Study on the Safety of BAY 63-2521, How it is Tolerated and the Way the Body Absorbs, Distributes and Gets Rid of the Study Drug Given as a Single Oral Dose of 1 mg Tablet in Participants With Renal Impairment and Healthy Participants Matched for Age-, Gender-, and Weight

Brief Summary

BAY 63-2521 is intended to be used for a disease that affects the blood flow through the lungs. Renal impairment is a common condition in patients with this disease. The goal of the study is to learn more about the safety of BAY 63-2521, how it is tolerated and the way the body absorbs, distributes and gets rid of the study dug given as a single oral dose of 1 mg tablet in participants with renal impairment and healthy participants matched for age-, gender-, and weight

Riociguat, healthy participantsRiociguat (Adempas, BAY 63-2521)Participants with creatinine clearance (CLCR) \>80 mL/min received a single dose of 1 mg (2 x 0.5 mg IR tablet) of riociguat in the fasted state
Riociguat, moderate renal impairmentRiociguat (Adempas, BAY 63-2521)Participants with CLCR 30-\<50 mL/min received a single dose of 1 mg (2 x 0.5 mg IR tablet) of riociguat in the fasted state
Riociguat, severe renal impairmentRiociguat (Adempas, BAY 63-2521)Participants with CLCR \<30 mL/min received a single dose of 1 mg (2 x 0.5 mg IR tablet) of riociguat in the fasted state
Riociguat, mild renal impairmentRiociguat (Adempas, BAY 63-2521)Participants with CLCR 50-80 mL/min received a single dose of 1 mg (2 x 0.5 mg IR tablet) of riociguat in the fasted state
