Bioavailability of Different Applications of Dabigatran in Healthy Volunteers

To determine the relative bioavailability of 150 mg of dabigatran etexilate as pellets on food and of 150 mg of dabigatran etexilate as powder resolved in reconstitution solution, both with 150 mg of dabigatran etexilate as capsule in healthy volunteers

* Excessive physical activities (within one week prior to administration or during the trial)
* Any laboratory value outside the reference range that was of clinical relevance
* Inability to comply with dietary regimen of trial site

* A history of additional risk factors for Torsade de Pointes (e.g. heart failure, hypokalemia, family history of Long QT Syndrome)
* For female subjects:

  * Positive pregnancy test, pregnancy or planning to become pregnant during the study or within 1 month after study completion
