Relative Oral Bioavailability of BI 44847 as Suspension Compared to Tablet and the Influence of Food Anf of BI 44847 as Solution Compared to Tablet in Healthy Male Volunteers

Relative Oral Bioavailability of 400 mg BI 44847 as Suspension Compared to 400 mg BI 44847 as Tablet and the Influence of Food (Standardised High Fat Breakfast) on the Tablet in a Single Dose, Open-label, Randomised Three-way Crossover Trial and Relative Oral Bioavailability of 40 mg BI 44847 as Solution Compared to 40 mg BI 44847 as Tablet in Healthy Male Volunteers in a Single Dose, Open-label, Randomised Two-way Crossover Trial

Study to investigate the relative oral bioavailability of 400 mg BI 44847 as suspension vs. 400 mg BI 44847 as tablet, to investigate a food effect on the 400 mg tablet pharmacokinetic (PK) and to investigate relative oral bioavailability of 40 mg BI 44847 as solution vs. 40 mg BI 44847 as tablet.
