Title: A Multi-Centre, Randomised, Double-Blind, Placebo-Controlled Dose Finding Study in 4 Parallel Groups to Establish the Efficacy and Safety of an Eight Week Treatment With Itopride Three Times Daily Compared to Placebo in Patients Suffering From Functional Dyspepsia
Brief Summary: This study aims to determine the efficacy and optimal dose of the prokinetic itopride for the treatment of patients with functional dyspepsia.

The study will test in patients with functional dyspepsia the hypothesis that itopride is superior to placebo with regard to the improvement of symptoms.
