title: Cisapride or metoclopramide to accelerate small bowel transit during barium follow-through examination?
abstract: BACKGROUND
  Metoclopramide is commonly used to accelerate small bowel transit during barium follow-through (BaFT) examinations, but its action is unpredictable. Cisapride, commonly used to treat gastroesophageal reflux disease, also accelerates small bowel transit and may be a viable alternative. The two were compared in a prospective, randomized, blind study.
  
  
  METHODS
  Patients attending for BaFT were randomized to receive either 10 mg cisapride or 20 mg metoclopramide orally 1 h before the barium suspension. BaFT was performed by using a standard technique, and small bowel transit and study quality were compared. Patients also noted any side effects experienced.
  
  
  RESULTS
  Of 45 patients recruited, 27 received cisapride and 18 metoclopramide. Median transit time for the cisapride group was 30 min (range = 10-130 min) versus 67.5 min (range = 30-290 min) for the metoclopramide group (p = 0.019). Study quality was comparable. However, nine patients (33%) receiving cisapride experienced nausea versus only one subject (6%) receiving metoclopramide (p = 0.034).
  
  
  CONCLUSIONS
  This study suggests that cisapride is a more effective prokinetic agent than metoclopramide, but this benefit is offset by a higher incidence of side effects.
