[L-sulpiride Versus Metoclopramide in Functional Dyspepsia: a Randomized Double-blind Study]

Fifty patients suffering from functional dyspepsia have been treated in a double-blind study either with 1-sulpiride (75 mg die per os) or with metoclopramide (30 mg die per os) for 30 days. The frequency and severity of the symptoms in the two patient groups were similar. The administration of either drug was followed by a reduction of the symptoms, but 1-sulpiride was more effective on nausea, headache, pyrosis, epigastric pain, and showed an earlier effect than metoclopramide in inducing total regression of symptoms.
