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