A Two-part Study to Determine the Relative Bioavailability of Dabigatran Etexilate 150 mg Bid (Capsules) With and Without 600 mg Quinidine Sulfate Tablets (Part 1) and to Measure the Effect of Quinidine as a Probe Inhibitor of P-glycoprotein on the Absorption of Fexofenadine, a Probe Substrate of P-glycoprotein (Part 2) in Healthy Male and Female Volunteers (an Open-label, Randomised, Two Times Two-way Crossover Study)
Part 1: To investigate the effect of quinidine, a P-glycoprotein (P-gp) probe inhibitor on the bioavailability of dabigatran etexilate,
