What is an Inhaler?
An inhaler is a handheld device used to deliver medication directly into the lungs. Inhalers are commonly used to treat asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions. If you have been prescribed an inhaler, it's important to know how to use it correctly to ensure that you receive the maximum benefit from the medication. Here's what you need to know about inhalers and how to use them properly.

What are the Different Types of Inhalers?
Inhalers are medical devices used to deliver medication directly to the lungs to treat various respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other pulmonary disorders. These conditions often require medications such as bronchodilators, corticosteroids, or a combination of both, and inhalers are an effective way to deliver these medications directly to the airway, where they can act quickly.
There are several types of inhalers, each designed to suit the needs of different patients and their conditions. The main types of inhalers include metered-dose inhalers (MDIs), dry powder inhalers (DPIs), soft mist inhalers (SMIs), and nebulizers.
1.) Metered-dose inhalers (MDIs)
Metered-dose inhalers (MDIs) are one of the most common types of inhalers and are widely used for delivering a precise dose of medication in the form of an aerosol. MDIs consist of a pressurized canister that contains the medication, which is released as a fine mist when the inhaler is activated. When a person inhales, the aerosolized medication is delivered directly to the lungs.
MDIs are typically used to deliver both bronchodilators, such as albuterol, and inhaled corticosteroids, such as fluticasone. One of the key features of an MDI is the metering valve, which ensures a consistent and accurate dose each time the inhaler is used.
While MDIs are effective, they require proper technique for optimal use. It is essential to coordinate pressing the inhaler with inhaling deeply. This can be difficult for young children, the elderly, or those with manual dexterity issues. For this reason, spacers or holding chambers are often used with MDIs to make inhalation easier and more effective.
2.) Dry Powder Inhalers (DPIs)
Dry powder inhalers (DPIs) are another common type of inhaler, but instead of delivering medication in an aerosolized mist, DPIs release medication in a fine, dry powder form. DPIs rely on the patient’s own inhalation to draw the powder into the lungs, making them different from MDIs that are powered by a propellant.
DPIs have several advantages over MDIs, including the fact that they do not require the use of a propellant, so they are more environmentally friendly. Additionally, DPIs are easier to use for some people because they do not require the coordination of pressing a canister and inhaling at the same time. However, DPIs require a strong and fast inhalation to properly deliver the medication, which can be difficult for young children, the elderly, or individuals with weakened respiratory muscles.
There are various types of DPIs available, including the Diskus, Turbuhaler, and HandiHaler, which differ in design and how the medication is loaded into the device. Each device delivers a specific dosage of medication with each inhalation.
3.) Soft Mist Inhalers (SMIs)
Soft mist inhalers (SMIs) are a newer type of inhaler that create a slow-moving mist of medication, which is easier to inhale than the fast-moving aerosol produced by MDIs. This slower mist allows the medication to be more effectively deposited in the lungs, especially in the smaller airways. SMIs are often used for patients with conditions like COPD, where deep lung penetration of the medication is important.
One of the main advantages of soft mist inhalers is that they do not require coordination between pressing the device and inhaling, which makes them easier to use for individuals who have difficulty with the technique required for MDIs. SMIs are also more forgiving in terms of the inhalation speed. The slow-moving mist allows for better medication absorption and can reduce the risk of medication wastage.
A commonly used soft mist inhaler is the Respimat, which delivers medications like tiotropium (a long-acting bronchodilator) and combination medications used to treat COPD.
4.) Nebulizers
A nebulizer is a device that turns liquid medication into a mist, which can then be inhaled directly into the lungs. Unlike other types of inhalers, nebulizers are powered by electricity, a battery, or a compressed air system, and they provide a continuous flow of medication over a longer period of time, typically 10 to 15 minutes. Nebulizers are usually used for individuals who may have difficulty using MDIs or DPIs due to age, illness, or physical limitations, such as young children or elderly patients.
Nebulizers are commonly used to treat conditions like asthma, COPD, and cystic fibrosis. They can deliver both short-acting and long-acting medications, including bronchodilators and steroids, in a form that is easy to inhale. The continuous mist allows patients to take in larger doses of medication without needing to take multiple puffs as they would with an MDI or DPI.
Although nebulizers are effective, they are generally less portable than other inhalers, as they require a power source and can be bulky. This limits their convenience compared to MDIs or DPIs, which are more compact and can be used anywhere. Nonetheless, nebulizers remain an essential treatment option for patients with severe or chronic respiratory conditions who require frequent or high doses of medication.
The type of inhaler used will depend on the patient's condition, age, and preference. Some inhalers are more effective for certain conditions, while others may be easier to use or better tolerated by some patients. Patients need to work closely with their healthcare provider to determine the best inhaler for their individual needs.
How to Use an Inhaler?
Regardless of the type of inhaler you are using, the following steps can help ensure that you use it correctly:
1. Remove the cap from the inhaler.
2. Shake the inhaler vigorously for a few seconds to ensure that the medication is mixed properly.
3. Exhale completely to empty your lungs.
4. Hold the inhaler upright, with the mouthpiece pointing toward you and away from your face.
5. Seal your lips tightly around the mouthpiece to create a tight seal.
6. As you begin to breathe in slowly and deeply, press down on the inhaler to release the medication. It's important to breathe in slowly and deeply to ensure the medication reaches the lungs.
7. Hold your breath for 5-10 seconds to allow the medication to reach the lungs.
8. Exhale slowly and completely.
9. Wait for 30-60 seconds before repeating the process, if you need another dose.
It's important to note that the specific instructions for using an inhaler may vary depending on the type of inhaler you have, so it's important to read the instructions carefully and ask your healthcare provider if you have any questions.
Inhaler Maintenance
Proper inhaler maintenance is important to ensure that your inhaler works properly and delivers the medication effectively. Here are a few tips for inhaler maintenance:
1.) Clean your inhaler regularly with a dry cloth or tissue.
2.) Avoid getting your inhaler wet, as moisture can damage the medication and the device.
3.) Check the medication level in your inhaler regularly, and replace it as needed.
4.) Keep your inhaler in a dry, cool place, away from direct sunlight and heat.
If you have difficulty using an Inhaler, ask your doctor/Healthcare provider for a Spacer.(alert-success)
