Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Adults with stable asthma will be randomised to receive a 10 day course of either 1 x Prednisolone 25mg oral capsule twice daily or 1 x placebo oral capsule twice daily and after a 6 week wash out period subjects will begin a 10 day course of the alternate treatment.
Intervention code [1] 264554 0
Treatment: Drugs
Comparator / control treatment
As this is a cross-over design, all subjects will receive in random order the active drug and the placebo, which is identical in taste and appearance to the prednisolone without containing the active drug, in the form of an oral microcellulose capsule.
Control group
Placebo

Summary
Brief summary
There is some evidence to suggest that oral corticosteroid medications may increase appetite and lead to weight gain. However it is unknown whether people with asthma experience these effects when prescribed oral corticosteroids when their asthma symptoms worsen. This study is designed to examine whether taking oral corticosteroids for a short time affects appetite, dietary intake, body weight or body composition and bone metabolism.
