Study Summary
The purpose of this study is to determine the beneficial effect of n-acetylcysteine (NAC), an inhaled medication that breaks down mucus, on lung function. NAC is a medication approved by the US Food and Drug Administration (FDA) for the treatment of chronic diseases of the respiratory system, including asthma. With CT lung imaging, the investigators seek to identify a subgroup of patients with asthma with a 'mucus' profile. This is a single-arm study which means all participants will receive the same treatment.
Primary Outcome
Post-treatment FEV1 is reported. FEV1 is measured via spirometry.
