Brief summary

The primary objective of this trial is to establish bioequivalence of two fixed dose combination (FDC) tablets (containing medium dose empagliflozin/500 mg metformin \[Test 1\] and low dose empagliflozin/500 mg metformin \[Test 2\]) and of the single tablets (medium dose empagliflozin tablets + Glucophage® 500 mg tablet \[Reference 1\] and low dose empagliflozin tablet + Glucophage® 500 mg tablet \[Reference 2\]) when administered together after a high fat, high caloric meal. The assessment of safety and tolerability will be an additional objective of this trial.
