Asthma inhaler. Sixty year old woman holding an asthma inhaler. Asthma is a condition in which the small airways (bronchioles) in the lungs constrict, making it difficult to breathe. This causes wheezing, coughing and breathlessness. The inhaler is an aerosol pump that releases bronchodilator drugs, which widen the airways.
