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. The gene discussed is GCG; the disease is Impaired glucose tolerance.
