To investigate safety and pharmacokinetics of mitiglinide and metformin in a fixed-dose combination of mitiglinide/metformin, compared with free combination of mitiglinide and metformin in healthy male subjects.

The Korean clinical practice guidelines on DM recommend that a second oral agent with a different mechanism of action be combined to the regimen when adequate glycemic control is difficult to achieve with an oral hypoglycemic agent accompanied dietary therapy. Therefore, a concurrent administration of metformin, a inhibitor of gluconeogenesis, and mitiglinide, an insulin secretagogue, could be an effective and ideal regimen for management of diabetes.
