 Miglitol reduces postprandial glucose levels. Serial changes in plasma glucose levels before and after breakfast. The treatment with miglitol was discontinued in four subjects and the meal tolerance test after treatment was not carried out with them. Thus, the postprandial blood glucose data from these four cases are not included. In two of these four discontinued cases, only fasting blood glucose level was measured and included as fasting blood glucose level. Data are mean ± SD. *P < 0.01, **P < 0.001 compared with before treatment.
