Trial Purpose

The study will be conducted in a single-center, randomized, non-blinded, two-way crossover study in Japanese healthy adult male subjects. 24 subjects will be selected among the subjects undergoing the screening examination conducted within 4 weeks before drug administration of period 1. Single oral doses of riociguat tablet 0.5 mg #501 and riociguat tablet 0.5 mg #511 will be given to selected 24 subjects under the fasting condition with a wash-out interval of 7 days or longer.
One day before the drug administration of each period the subjects will be admitted to the clinical site. During the hospitalization, blood samples for riociguat and its metabolite BAY 60-4552 (M-1) pharmacokinetics will be taken, and the subjects will undergo several tests for safety up to 72 hrs after the administration. Follow up examination will be conducted between Day 7 and Day 10 of period 2.
