What this trial studies

This clinical study evaluates the effects of Budesonide, a medication commonly used for inflammatory bowel diseases, on patients suffering from functional dyspepsia. The study aims to determine whether Budesonide can reduce the inflammatory cells present in the duodenum and alleviate the symptoms associated with this condition. Participants will be monitored for changes in their symptoms and inflammatory responses over the course of the trial. The study includes patients aged 18 to 70 who meet specific diagnostic criteria for functional dyspepsia.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 70 diagnosed with functional dyspepsia, specifically postprandial distress syndrome, who have had a negative endoscopy within the last 12 months.

Not a fit: Patients with functional dyspepsia who do not meet the inclusion criteria or have other gastrointestinal conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide significant relief for patients suffering from functional dyspepsia by reducing inflammation and improving symptoms.

How similar studies have performed: While Budesonide is well-established for other conditions, its application for functional dyspepsia is novel and has not been extensively tested in previous studies.

Eligibility criteria

Inclusion Criteria:

1. Patients with Functional dyspepsia (subtype postprandial distress syndrome) as per Rome IV diagnostic criteria

5. Patients with eosinophilic esophagitis or eosinophilic gastroenteritis
6. Active H. Pylori infection (or \< 6 months after eradication)
7. Organic gastro-intestinal disease of history of gastrointestinal surgery other than appendectomy
8. Known impaired liver dysfunction
9. Drugs altering gastric emptying, anti-inflammatory drugs, acid suppressive drugs or some drugs altering the CYP3A4 metabolism
