Oral domperidone in chronic postprandial dyspepsia. A double-blind placebo-controlled evaluation.

32 patients with chronic postprandial dyspepsia were selected for a 4-week controlled double-blind trial of domperidone and a placebo. The patients received either domperidone or a placebo at a dose rate of two 10-mg tablets t.i.d. before meals. A questionnaire was completed at the start of the study, and after 2 and 4 weeks of treatment. Excellent or good improvement was obtained in 71% of the domperidone-treated patients compared to only 13% of the placebo-treated cases. Domperidone was also significantly superior to the placebo when both drugs were compared to previously used medications. Side effects were not reported. It is concluded that domperidone has a beneficial effect on chronic postprandial dyspepsia.
