A Study to Find Out How YM150 is Absorbed Into and Eliminated From the Body in Healthy Male Subjects
An Open Label Study to Evaluate the Pharmacokinetics of YM150 After a Single Oral Dose of C14-labeled YM150 in Healthy Male Subjects
The study aims to observe how YM150 was absorbed, distributed and excreted after dosing with a radio labeled drinking solution.
Healthy male subjects are admitted on Day 0. Subjects receive a single oral dose of 14C-labeled YM150 in the morning of Day 1 and remain in the unit for 7 days (6 nights). Blood, plasma, urine and feces samples are collected until 120 hrs after dosing for analysis of 14C-labeled radioactivity, YM150, YM-222714 and other metabolites. Expired air is collected as well for assessment of 14C-radioactivity.
