Brief summary
The objective was to investigate a possible drug-drug interaction between BI 10773 and metformin when co-administered as multiple oral doses. Therefore, the relative bioavailabilities of BI 10773 and metformin were determined when both drugs were given in combination compared with BI 10773 or metformin given alone.

Inclusion criteria
* Healthy male volunteers according to the following criteria: Based upon a complete medical history, including the physical examination, vital signs (BP (Blood Pressure), PR (Pulse Rate)), 12-lead ECG (Electrocardiogram), clinical laboratory tests * Age 18 to 50 years (incl.) * BMI (Body Mass Index) 18.5 to 29.9 kg/m2 (incl.) * Signed and dated written informed consent prior to admission to the study in accordance with GCP (Good Clinical Practice) and the local legislation
Exclusion criteria
