Factors affecting short- and long-term outcome of a short therapeutic trial with cisapride in dyspeptic patients.

In a Dutch general practice trial conducted in 599 patients with symptoms of dyspepsia, the response to 5 mg cisapride three times daily was rated excellent or good in 61% of patients at week 2. On increasing the dose to 10 mg three times daily in 132 patients with poor to moderate response, the result at the end of treatment was rated as good or excellent in 45% of these patients, and the mean symptom score further decreased significantly (p < 0.05).
