About

This clinical study is being conducted to evaluate the investigational drug, Budesonide, for the treatment of functional dyspepsia. The goal of this study is to learn more about the effect of Budesonide on patients with functional dyspepsia. Budesonide is a well-known and commonly used drug, and is part of the recommended therapy for patients with inflammatory bowel diseases (Crohn's disease or ulcerative colitis). It is also used as inhalation therapy for respiratory conditions such as asthma and COPD. However, the effect of Budesonide in patients with functional dyspepsia is still unknown. In patients with functional dyspepsia, an increased presence of inflammatory cells has been observed in the duodenum. Budesonide may reduce inflammatory responses.

Therefore, with this study, the investigators aim to investigate primarily:

1. Whether Budesonide has an effect on the inflammatory cells observed in functional dyspepsia.
2. Whether the symptoms of patients with functional dyspepsia improve during and after taking Budesonide.
3. Whether inflammatory cells could be the cause of symptoms in functional dyspepsia.

Enrollment: 56 estimated patients

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
