Learn About Asthma Inhalers

Overview

Asthma is a chronic inflammatory disease of the airways. Asthma medications are often given through inhalers, which are devices that deliver the medicine directly to the lungs. Let's explore the types of asthma medications given by inhalers and the different inhaler devices along with instructions on how to use each type:

Metered-dose inhalers (MDIs):

MDIs are the most common type of inhaler. They consist of a medication canister inside a plastic case with a mouthpiece.
To use an MDI, you need to press down on the canister, which activates a propellant and delivers one puff of medication as an aerosolized mist.
It is important to aim and fire the device correctly so that the medication goes into your airways rather than landing on the back of your throat.
Many people find it helpful to use a spacer, which is a device attached to the MDI that helps direct the medication into the large and small airways.
Spacers are especially recommended for children to ensure better effectiveness.

Dry powder inhalers (DPIs):

DPIs are another type of inhaler device. They do not use propellants and deliver medication in the form of a fine, dry powder.
DPIs come in disk or cylinder forms that store the medication.
To prepare each dose, you need to twist or click the DPI.
With DPIs, you inhale the powder into your lungs with a fast and deep breath.
It's worth noting that DPIs can be challenging for young children, so doctors usually do not recommend them for this age group.

Soft mist inhalers (SMIs):

SMIs deliver medication as a slow-moving fine mist using mechanical power instead of a propellant.
SMIs consist of two parts: an inhaler and a medication cartridge that needs to be assembled before first-time use.
Similar to DPIs, SMIs require you to inhale the medicine into your lungs with your inward breath.
Compared to MDIs and DPIs, SMIs have more particles and deliver medication more slowly, allowing for more effective delivery into the lungs.

It's important to note that each type of inhaler has its own advantages and disadvantages, and their effectiveness depends on how much medication reaches your lungs. It's always best to consult with your doctor or healthcare provider about which type of inhaler device is most suitable for you and how to properly use it.

Remember, asthma management should always be done under medical supervision. If you have any questions or concerns about your asthma medications or inhaler devices, be sure to ask your doctor for guidance.
