Improper Use of Inhalers Causes Problems
Scientists believe that they may have
solved the mystery behind misuse of
inhalers. Airway opening inhalers such
as albuterol, ventolin, and salbutamol
appear to cause a biochemical reaction
that aggravates swelling in the body's
airway. The swelling, in turn, can block
airflow and make breathing harder.
A new generation of medications
known as beta2-agonists has allowed
asthma patients to breathe more easily by
opening up the airways. Physicians, however,
have known for a long time that
those patients can relapse if they do not
use another type of inhaler that reduces
inflammation in the airway. The bronchodilating
inhalers-known as "relievers"-are
a good temporary measure "because
they save lives while you do the things you
need to do to reduce inflammation," said
pulmonologist Thomas Stibolt, MD, of the
Kaiser Permanente health plan in Portland,
Ore. Patients, however, are often so
impressed by the quick response of the
inhalers that they do not use the anti-inflammation
inhalers-known as "controllers"-
that prevent a recurrence.
"They say this medication isn't doing
anything," Dr. Stibolt said. "But it's preventing
a problem, not relieving it. The
medications they desperately need to
be on don't do anything they notice." As
the inflammation on the walls of the airway
gets worse, the reliever inhalers fail
to work properly as they become overwhelmed.
"It actually worsens the problem
in the long term." Asthma patients
need to understand the importance of
using both the reliever and controller
inhalers.
