Inhalers are mostly used by asthmatic patients to relieve the milder symptomatic and control the disease in the long run. One of the great diversities is that although inhalers are used for asthma, there are many different types available because people often have distinct preferences, feature requirements, and specifications in terms of ease of use. These types range from simple puffs to computerized works.
Asthma inhalers are classified into two major groups: relievers and controllers. Reliever inhalers manage the immediate symptoms of asthma and provide a short-term response. In contrast, the controller inhalers gradually but steadily build up the medication's effect over time and help in long-term asthma management. Of the different asthma inhaler varieties available, below is a closer look at the various kinds of asthma inhalers.
MDIs are inhalers that release a pre-measured drug dose as a mist. Most people will find MDIs very convenient and self-explanatory because most of them are designed to work with a spacer that helps deliver the drug into the lungs by getting rid of the need to coordinate the triggering of the inhaler with the breathing.
DPIs are breath-activated inhalers. Unlike MDIs, which require the drug to be released from the inhaler, DPIs deliver powdered medication that the patient must inhale or breathe in. This type of inhaler does not have to be primed or pushed to release the drug, making it more straightforward than using MDI for patients, especially the elderly.
Autohalers are inhalers that are not operated by hand; they are MDIs that release the dose only when the patient inhales. This feature adds convenience for those who find it difficult to coordinate their breath with the medication, such as young children or elderly adults. Numerous Autohaler models contain a moisture indicator that informs patients when the device is near running out of medication.
This inhaler uses a soft mist rather than an aerosol to deliver the medication. The device is turned to release medication, which is then inhaled deeply. The mist stays active longer than an aerosol, allowing for better medication absorption into the lungs. Many patients consider the Respimat inhalers easier to use than the other inhaler types.
These are not classed as inhalers, although they perform the same function as inhalers, which is to deliver drugs. Nebulizers work best for individuals who cannot coordinate an inhaler or are having a severe asthma attack. The inhalers are mainly used in clinics, but larger home versions can also be used.
An asthma inhaler uses different medicine types, depending on the severity of the patient's illness, the kind of inhaler used, and the doctor's recommendation. Below is an inventory of the most typical drugs classified according to the inhaler types, with a brief description of their composition and the nature of the disease they are meant to treat.
A composition or combination inhaler contains multiple medications: a corticosteroid, which reduces inflammation, and a long-acting beta-agonist (LABA), which dilates the airways. Commonly used drugs include Fluticasone/Salmeterol and Budesonide/Formoterol.
Corticosteroid inhalers deliver drugs that lessen airway irritation. Corticosteroids are recommended for long-term control of asthma. Other corticosteroid examples include Beclomethasone, Budesonide, and mometasone.
Inhalers posted as fast relief of acute asthma symptoms contain bronchodilators, which help dilate the airways. Short-acting beta-agonists (SABAs) are the most common bronchodilators. Salbutamol and Albuterol are the most popular Bronchodilators available in the market. Both offer fast relief from asthma symptoms. Terbutaline is another bronchodilator.
Inhalers containing leukotriene modifiers work by blocking leukotrienes, which are chemicals in the body that constrict the airways. These inhalers help in controlling asthma by reducing swelling and narrowing the airways. Montelukast is a typical leukotriene receptor antagonist.
Inhalers used to deliver Theophylline, an anti-asthmatic drug that relaxes and opens the airways, are less frequently used due to safety issues and the widespread availability of newer inhaler medications. However, some chronic asthma patients still use Theophylline due to their long-acting properties.
The commercial worth of asthma concentrators can be understood by looking at several factors, such as market growth, the accessibility of inhaled drugs, the need for improved respiratory medications, and the rising pervasiveness of asthma.
As indicated by the statistics, the value of the global market and the increasing number of patients indicate the increasing worth. Currently, the global inhaler market is valued in billions, with expectations of continued growth due to factors such as the launch of new and effective inhalers, increasing awareness about the appropriate treatment of asthma, and the development of the inhaler technology.
In recent years, there have been numerous attempts to increase access to asthma inhalers worldwide, adding to the possibilities for commercial gain in the medication market. The World Health Organization (WHO) and various other local and international organizations try to avoid and manage asthma through different initiatives.
As a result, Asthma inhalers are becoming increasingly available to many people. The growing interest in inhaled drugs creates high demand and, consequently, an opportunity for the pharmaceutical industries to develop new inhalers. In addition, the development of consumer and out-of-pocket health insurance plans drives demand for asthma inhalers, hence, their increasing commercial value.
According to studies done, the annual healthcare expenses for a person with asthma who uses an inhaler is about $7000. This typically increases, especially in people suffering from chronic or severe asthma. This demonstrates how important asthma inhalers are in reducing the costs associated with asthma treatment and achieving good control over the condition.
Maintaining asthma inhalers in good condition is essential because their performance directly affects the patient's well-being. Therefore, it is important to regularly check for possible damages, leaks, or blockages in the inhalers and ensure the medications are within the recommended range. In addition, squiring the right techniques in using and cleaning inhalers helps improve effectiveness and prolong their lifespan.
Good quality inhalers are also key to successful asthma management. Patients need medications made under rigorous quality control standards to ensure safe, effective, and consistent drug delivery. Therefore, using only inhalers from certified health facilities is important.
Also, inhaler devices must be handled gently to keep them free of damages. For example, medication delivery systems like spacers or nebulizers should be checked constantly for cracks or abnormalities. Inhalers should be kept in dry and low-heat places, as moisture can cause the medication to clump up and the device, in general, to become dysfunctional.
Cleaning inhalers helps reduce medication build-up, which can cause the inhaler to malfunction. For example, most manufacturers recommend cleaning the device at least once a week with a dry cloth or rinsing under water, depending on the kind of inhaler. It only washes or dries after it has been fully cleaned and dried and ready for use without residues obstructing the airway.
With some inhalers, like MDIs and spacers, it's important to inspect the spacer for dampness where medication might have clumped and bonded together, then released upon inhalation. The inhaler should be examined on a regular basis to see if there are any signs of damage. It is also quite important to check the drug levels in the inhaler, as using inhalers with low drug levels can be futile. Most inhalers have drug indicators that inform the user when it's time to get a new one.
When selecting the right asthma inhaler, the following factors should be considered.
Type of inhaler
As mentioned, asthma inhalers are divided into the reliever, controller, and combination types. The choice then boils down to the prescription that has to be filled because it is the physician who makes the choice of the appropriate inhaler for the patient's needs.
Ease of use
The other important thing to consider is how easy an inhaler is to handle, particularly for the group of patients that are children and older adults. While some have features that make them easy to use, others, like MDIs and DPIs, require a spacer or will need the patient to be more coordinated.
Efficacy
This strictly means how effective the inhaler is in delivering the required medication. Some inhalers, like nebulizers and Respimat, significantly increase the amount of drug reaching the lungs than other inhalers. This point is highly crucial for patients with severe asthma or requiring larger drug doses or needs.
Cost
Cost is always a major concern, especially if the inhaler has to be purchased repeatedly. Some insurance covers asthma medications, but others do not. It is best to consult with a healthcare provider to determine which inhaler is more affordable and likely to be covered by the medical insurance.
Assess availability
Once the best choice of inhaler has been established, ensure it is available at local or online pharmacies. Availability means that certain manufacturers make or stop making certain inhaler models from time to time. Larger pharmaceutical companies may have shortages or discontinue the production of particular inhaler varieties and thus interfere with the ability to obtain the preferred inhaler.
A1: No, spacers should not be used with respimat inhalers since they are designed to work with metered-dose inhalers only. Spacers provide an additional time frame for inhalers to better deliver medication within the lungs. However, other inhalers like dry powder inhalers, nebulizers, and soft mist inhalers are not used with spacers.
A2: The number of puffs a person should take from an asthma inhaler depends on the specific inhaler and the person's needs. Some inhalers are prescribed to be used daily to maintain stable asthma, while others may be needed only occasionally when symptoms worsen.
A3: Asthma inhalers that contain corticosteroids are generally safe for most people with asthma. Inhaled corticosteroids are commonly used to control asthma symptoms and reduce inflammation within the airways. However, healthcare experts should be consulted to determine if the risk outweighs the benefits when using any medication.
A4: It varies per individual, but the general recommendation of spaers is to use them 2 to 3 times a week, not more than 4 times in a day. Overusing an inhaler means the medicine isn't being delivered properly, and the body is tolerating the drug, so it's important to avoid overusing the medication.
