How Do Asthma Inhalers Work?

The dramatic symptom that causing wheezing, coughing, difficulty in breathing and shortness of breath is caused by certain event in the airways. One of the events is the lining of the airways beginning to swell, the other is mucus being secreted and muscle surrounding the air ways developing spasm. There are two types of inhalers available in the market that are able to counteract all these types of events in the bronchodilators and open your airways.

Controller Inhalers

The inhalers sometimes referred to as preventers are used to reduce inflammation.  Patients who have been diagnosed with asthma have their airways swollen than those without the condition. In case you buy ventolin online, you will need to use it in the morning and evening. If you come across a trigger that causes your airways to swell even further then the resulting inflammation will not be as severe. The best thing about inhalers is that it can make you less reactive to the triggers. It is recommended, to use the inhalers everyday even if are feeling well.

Reliever Inhalers

This type of inhalers are often recommended and serve as rescue inhalers. In the case where you experience your airways tightening and you find it hard to breathe then the symptoms will go away and you will feel instant relief. The inhalers basically operate by relaxing the muscles and making the airways wider. For those who have problems with inflammation and mucus accumulation then you will need to continue with your controller inhalers as relieve inhalers do not serve that purpose.

MDI

One of the most popular types of inhalers is the metered dose inhalers that operate through the mechanism of a mist coming out when you press down the inhaler. Most often a spacer is used as it helps to hold the chamber that controls the metered device.
