An Overview of Asthma Inhalers – Types, Effectiveness, Techniques, Cost, Side Effects, and Recommendations

Types of Asthma Inhalers

Asthma inhalers are essential tools in managing asthma symptoms and preventing asthma attacks. There are several types of inhalers available, each serving a specific purpose in the treatment of asthma:

1. Metered-Dose Inhalers (MDIs)

Metered-Dose Inhalers deliver a specific amount of medication in aerosol form with each actuation. They are widely used and contain a pressurized canister that releases the medication when the inhaler is activated. MDIs are commonly prescribed for both short-term relief with bronchodilators and long-term control with corticosteroids.

2. Dry Powder Inhalers (DPIs)

Dry Powder Inhalers deliver medication in a dry powder form that is inhaled by the patient. DPIs do not require coordination of pressing down on the canister, making them easier to use for some patients. They are available as single-dose or multi-dose devices and are commonly used for bronchodilators and anti-inflammatory medications.

3. Nebulizers

Nebulizers convert liquid medication into a mist that is then inhaled through a mask or mouthpiece. They are often used for patients who have difficulty using MDIs or DPIs, such as young children or individuals with severe asthma. Nebulizers are effective in delivering high doses of medication directly to the lungs.

4. Combination Inhalers

Combination Inhalers contain both a long-acting bronchodilator and an inhaled corticosteroid in a single device. They are prescribed for patients who require both bronchodilation and anti-inflammatory effects to manage their asthma symptoms effectively. Combination inhalers simplify the medication regimen for patients with moderate to severe asthma.

Each type of asthma inhaler plays a crucial role in managing asthma symptoms and improving lung function. It is essential for individuals with asthma to work closely with their healthcare providers to determine the most appropriate inhaler type and medication regimen based on their specific needs and asthma severity.

Effectiveness of Inhalers for Asthma

When it comes to managing asthma, inhalers are considered a cornerstone of treatment. They play a crucial role in delivering medication directly to the airways, which helps reduce inflammation and open up the air passages, making breathing easier for individuals with asthma. Inhalers are generally very effective in controlling asthma symptoms and preventing asthma attacks when used correctly.

Types of Inhalers:

There are several types of inhalers available for asthma treatment, including:

  • Reliever Inhalers (Short-Acting Beta Agonists): These inhalers provide quick relief during an asthma attack or when experiencing symptoms like shortness of breath or wheezing.
  • Preventer Inhalers (Steroid Inhalers): These inhalers are used daily to control inflammation in the airways and reduce the frequency and severity of asthma symptoms.
  • Combination Inhalers: These inhalers contain both a steroid and a long-acting bronchodilator to provide both preventive and symptomatic relief.


A study published in the Journal of Allergy and Clinical Immunology found that using inhalers as prescribed can significantly improve asthma control and reduce the risk of exacerbations. The study also highlighted that combination inhalers may be more effective in controlling asthma symptoms compared to using separate reliever and preventer inhalers.

Importance of Proper Inhaler Technique:

While inhalers are effective in managing asthma, it is crucial to use them correctly to ensure optimal drug delivery to the lungs. Incorrect inhaler technique can reduce the effectiveness of the medication and lead to poor asthma control. According to the American Academy of Allergy, Asthma & Immunology, up to 94% of patients may not use their inhalers correctly.

Key Points on Inhaler Effectiveness:

  • Consistent Use: Using inhalers regularly as prescribed by a healthcare provider is crucial for maintaining asthma control.
  • Monitoring Symptoms: Paying attention to asthma symptoms and seeking medical advice if symptoms worsen despite inhaler use is important.

After using a corticosteroid inhaler, rinse your mouth with water to prevent the risk of oral thrush.

By following these proper techniques, you can ensure that your asthma inhaler is effectively delivering medication to manage your asthma symptoms.

For more detailed instructions on using specific types of inhalers, consult the manufacturer’s guidelines or speak with your healthcare provider.

Mechanism of Action of Asthma Inhalers

Asthma inhalers work by delivering medication directly to the lungs to reduce inflammation and open the airways, making it easier to breathe. There are two main types of asthma inhalers:

  • Reliever inhalers: This type of inhaler contains short-acting beta-agonists (SABAs) that quickly relax the muscles around the airways, providing immediate relief during an asthma attack. These inhalers are used as-needed for quick relief.
  • Controller inhalers: Controller inhalers typically contain corticosteroids, which work to reduce inflammation in the airways over time, helping to prevent asthma symptoms and attacks. These inhalers are used on a daily basis.

When a person inhales the medication from the inhaler, it travels into the lungs where it can act directly on the airway muscles or reduce inflammation in the airways. For example, SABAs like albuterol bind to beta-2 receptors on the muscle cells surrounding the airways, causing them to relax quickly and open up, allowing for easier breathing. Corticosteroids work by reducing the production of inflammatory mediators in the airways, helping to decrease swelling and mucus production over time.

It’s important to use inhalers correctly to ensure the medication reaches the lungs where it can be most effective. Proper inhaler technique involves shaking the inhaler, exhaling fully before inhaling the medication, pressing the canister while inhaling slowly and deeply, holding your breath for a few seconds, and then exhaling slowly. Incorrect technique can result in reduced medication delivery and less effective treatment.

According to the American Lung Association, using a spacer device with the inhaler can help improve medication delivery and reduce the risk of side effects like oral thrush. A spacer is a chamber that attaches to the inhaler and helps to ensure that the medication is properly inhaled into the lungs.

Studies have shown that adhering to proper inhaler technique and using controller inhalers regularly can help improve asthma control and reduce the frequency of asthma attacks. In a survey conducted by the Asthma and Allergy Foundation of America, 71% of people with asthma reported that using their inhaler properly improved their asthma symptoms.
