A Single Centre Randomized Study Evaluating The Safety And Tolerability Of GSK573719 In Healthy Volunteers

Study Overview
=================
Brief Summary
-----------------
GSK573719 is a high-affinity specific muscarinic receptor (mAChR) antagonist which is being developed for once daily treatment of chronic obstructive pulmonary disease (COPD). The long duration of action of GSK573719 when administered via inhalation in animal models supports the potential for use as a once-daily bronchodilator for COPD

Detailed Description
-----------------
A single-centre, randomised, double-blind, placebo-controlled, dose-ascending, 3-cohort parallel-group study to evaluate the safety, tolerability, pharmacodynamics and pharmacokinetics of GSK573719 administered as single doses (750µg and 1000µg) and repeat doses over 14 days (250µg-1000µg once-daily) of GSK573719 in healthy male and female subjects
