Treatment: Quick-Relief Drugs

You need a quick-relief drug when you're coughing, wheezing, having trouble breathing, or otherwise having an asthma episode (asthma attack). These drugs work very fast to control asthma symptoms. They are also referred to as "rescue" drugs.

Here are the main types:

Short-acting beta-agonists

The short acting beta-agonists are the most effective and most widely used drugs for treating asthma attacks. They also can be used just before exercising to help prevent exercise-induced symptoms. They work by relaxing the muscles that tighten around the bronchial tubes during an attack. (The drug is a "bronchodilator.")

If you find that you are increasingly relying on these drugs or using more than one canister a month, your asthma probably is not under control, and your daily control drugs should be evaluated.

Albuterol is the most commonly used short-acting beta-agonist and is the ingredient in Proventil, and Ventolin. A purer form of albuterol, called levalbuterol, is now available (Xopenex), and appears to require lower doses with longer action and fewer side effects. Levalbuterol is delivered with a nebulizer and can be used by children ages 6 and up. Maxair (pirbuterol) is another example of a short-acting beta-agonist. IMPORTANT NOTE: Short-acting beta agonists are NOT formulated the same as "long-acting" beta agonists, which are used in the daily control of asthma.

Ipratropium bromide

This drug, which is also a bronchodilator, is often the next choice for quick relief and is given to people who do not tolerate beta-agonists. It is also used for people whose asthma is triggered by beta-blocker medication for the heart.

Ipratropium bromide, such as Atrovent, takes longer to act than beta-agonists and is not used to prevent exercise-induced asthma. Another brand, Combinvent, contains both ipratropium bromide and albuterol.

Oral steroids

Steroids are sometimes given orally (as pills, capsules, or liquids) for 3 to 10 days to help control moderate to severe asthma attacks. They take longer to act, but help prevent additional attacks.

Examples include Orasone (prednisone), Prelone and Pediapred (prednisolone), and Medrol (methylprednisolone).
