Clinical efficacy and safety of levosulpiride and domperidone in the management of chronic functional dyspepsia: A double-blind, randomized clinical trial

Forty patients with functional dyspepsia were treated under double-blind conditions with levosulpiride (75 mg/day) or with domperidone (60 mg/day) for four weeks. Levosulpiride, but not domperidone, significantly reduced nausea and vomiting; both drugs were efficacious in significantly reducing the other symptoms. Levosulpiride, but not domperidone, significantly shortened gastric emptying time (determined by the ultrasonographic method). Neither drug modified the presence of Helicobacter pylori in gastric mucosa. Our study confirmed that levosulpiride represents a good choice in patients with functional dyspepsia, especially when delayed gastric emptying, nausea, and vomiting are present.
