Asthma, AMP challenge
Brief summary
Inhaling AMP causes an inflammatory response in the lung. This study will investigate whether 5-days of treatment with fluticasone propionate protects the lung from responding to the AMP in this way.
Detailed description
A randomised, double-blind, placebo-controlled, incomplete block, 4-period crossover study to investigate the effects of 5-day repeat inhaled doses of fluticasone propionate (BID, 50-2000 mcg) on airway responsiveness to adenosine-5'-monophosphate (AMP) challenge when delivered after the last dose in mild asthmatic subjects
