Understanding the Different Types of Inhalers

Being out of breath or struggling to breathe is a frightening experience, and unfortunately for patients with asthma or COPD, it’s a common one.

‍

Luckily, there are tools available to patients who struggle with occasional breathing restrictions. One of the most common treatments for patients with asthma and COPD is inhalers.

‍

In this article, we’ll cover exactly what inhalers are and what different types of inhalers exist. 

‍

What Are Inhalers?

‍

An inhaler is a small, portable device that allows medication, typically corticosteroids or bronchodilators, to be inhaled directly to the lungs. Unlike a nebulizer, inhalers do not need electricity to be operated.

‍

The medications within inhalers can help open your airways or reduce inflammation in the lungs.

What Are the Different Types of Inhalers? 

‍

Inhalers are not ‘one size fits all’. There are a few different kinds that can be used to suit individual patient’s needs. 

‍

• Metered Dose Inhalers
  • Metered dose inhalers, which are also known as MDIs and pMDIs), contain medication in a pressurized canister. When the user pushes a button at the top of the device, the inhaler sends a dose of medicine out of the attached mouthpiece. Then the patient should follow the inhaler's instructions for inhaling the medication. Given that most metered dose inhalers distribute one dose of medicine at a time in a ‘puff’, many patients call these puffers.
• Dry Powder Inhalers
  • Dry powder inhalers, also called DPIs, contain medicine in small capsules that are activated when used. These do not have a propellant component, rather the act of breathing in with your mouth on the mouthpiece pulls in powder into your airways and lungs. There are a few different shapes of dry powder inhalers, so it’s important to read your inhaler's specific instructions.
• Soft Mist Inhalers
  • Soft mist inhalers work by dispensing liquid medicine in the form of a fine mist that is then inhaled through your mouth and into your airways and lungs.

‍

Whichever kind of inhaler your doctor prescribes, it’s always important to follow the instructions and use the inhaler properly to see the best results.
