Types of respiratory inhalers available in 2017

Asthma inhalers come in several types:

  • Metered Dose Inhalers (MDIs): These are the most commonly used inhalers and deliver a specific amount of medication with each spray. Common MDIs include Albuterol and Fluticasone.
  • Dry Powder Inhalers (DPIs): These inhalers deliver medications in powder form. Examples include Pulmicort and Symbicort.
  • Nebulizers: These devices convert liquid medication into a fine mist that can be inhaled through a mask or mouthpiece. They are often used for severe asthma cases or in young children. Examples include Xopenex and Ventolin.

A survey conducted by the Allergy and Asthma Network found that in 2017, the most commonly prescribed inhalers were MDIs, followed by DPIs and nebulizers. However, the choice of inhaler type depends on various factors such as the patient’s age, severity of asthma, and ability to use the device effectively.

According to the Asthma and Allergy Foundation of America, approximately 25 million Americans have asthma, and inhalers are a vital part of managing the condition. Choosing the right type of inhaler can significantly impact the effectiveness of asthma treatment.

Mechanism of How Inhalers Work to Alleviate Asthma Symptoms

Respiratory inhalers are a vital component of asthma management, providing fast-acting relief for individuals experiencing asthma symptoms. These inhalers work by delivering medication directly to the lungs, where it can quickly reduce inflammation and open up the airways, making breathing easier for the individual.

There are two main types of inhalers commonly used to treat asthma: metered-dose inhalers (MDIs) and dry powder inhalers (DPIs). MDIs are the most commonly prescribed inhalers and consist of a pressurized canister containing the medication, a mouthpiece, and a propellant. When the individual presses down on the canister, a measured dose of medication is released as a fine mist, which is then inhaled into the lungs.

The medication in the inhaler is typically a bronchodilator, which helps to relax the muscles around the airways, allowing them to open up and facilitate easier breathing. This process helps to alleviate symptoms such as wheezing, shortness of breath, and chest tightness that are characteristic of an asthma attack.

Another type of medication commonly found in inhalers is corticosteroids, which work to reduce inflammation in the airways, making them less sensitive to triggers that can lead to asthma symptoms. By combining bronchodilators and corticosteroids in a single inhaler, individuals with asthma can effectively manage their symptoms and prevent exacerbations.

Research has shown that using inhalers as directed can significantly improve asthma control and reduce the frequency and severity of asthma attacks. It is important for individuals with asthma to work closely with their healthcare provider to develop an asthma action plan that includes the appropriate use of inhalers to manage their condition effectively.

According to a survey conducted by the American Academy of Allergy, Asthma & Immunology, over 26 million Americans have asthma, with approximately 8% of adults and 9.5% of children affected by the condition.

Overall, respiratory inhalers play a crucial role in asthma management by providing fast-acting relief and long-term control of symptoms. Understanding how inhalers work and using them appropriately can help individuals with asthma lead healthier, more active lives.

Overview of Metered Dose Inhalers for Asthma Management

Metered dose inhalers (MDIs) are one of the most common types of inhalers used for managing asthma symptoms. MDIs deliver medication directly into the lungs in a measured dose, making them highly effective in providing relief for asthma sufferers. These inhalers consist of a pressurized canister that contains the medication and a mouthpiece for administration.

Mechanism of Action

MDIs work by releasing a specific amount of medication when the canister is pressed, leading to the formation of a fine mist that can be inhaled into the lungs. The medication then helps to reduce inflammation in the airways, relax the muscles surrounding the airways, and improve overall breathing capacity.

Benefits of Metered Dose Inhalers

– Portable and convenient: MDIs are compact and easy to carry around, allowing asthma patients to have quick access to their medication when needed.
– Quick relief: The fast-acting nature of MDIs allows for quick symptom relief during asthma attacks or flare-ups.
– Proper dosing: Metered dose inhalers provide a precise dosage of medication, ensuring that the correct amount is delivered with each use.

Common Medications in MDIs

Some of the common medications used in MDIs include:
– Albuterol (Ventolin, Proventil)
– Fluticasone (Flovent)
– Budesonide (Pulmicort)
– Salmeterol (Serevent)

Instructions for Using a Metered Dose Inhaler

It is important for asthma patients to follow these steps when using a metered dose inhaler:
1. Shake the inhaler well before each use.
2. Remove the cap and hold the inhaler upright.
3. Breathe out gently to empty the lungs.
4. Press down on the canister while inhaling deeply and slowly.
5. Hold your breath for a few seconds before exhaling.
