What this trial studies

This clinical trial aims to evaluate the effectiveness of trimebutine and probiotics in alleviating Functional Abdominal Pain Disorders (FAPD) in children aged 4 to 18. Participants will be randomly assigned to one of three groups: trimebutine/probiotics, probiotics/placebo, or trimebutine/placebo. The study will measure pain levels and quality of life at the start, after 4 weeks, and after 8 weeks of treatment. The trial follows a double-blind, placebo-controlled design to ensure unbiased results.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged 4 to 18 who meet the Rome IV criteria for Functional Abdominal Pain Disorders.

Not a fit: Patients with abdominal pain of organic cause or those who are immunosuppressed will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide effective treatment options for children suffering from functional abdominal pain.

How similar studies have performed: Other studies have shown promise in using probiotics for gastrointestinal disorders, but the combination with trimebutine in this context is relatively novel.
