How can you use medication to prevent exercise-induced asthma?

There are two ways:

- Short-term protection.

- Long-term protection.

Short-term protection

This protection lasts about 3 or 4 hours when the medication is taken before exercise. Usually, this type of inhaler medication should be used only in cases of mild intermittent asthma, which is not used anti-inflammatory medication (preventive) medication is used only to relieve symptoms (bronchodilators), which also used less once a day. Drugs that can help for short-term protection, we have:

- Inhalers: can help relieve symptoms, which contain short-acting bronchodilators (usually blue), such as salbutamol or terbutaline, and preventing bronchoconstriction when released chemical mediators. Its onset of action is rapid (1 to 5 minutes) and its duration is short (4 to 6 hours at most).

- Long-acting bronchodilators: instead of short-acting bronchodilators can be used long-acting bronchodilators (usually green), such as salmeterol or formoterol, which used every 12 hours provide coverage 24 hours a day. These bronchodilators can only be used in isolation (ie without preventive medication) in special circumstances, as the case of a child with mild asthma, in a sports activity day long and with limited access to short-acting bronchodilators.

Cromolyn sodium and nedocromil are used less often, but may be useful in amateur or professional athletes.
