Asthma inhaler. Artwork of an inhaler to treat an asthma attack. Asthma is a condition in which the small lung airways (bronchioles) constrict,making it difficult to breathe. This causes wheezing,coughing and breathlessness,and can be dangerous. The inhaler releases a bronchodilator drug that is inhaled into the lungs and widens the airways. Asthma attacks can be brought on by exercise,allergic reactions and cold weather | |
