Asthma is a very common lung disease that usually begins in childhood, but can occur at any age and is characterized by a chronic inflammatory process in the airways, which makes them more reactive. With certain stimuli, the bronchi become blocked and the symptoms of the disease appear, usually episodes of persistent dry cough, difficulty in breathing or tightness in the chest. Symptoms may be occasional or maintained throughout the year, ranging from mild to severe.
The treatment aims to control the inflammation that exists at the level of the bronchi. Thus, the drugs used have an anti-inflammatory action and the most frequently prescribed are inhaled corticosteroids. Leukotries antagonists, which have a similar effect, may also be used. To either of these two types of drugs it is useful to add a bronchodilator.
Given that asthma is a chronic disease, therapy should be done daily.
