RecruitingPhase 2Drug trialEscitalopram in Asthma Patients With Frequent ExacerbationAntidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), such as escitalopram are widely used for mood and anxiety disorders. However, they have also been explored, with promising findings, for a variety of disorders outside of psychiatry. Clinical studies of SSRIs in depressed people with asthma were associated with decreased asthma exacerbations and improvement in asthma control. In this study, the number of asthma exacerbations will be assessed as the primary outcome measure in patients using escitalopram vs. placebo.
