About

The purpose of the study is to determine if inhaled iloprost given four times daily can improve symptoms and lung function in adults with mild asthma.

Full description

Animal studies have suggested that prostacyclin may downregulate allergic inflammation, thus providing the scientific basis for trials of inhaled prostacyclin agonists such as iloprost for the treatment of asthma. This study will examine the tolerability of four times daily iloprost on asthma symptoms and pulmonary function over a two week treatment period.
