Relative Bioavailability of Dabigatran Capsules, Pellets and Oral Solution in Healthy Volunteers

Relative Bioavailability of Dabigatran After Administration of Different Dosage Forms of Multiple Doses of 150 mg Dabigatran Etexilate (Hard Capsule, Granules Resolved in Reconstitution Solution, Pellets on Food) in Healthy Male Volunteers (an Open-label, Randomised, Multiple-dose, Three Way Crossover Study)

To investigate the relative bioavailability of dabigatran etexilate as pellets on food and of dabigatran etexilate as granules resolved in reconstitution solution, each with dabigatran etexilate as capsule following oral administration. To evaluate acceptability and palatability of Pellets sprinkled on food and Oral Liquid Formulation

Inclusion criteria:

3. Body Mass Index 18.5 to 29.9 kg/m2 (incl.)
4. Signed and dated written informed consent prior to admission to the study in accordance with GCP and local legislation

Exclusion criteria:

   • Hemorrhagic disorders or bleeding diathesis
   • Occult blood in faeces or haematuria
   • Trauma or surgery within the last month or as long as an excessive risk of bleeding persists after these events, or planned surgery during trial participation
   • History of arteriovenous malformation or aneurysm
   • History of gastroduodenal ulcer disease or gastrointestinal haemorrhage
   • History of intracranial, intraocular, spinal, retroperitoneal, or atraumatic intraarticular bleeding
   • Anemia at screening
