Summary
Functional dyspepsia is a common gastrointestinal disorder. Symptoms can include stomach pain or discomfort, bloating, fullness after eating meals, and nausea. These symptoms often interfere with school and work, and weight loss may occur due to dietary restrictions. The hypothesis of this study was that antidepressant therapy is more effective than placebo in relief of the symptoms of functional dyspepsia, adjusting for psychological and psychiatric co-morbidity. The study also examined if antidepressant therapy reduces disability and improves quality of life in functional dyspepsia.Phase:

Criteria
Inclusion Criteria:- Normal esophagogastroduodenoscopy (EGD) (no esophagitis, Barrett's esophagus, cancer,
erosions, or ulcer disease) within the past 5 years
- Diagnosis of functional dyspepsia
- Patients may have failed to adequately respond to antisecretory therapy in the past
for functional dyspepsia to be suitable; a good response to antisecretory therapy,
which remains first line therapy, suggests underlying gastroesophageal reflux disease
(GERD).
Exclusion Criteria:
- Any documented history of endoscopic esophagitis, or predominant heartburn or acid
regurgitation, or these symptoms two or more times per week in the prior year, to
exclude GERD.
- Those who have had an adequate response to antisecretory therapy according to the
physician interview, to exclude patients with disease easy to control with first line
therapy or misdiagnosed GERD.
- Any documented peptic ulcer disease.
- Regular use of non-steroidal anti-inflammatory drugs (except long term low dose
aspirin ≤ 325 mg / day)
- Subjects undergoing psychiatric treatment, having a current history of drug or alcohol
abuse, or currently taking psychotropic medication for depression or psychosis, or
eating disorders
- A history of abdominal surgery except appendectomy, cholecystectomy or hysterectomy,
tubal ligations, bladder slings, and vasectomies
- Subjects with concurrent major physical illness (including cardiac or liver disease,
diabetes, inflammatory bowel disease, glaucoma, urinary retention, active thyroid
disease, vasculitis, lactose intolerance explaining symptoms)
- Subjects whose literacy skills are insufficient to complete self report
questionnaires.
- Pregnancy, or refusal to apply adequate contraceptive measures during the trial
- Subjects currently on antidepressant therapy will be excluded.
- Patients who score 11 or greater on the 7 questions related to depression of the
Hospital Anxiety Depression Scale will be excluded. These patients will be encouraged
to get follow up for depression.

to have significant arrhythmias, conduction defects or a previous myocardial
infarction on EKG will be excluded. Anyone with QT prolongation will be excluded.
The following concomitant medications will be prohibited during the trial:
- Systemically acting cholinergics and anticholinergics (atropine, didinium bromide,
propantheline)
- Prokinetics (e.g., metoclopramide, tegaserod)
- Macrolide antibiotics (e.g., erythromycin, azithromycin)
- Aspirin (> 325 mg/day)
- Spasmolytics (e.g., dicyclomine)
