Daily Health Advices

Drugs “preventive” are very useful in asthma, reducing airway inflammation, which is the main mechanism by which asthma occurs. When used regularly, producing an overall improvement of asthma, which also includes attacks caused by exercise.

To be effective, these medicines must be used regularly and for long periods of time. Not effective single dose taken before exercise and, usually, may need a week or more before they get benefits. The main drugs in this group are:

Inhaled corticosteroids, such as beclomethasone (Becloforte), fluticasone (Flixotide) and budesonide (Pulmicort). Inhaled corticosteroids are currently the main treatment of bronchial asthma because of its effectiveness and safety.

The receptor antagonists of leukotrienes, such as zafirlukast (Accolate) or montelukast (Singulair). They come in tablets and their effectiveness is difficult to predict, but have proved useful in the control of exercise-induced asthma.

Specific problems of exercise in patients with asthma

The exercise-induced anaphylaxis. This is an extremely rare disease in which the combination of exercise and allergies to food that is eaten immediately before exercise, produce hypotension, collapse and respiratory distress (like serious allergic reactions to peanuts suffered by some patients).

Exercise associated with laughter and excitement can trigger asthma attacks in some asthmatic children (birthday parties, visits from friends or relatives …). If this is predictable, treatment should be anticipated by inhaled bronchodilators.

Occasionally, patients with severe asthma suffer from exercise-induced asthma despite optimal anti-asthmatic treatment. In these cases, it is recommended to make a type of exercise most appropriate and least provocative of asthma.
