Study hypothesis
Nateglinide is a new oral hypoglycemic agent that increases insulin secretion. In contrast to other oral hypoglycemic agents it mainly decreases postprandial hyperglycemia and it has this effect with lower risk for hypoglycemic events.
Postprandial hyperglycemia appears in the early stages with type two diabetes mellitus and we hypothesise that the use of nateglinide at these stages should improve glycemic control (in terms of HbA1c levels and postprandial hyperglycemia) without any significant increases of its adverse effects.
