title: The effect of cisapride on dyspepsia symptoms and the electrogastrogram in patients with non-ulcer dyspepsia.
abstract: BACKGROUND
  The electrogastrogram (EGG), which records gastric myoelectrical activity, is abnormal in one-third of adult patients with non-ulcer dyspepsia (NUD).
  
  
  OBJECTIVE
  To observe the effects of cisapride on EGG in adults with NUD.
  
  
  METHODS
  Twenty-seven NUD patients who had undergone a pre- and post-prandial EGG were entered into an open study. All patients completed a dyspepsia symptom questionnaire and were then treated with cisapride 10 mg t.d.s. The dyspepsia questionnaire was repeated in all those completing 4 weeks of treatment. Those with an initial abnormal EGG (< 70% of slow wave activity at 2-4 cycles per minute) had a repeat EGG at the end of the study.
  
  
  RESULTS
  Treatment with cisapride was associated with a significant improvement in the post-prandial EGG (P = 0.007). After 4 weeks of treatment, 7 of 13 abnormal EGGs normalized. Symptom scores improved significantly in the 13 patients with an abnormal EGG who completed treatment (P < 0.0003), but not in NUD patients with a normal EGG (P = 0.48).
  
  
  CONCLUSIONS
  In this open study, treatment of NUD with cisapride was associated with significant symptom improvement in patients with an abnormal pre-treatment EGG, but not those with a normal EGG, with a significant improvement of the post-prandial EGG.
