DPI (Dry Powder Inhaler) #6

   A DPI (Dry Powder Inhaler) is an alternative to the MDI (Metered Dose Inhaler). DPIs are generally for inhaled corticosteroids (ICS) which are often combined with long acting beta agonists (LABA) Unlike the familiar aerosol canister, the DPI requires more patient involvement. It also cannot be used with a "SPACER" (more about this next time).
    After the DPI device is "actuated"  (made available for inhalation) the patient must inhale deeply and hold their breath for 5 to 10 seconds. This can often be a problem for those people (especially COPD patients) who have problems with inhaling deeply.
   Once the powder is inhaled, it is deposited in the lungs and can control the inflammation that causes an attack. That's why we call  them "controllers". By keeping inflammation in control, your use of "rescue" inhalers can be reduced as may your visits to the Emergency Room (so keep using your controllers even when you're feeling fine !!!).
   There are a number of different DPIs which may go by the following names:

Aerolizer®

Diskus®

Flexhaler®

Handihaler®

Rotahaler®

Turbuhaler®

Twisthaler®

I have included a site that describes how to use your DPI as well as your MDI.

   Remember, if you have any questions regarding your "controller" or "rescue" inhaler, call you health care practitioner. If you don't use it correctly, you are jeopardizing your health.
