Investigation of the Metabolism and Pharmacokinetics of 10 mg [14C] BI 1356 Administered Orally Compared to 5 mg [14C] BI 1356 Administered Intravenously in Healthy Male Volunteers in an Open Label, Single-dose and Parallel Study Design

To determine the basic pharmacokinetics of BI 1356 BS, its metabolite CD 1750 XX and radioactivity including excretion mass balance, excretion pathways and metabolism following the intravenous and oral administration of [14C] BI 1356 BS
