Exercise-induced Asthma - Treatment

Treatment

Further information: Asthma#Treatment

As with any asthma, the best treatment is avoidance of conditions predisposing to attacks, when possible. In athletes who wish to continue their sport or do so at times in adverse conditions, preventive measures that can be taken include altered training techniques and medications.

Some athletes take advantage of the refractory period by precipitating an attack by "warming up," and then timing their competition such that it occurs during the refractory period. Step-wise training works in a similar fashion. An athlete warms up in stages of increasing intensity, using the refractory period generated by each stage to get up to a full workload.

Concerning medication, it should be recognized that treatment of EIB has been extensively studied in asthmatic subjects over the last 30 years, but not so in athletes with EIB. Thus, it is not known whether athletes with EIB or ‘sports asthma’ respond similarly to subjects with classical allergic or nonallergic asthma. However, there is no evidence supporting different treatment for EIB in asthmatic athletes and nonathletes.

The most common medication approach is to use a beta agonist about twenty minutes before exercise. Some physicians prescribe inhaled anti-inflammatory mists such as corticosteroids or leukotriene antagonists, and mast cell stabilizers have also proven effective. A randomized crossover study compared oral montelukast with inhaled salmeterol, both given two hours before exercise. Both drugs had similar benefit but montelukast lasted 24 hours.

Famous quotes containing the word treatment:

    I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.
    Hippocrates (c. 460–c. 370 B.C.)

    The motion picture made in Hollywood, if it is to create art at all, must do so within such strangling limitations of subject and treatment that it is a blind wonder it ever achieves any distinction beyond the purely mechanical slickness of a glass and chromium bathroom.
    Raymond Chandler (1888–1959)

    To me, nothing can be more important than giving children books, It’s better to be giving books to children than drug treatment to them when they’re 15 years old. Did it ever occur to anyone that if you put nice libraries in public schools you wouldn’t have to put them in prisons?
    Fran Lebowitz (20th century)
