Prucalopride: safety, efficacy and potential applications

Area of Science:

• Gastroenterology
• Pharmacology

Background:

• Chronic constipation is a prevalent functional gastrointestinal disorder impacting quality of life.
• Current treatments, including laxatives, often lack efficacy and patient satisfaction.
• There is a need for improved pharmacological interventions for chronic constipation.

Purpose of the Study:

• To evaluate the efficacy and safety of prucalopride, a selective serotonin 5-HT4 receptor agonist, for chronic constipation.
• To assess the long-term effects of prucalopride treatment.

Main Methods:

• Three large, pivotal randomized controlled trials were conducted.
• Patients received prucalopride for chronic constipation.
• Open-label follow-up was utilized to assess long-term outcomes.

Main Results:

• Prucalopride demonstrated effectiveness in relieving cardinal symptoms of chronic constipation.
• Sustained symptom relief was observed for up to 18 months in open-label follow-up.
• The drug exhibited an encouraging safety profile, notably lacking arrhythmogenic potential.

Conclusions:

• Prucalopride is an effective and well-tolerated treatment for chronic constipation.
• Its selectivity for the serotonin 5-HT4 receptor contributes to its prokinetic effects.
• Further studies in specific populations and conditions are warranted.
