Main Varieties of Asthma Inhalers

A device used for handling an asthma situation is called the asthma inhaler, which generally contains an asthma medication that can treat asthma symptoms. Usually used asthma inhalers are the metered dose inhalers. These inhalers include a carrier material that can suspend the drug, carry the drug in small drops to be able to reach the small airways present in a person’s lungs.

Until now, the metered dose inhaler was full of CFC, which was the propellant as well as solvent used for curing the asthma patient. There is at present a slow change towards using halo carbons in its place. It has also been establish that a many of inhalers which had increased absorption as well as improved size of the particles had improved potency to a high of 180 percent.

Some other asthma inhalers involve micronized powder packages. These packages may be used in single dose quantities controlled in blisters, or compressed pellets that are automatically freed as well as suspended and inhaled into the lungs unswervingly using the patient’s own breath. Such asthma inhalers are costly as compare to metered dose inhalers and suffer from a disadvantage in that when under attack, the patient may not be capable to produce adequate airflow to draw in the medication. They are, however, not likely to affect the ozone layer.

An asthma inhaler will typically contain a reservoir at the base to hold the drug powder. To fill a single dosage into the inhalation chamber, a twist grip requires to be twisted back and forth, and a numerical dose counter give the patient with information on the remaining doses left. When the background color becomes red, indicates that there are only twenty doses left. Latest asthma inhalers have been found to provide consistent doses each time it is used.

While comparing the powder inhaler with the aerosol inhaler, it may be eminent that the powder inhaler may demonstrate to be more effectual. In powder inhalers, the powder is capable to reach the airways better than the sprayed aerosol, which often gets isolated in the mouth itself. But, the dry powder inhalers are becoming outdated, since they may only deliver less than ten percent of the powder to the lungs, while newer versions of the asthma inhaler are being considered to provide as much as thirty percent of the drug, deep into the lungs.
