Relative Bioavailability of BI 10773 and Glimepiride in Healthy Male Volunteers

Relative Bioavailability of Both BI 10773 and Glimepiride After Co-administration Compared to Multiple Oral Doses of BI 10773 (50 mg q.d.) Alone and a Single Dose of Glimepiride (1 mg) Alone in Healthy Male Volunteers (an Open-label, Randomised, Crossover, Clinical Phase I Study)

The objective was to investigate whether there was a drug-drug interaction between BI 10773 and glimepiride when co-administered. Therefore, the relative bioavailabilities of BI 10773 and glimepiride were determined when both drugs were given in combination compared to multiple oral doses of BI 10773 once daily alone and a single oral dose of glimepiride given alone.
