Safety, Tolerability, Pharmacodynamics and Pharmacokinetics of BEA 2180 BR in Healthy Male Subjects

Study Overview
=================
Brief Summary
-----------------
Main study: To investigate safety, tolerability, pharmacodynamics (PD) and pharmacokinetics (PK) of BEA 2180 BR Sub-study; To investigate whether treatment with 36 μg tiotropium bromide is able to protect of methacholine-induced bronchoconstriction compared to baseline (methacholine challenge at screening).

Official Title
-----------------
Safety, Tolerability, Pharmacodynamics and Pharmacokinetics of Single Rising Inhaled BEA 2180 BR Doses (2.5 μg to 1600 μg Cation Administered With the Respimat®) in Healthy Male Subjects, Alone and Followed by Methacholine Challenge. A Randomised, Double-blind Within Dose Group, Placebo-controlled Study, With a 36 μg Tiotropium Bromide Single Dose Sub-study (Open, Two-fold Crossover).
