简要总结
Primary objectives: To determine the basic pharmacokinetics of BEA 2180 BR, its metabolites CD 1975 ZW and CD 1976 ZW and radioactivity including excretion mass balance, excretion pathways and metabolism following the oral and intravenous administration of [14C] BEA 2180 BR
Secondary objectives: To determine safety and tolerability following single dose oral and iv administration of BEA 2180 BR in healthy male volunteers.
