Primary Outcome Measures:
  • Question on Whether Patient Has Had Adequate Relief of Abdominal Pain or Discomfort Reported by a Simple Yes or no Answer. [ Time Frame: 8 weeks ]
    Patient would answer yes or no to a simple question asking whether they had adequate relief of abdominal pain or discomfort. This was measured at weeks 2,4 and 8 of the study but only week 8 was reported. What is being reported is the number of participants who answered yes.

Secondary Outcome Measures:
  • QOLRAD Questionaire for Patients With Upper Abdominal Symptoms [ Time Frame: 8 weeks ]
    Patients were administered the validated QOLRAD questionnaire on quality of life to assess if nortriptyline improves quality of life in patients with nonulcer dyspepsia

  • Side Effects [ Time Frame: 8 weeks ]
    To assess frequency of side effects in patients receiving Nortriptyline for nonulcer dyspepsia. Patients were asked about side effects on each office visit and ask to call for significant side effects.

Detailed Description:

Nonulcer dyspepsia is a common complaint in clinical practice and its management should be based on the best evidence. Many clinical trials of nonulcer dyspepsia suffer from important weaknesses in trial design. This makes it difficult to determine whether truly efficacious therapies exist for this disorder.

Once a diagnosis of nonulcer dyspepsia is confirmed by normal endoscopy, a trial of therapy is commonly prescribed. However, the benefits of all therapies in this condition have been questioned. Small studies have suggested benefit in use of antidepressants such as Nortriptyline and even though the data is insufficient, antidepressants such as Nortriptyline are widely used in clinical practice largely due to lack of proven, reliable therapies for nonulcer dyspepsia.

Our hypothesis is that Nortriptyline will improve symptoms of nonulcer dyspepsia and improve quality of life.
