About

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.
