Efficacy and safety of the peripheral kappa agonist fedotozine versus placebo in the treatment of functional dyspepsia.


ABSTRACT: BACKGROUND: Peripheral kappa receptor agonists may provide a new therapeutic approach for the treatment of functional dyspepsia. AIMS: To evaluate, in a large multicentre trial, the use of the kappa receptor agonist fedotozine to improve symptoms associated with functional dyspepsia. METHODS: Two or more of the following persistent symptoms were required for inclusion: epigastric pain, early satiety, epigastric fullness or distension, nausea, vomiting, and a feeling of slow digestion. On completing a two week placebo washout, 271 patients were randomised into two groups to receive 30 mg fedotozine three times daily or placebo for six weeks under double blind conditions. RESULTS: The improvement in the overall intensity of dyspeptic symptoms (main efficacy criterion) was significantly more pronounced in the fedotozine group (p = 0.002) compared with placebo, as was epigastric pain (p = 0.004) and nausea (p = 0.01); the improvement in postprandial fullness was nearly significant (p = 0.052). Inability to finish a meal and slow digestion were unaffected. The patient global score, the average of the five individual symptoms, was notably ameliorated with fedotozine (p = 0.021). The safety of fedotozine was excellent. CONCLUSIONS: Fedotozine at 30 mg three times daily is safe and more effective than placebo for the relief of key symptoms associated with functional dyspepsia.
