Allergic asthma is a common chronic condition often treated with inhaled corticosteroids (ICS).  Allergic asthma was induced in mice using intranasal administrations of house dust mite (HDM) three times a week during development.  Fluticasone (ICS) was administered intranasally concurrently with HDM at three doses.  Results showed that low and moderate doses decreased lung inflammation in mice treated with HDM.  ICS also decreased body weight, mimicking a side effect seen in human children.
