Study Stopped
The inclusion of participants went more difficult than initially thought. Preliminary analysis showed that the difference between the groups was great enough to draw conclusions from it, so the trial is terminated prematurely.

Brief Summary
Functional dyspepsia (FD) is a common functional gastrointestinal disorder characterized by upper abdominal discomfort/pain and/or symptoms of meal-related fullness/satiety. There is currently no definitive therapy that is beneficial for all FD patients. Accumulating evidence suggests efficacy of tricyclic antidepressants (TCAs) in FD. However, no firm conclusion can be drawn currently due to the relatively small amount of studies and large heterogeneity between studies. In addition, TCAs are often associated with side effects, which occur early after initiation of therapy preceding the therapeutic effect and often result in discontinuation of the therapy. These side effects are related to drug metabolism, which depend on polymorphisms of the cytochrome P (CYP) enzyme system. It is therefore hypothesized that pre-treatment assessment of CYP genotype and subsequent exclusion of abnormal metabolizers limits the occurrence of side-effects and as such improves compliance and efficacy.

Outcome Measures
Primary Outcomes (1)
Symptom response
Response to therapy, as defined by a 30% reduction from baseline (i.e. the run-in period) in the weekly average of daily symptom scores, during at least 50% of weeks 3-12 of treatment. Symptoms will be assessed daily using a digital diary (mobile phone application). Recorded symptoms include the five core symptoms of FD: epigastric pain, epigastric burning, postprandial fullness, early satiety and upper abdominal bloating.
