Everything You Need to Know About Asthma Inhalers – Types, Usage, and Maintenance

What are asthma inhalers and how do they work

Asthma inhalers are devices that deliver medication directly into the lungs to help relieve symptoms of asthma, a chronic respiratory condition characterized by inflammation and narrowing of the airways. Inhalers are a common method of administering asthma medication as they allow for rapid delivery and targeted action in the lungs.

There are two main types of asthma inhalers: metered-dose inhalers (MDIs) and dry powder inhalers (DPIs). MDIs contain a pressurized canister that releases a specific dose of medication when activated, while DPIs use a powdered form of the medication that is inhaled into the lungs.

When a person uses an inhaler, they inhale the medication through their mouth and into their lungs. The medication works by relaxing the muscles around the airways and reducing inflammation, making it easier to breathe. Common medications found in asthma inhalers include albuterol, which is a short-acting bronchodilator that helps to open the airways quickly, and salmeterol, which is a long-acting beta-agonist that provides prolonged relief.

It is important for individuals with asthma to use their inhalers as prescribed by their healthcare provider to manage symptoms and prevent asthma attacks. Inhaler technique is also crucial for ensuring the medication reaches the lungs effectively. Proper use of inhalers can help improve lung function, reduce symptoms, and enhance quality of life for individuals living with asthma.

Understanding the Drug Inside Asthma Inhalers

Asthma inhalers are medical devices that deliver medication directly to the lungs to help relieve asthma symptoms and manage the condition. The drug inside asthma inhalers is typically one of two types of medication: albuterol or salmeterol.


Albuterol is a short-acting beta agonist that works by relaxing the muscles in the airways, making it easier to breathe. It is commonly used as a rescue inhaler to provide quick relief during asthma attacks or sudden symptoms. Albuterol acts rapidly, usually within minutes, to open up the airways and improve breathing.

Albuterol inhalers are available in different forms, including metered-dose inhalers (MDIs) and dry powder inhalers (DPIs). MDIs deliver a measured dose of medication with each spray, while DPIs require the user to inhale the powder form of the drug.


Salmeterol is a long-acting beta agonist that works by relaxing the muscles in the airways over a longer period of time. It is typically used as a maintenance inhaler to help control asthma symptoms and prevent asthma attacks. Salmeterol is not meant for fast relief during an acute asthma episode but is used regularly to keep airways open and prevent symptoms from occurring.

Like albuterol, salmeterol inhalers come in both MDI and DPI forms. They are usually prescribed for daily use to help manage asthma symptoms and improve lung function over time.

It’s important to use asthma inhalers as prescribed by a healthcare provider and to understand the specific type of medication inside the inhaler. Albuterol and salmeterol have different purposes and should not be used interchangeably without medical guidance.

Why are there no generic asthma inhalers available in the US market

Generic asthma inhalers have been a topic of discussion in the healthcare industry, particularly in the United States. Unlike other medications where generics are widely available, asthma inhalers are still predominantly brand-name products. There are several reasons for the lack of generic asthma inhalers in the US market:

  • Patent protection: Many asthma inhalers contain specific drug formulations that are covered by patents held by pharmaceutical companies. These patents protect the proprietary drug delivery mechanisms and formulations, making it difficult for generic manufacturers to replicate the exact product.
  • Regulatory hurdles: The process of gaining approval for generic inhalers is complex and requires extensive testing to demonstrate bioequivalence with the brand-name products. This can be a lengthy and costly process, leading many generic manufacturers to focus on other medications with potentially higher profit margins.
  • Market exclusivity: Pharmaceutical companies often have market exclusivity rights for a certain period after a new drug is introduced. During this time, generic versions of the medication cannot be marketed, limiting competition in the asthma inhaler market.
  • Complexities in inhaler design: Asthma inhalers are not just containers for medications but complex devices that deliver precise doses of drugs to the lungs. Replicating the design and functionality of these inhalers can be challenging for generic manufacturers.

It is essential for patients to understand that while generic asthma inhalers may not be available in the US market, there are still options for managing asthma symptoms effectively. Consulting with healthcare providers can help individuals find the most suitable treatment options, including brand-name inhalers, to maintain optimal asthma control.

How often should asthma inhalers be used and best practices for inhaler usage

Managing asthma effectively involves using your inhaler as prescribed by your healthcare provider. The frequency of inhaler usage can vary depending on the type of inhaler and the severity of your asthma. In general, quick-relief inhalers, also known as rescue inhalers, are used as needed for sudden asthma symptoms, such as wheezing or shortness of breath. These inhalers typically contain medications like albuterol, which work quickly to open up your airways.

On the other hand, maintenance inhalers are used on a regular schedule to control persistent asthma symptoms and prevent asthma attacks. These inhalers usually contain medications like salmeterol, which help reduce airway inflammation and keep asthma symptoms under control.

It is essential to follow your healthcare provider’s instructions on how often to use your asthma inhaler. Typically, quick-relief inhalers should be used when you experience asthma symptoms, while maintenance inhalers are used daily, even when you are feeling well. Skipping doses of your maintenance inhaler can increase the risk of asthma exacerbations.

Here are some best practices for inhaler usage:

  • Use a spacer device if prescribed by your healthcare provider to ensure that the medication reaches your lungs effectively.
  • Shake the inhaler well before each use to ensure proper dispersion of the medication.
  • Prime the inhaler if it is a new inhaler or has not been used for a while, as instructed by the manufacturer.
  • Keep track of your inhaler use and refill it promptly when running low to avoid running out of medication.
  • Rinse your mouth with water after using a steroid inhaler to reduce the risk of oral thrush.
