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:
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 Accuneb, Alupent, ProAir, 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 or an HFA (CFC-free) MDI. 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.
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
Ipratropium bromide, such as Atrovent, takes longer to act than beta-agonists
and is not used to prevent exercise-induced asthma. Other brands, Combivent
and DuoNeb, contain both ipratropium bromide and albuterol.
Steroids are sometimes given orally (as pills, capsules, or liquids) for 3
- 10 days to help control moderate-to-severe asthma attacks. They take longer
to act, but help prevent additional attacks.
Examples include prednisone, prednisolone, and methylprednisolone.
