gastroparesis: A Systemic Review

Prucalopride is a selective serotonin receptor agonist that can be used to treat chronic constipation. This article reviews the clinical efficacy side effects of prucalopride, assessing its role in constipation and gastroparesis. Relevant published medical literature was identified by using the search terms "constipation," "gastroparesis," and "prucalopride" from 2010 and onwards. The databases included PubMed/MEDLINE and EMBASE. Bibliographies from published literature and websites were also reviewed. Results were filtered for English language and randomized controlled trials. Out of the 18 results, abstracts were manually reviewed for studies with similar statistical methodology; eight studies were selected for constipation and two studies for gastroparesis. In two four-week trials, prucalopride showed improvement in gastric emptying and the gastroparesis cardinal symptom index over placebo, with a 1-4 mg/day dosage. In seven 12-week trials in patients with chronic constipation, oral prucalopride 2-4 mg/day was more significant than placebo to improve the number of bowel movements and symptoms. One study showed no significant bowel function differences when prucalopride was compared to placebo over 12 or 24 weeks. Prucalopride was generally well-tolerated, and the most common adverse events reported were headache, nausea, diarrhea, and abdominal pain. Further long-term and comparative data would be beneficial to show that prucalopride can be an advantageous treatment option for patients with chronic idiopathic constipation (CIC) or gastroparesis. Additionally, it would be interesting to see its effect on irritable bowel syndromeconstipation predominant, as it has some overlap with idiopathic constipation.
