Aoki et al. [92] examined the effect of the administration of mosapride citrate on plasma incretin levels in men with normal glucose tolerance (NGT) or impaired glucose tolerance (IGT) and showed that the AUCs of the plasma active and total GLP-1 levels were significantly higher in the M (mosapride citrate 20 mg) group than in the control (no drug) group. This evidence concerns the gene GLP1R and Impaired glucose tolerance.
