Dataset from An Open-label, Non-randomised, Three-way Crossover, Single Dose Study to Determine the Absolute Bioavailability of Fluticasone Furoate (FF)/GW642444 Inhalation Powder, in Healthy Subjects

This study is being done to look at the absolute bioavailability of fluticasone furoate and GW642444 inhalation powder when administered in healthy subjects. Bioavailability is determined by measuring the amount of the dose of inhaled medication that reaches the circulation; the amount of inhaled fluticasone furoate and GW642444 powder will be compared to the medication administered intravenously (where bioavailability is 100%).
