Inhaled
medications, nebulizers and metered dose inhalers
The most
effective delivery system for asthma medications is inhalation. The
nebulizer is the most effective; the metered dose inhaler most convenient.
A nebulizer,
which you can obtain from our office, is simply a machine that compresses
air and sends it through a small length of tubing into a receptacle
where the stream of fast moving compressed air hits a pool of medication
creating a mist of air. That medication is then sent through a mouthpiece
or mask to be inhaled by the patient.

The tubing,
mouthpieces, masks and receptacles are washable and ultimately replaceable.
Currently,
short acting bronchodilators such as albuterol
and the newer isomer of albuterol (Xopenex) are the only bronchodilators
that are available for this delivery system.
Controller
medications, cromylyn (Intal) and corticosteroids (Pulmicort) are also
available in a liquid form.
There
are a variety of short acting albuterol metered dose inhalers as well
as versions of corticosteroids and cromolyn
. Each of the metered dose inhalers delivers a more reliable and more
effective dose of medication if it is used in conjunction with a spacer.
Instead of having the metered dose inhaler spray directly into the mouth,
where a large percentage remains in the back of the throat and is inactived,
the spacer allows a far greater percentage of the medication to be inhaled
directly into the lungs. Undesired side effects of the residue in the
mouth can thus be avoided.

The metered
dose inhaler is inserted into one end of the spacer, the metered dose
inhaler is activated to release the dose into the chamber, and then
the patient inhales the medication through the mouthpiece at the other
end. The spacers make it especially easy for children to use an inhaled
medication safely and reliably.
