Types of Asthma Preventer Inhalers

When it comes to managing asthma, preventer inhalers play a crucial role in controlling the condition and reducing the frequency and severity of asthma attacks. There are several types of preventer inhalers available, each containing different active ingredients to help manage asthma symptoms effectively.

Corticosteroid Inhalers

Corticosteroid inhalers are among the most common types of preventer inhalers prescribed for asthma patients. These inhalers contain corticosteroids, such as beclomethasone, fluticasone, or budesonide, which work by reducing inflammation in the airways and preventing asthma symptoms. Corticosteroid inhalers are usually used on a daily basis to control asthma and improve lung function over time.

Combination Inhalers

Combination inhalers are another type of preventer inhaler that contain a combination of corticosteroids and long-acting beta-agonists (LABA). LABAs help relax the muscles in the airways, making it easier to breathe, while corticosteroids reduce inflammation. Examples of combination inhalers include Advair (fluticasone-salmeterol) and Symbicort (budesonide-formoterol).

Leukotriene Inhibitors

Leukotriene inhibitors, such as montelukast, are oral medications that can also be used as a type of preventer treatment for asthma. These medications work by blocking the action of leukotrienes, which are chemicals in the body that cause inflammation and narrowing of the airways. While not in inhaler form, leukotriene inhibitors can be an effective option for some asthma patients.


Immunomodulators, such as omalizumab, are a newer type of asthma medication that works by targeting specific antibodies involved in the immune response that triggers asthma symptoms. These medications are typically used in severe cases of asthma that do not respond well to other treatments. Immunomodulators are usually given via injection rather than inhalation.

It’s important for asthma patients to work closely with their healthcare provider to determine the most appropriate type of preventer inhaler based on their individual asthma symptoms and severity. Regular monitoring and adjustment of medication are key to effectively managing asthma and minimizing the risk of exacerbations.

Flavored Inhalers and Asthma

Flavored inhalers have gained popularity in recent years, particularly among pediatric asthma patients. The enticing flavors of these inhalers, such as cherry, strawberry, and mint, aim to make the inhaler experience more pleasant for individuals, especially children, who may otherwise find it challenging to use their asthma inhalers regularly.
