Asthma Treatment and Medication
Asthma is a chronic lung disease that effects over 30 million
Americans alone and researchers estimate that 10 - 15% of the
world population suffers from asthma. People with asthma have
extra sensitive or hyper-responsive airways. The airways become
irritated and narrow and constrict during an asthma attack,
causing increased resistance to airflow, and obstructing the
flow of the air to and from the lungs.
Most often asthma must be treated with prescription medicine.
There are two main types of medicines for the treatment of
asthma. Quick relief medicines, also called relievers, give
rapid, short-term relief and are taken when asthma symptoms
worsen potentially leading to an asthma attacks. The effects of
these medicines are felt within minutes. Long-term control
medicines, also called preventers, are taken every day, usually
over long periods of time, to control chronic symptoms and to
prevent asthma attacks. The full effects of these medicines are
felt after taking them for a few weeks. People with persistent
asthma need long-term control medicines.
Some asthma drugs treat asthma by resembling two of our
hormones. These two hormones are adrenaline (epinephrine in the
USA) and hydrocortisone (a steroid).
Adrenaline (epinephrine) is pumped into our bloodstream when we
have a sudden fright or emergency. It is the quick-acting
hormone from the middle of the adrenal glands near our kidneys.
It makes your pulse race, your heart thump, and readies your
body for emergency action. In asthma, the medicines which
resemble adrenaline quickly relieve asthma for a short time.
Hydrocortisone comes from the outer part of our adrenal glands,
called the 'cortex'. It is also partly an "emergency hormone"
but it works much more slowly, for much longer, and in a
completely different way to adrenaline. Medicines which resemble
hydrocortisone slowly allow the lining of air tubes in an asthma
sufferer to become normal. As a result, your asthma becomes less
severe and you are less likely to get asthma attacks. So these
steroid medicines are called preventers. There are other asthma
'preventers', but the steroids are the most powerful.
Quick relief medicines are used only when needed. A type of
quick relief medicine is a short-acting inhaled bronchodilator.
Bronchodilators work by relaxing the muscles that have tightened
around the airways. They help open up airways quickly and ease
breathing. They are sometimes called "rescue" or "relief"
medicines because they can stop an asthma attack very quickly.
These medicines act quickly but their effects only last for a
short period of time. People with asthma should take quick
relief medicines when they first begin to feel asthma symptoms
like coughing, wheezing, chest tightness, or shortness of
breath. Anyone who has asthma should always have one of these
inhalers nearby in case of an attack. For severe attacks, your
doctor may use steroids to treat the inflammation.
The most effective, long-term control medication for asthma is
an inhaled corticosteroid. This medicine reduces the swelling of
airways that makes asthma attacks more likely. Inhaled
corticosteroids are the preferred treatment for controlling
mild, moderate, and severe persistent asthma. They are safe when
taken as directed by your doctor. Inhaled medicines go directly
into your lungs where they are needed. There are many kinds of
inhalers that require different techniques, and it is important
to know how to use your inhaler correctly. In some cases,
steroid tablets or liquid are used for short times to bring
asthma under control. The tablet or liquid form may also be used
to control severe asthma.
Many people with asthma need both a short-acting bronchodilator
to use when asthma symptoms worsen rapidly and long-term daily
asthma control medication to treat the ongoing inflammation.
Over time, your doctor may need to make changes in your asthma
medication. You may need to increase your dose, lower your dose,
or try a combination of medications. Be sure to work with your
doctor to find the best treatment for your asthma. The goal is
to use the least amount of medicine necessary to control your
asthma and to find the right medicine for you.
