Asthma and COPD treatments: Different inhaler options available
In the United States, over 25 million people are affected by long-term respiratory conditions such as asthma and COPD, including 5 million children under 18 years old. Fortunately, treatments are available to help manage these conditions, including inhalers and nebulizers.
Inhalers and Nebulizers: What's the Difference?
Inhalers come in various types, each with its advantages and disadvantages. A common type is the metered-dose inhaler (MDI), which contains medicine in aerosol form and requires the user to press the canister to activate the propellant and inhale at the same time. Another type is the nebulizer, which involves breathing through a mask and consists of an air compressor, a container of liquid medicine, and a tube that connects the two. Nebulizers are ideal for people who might not use an inhaler effectively, including young children.
Medicines for Asthma and COPD: Bronchodilators and Corticosteroids
The medical term for the medicines found in inhalers is bronchodilators. They relax the airway muscles, allowing them to open up so a person can breathe more easily. For asthma, corticosteroids are a type of medication used in inhalers that decrease inflammation in the airways and prevent asthma flare-ups. Long-acting beta-agonists (LABAs) help relax the muscles that line the lung’s airways and keep them open, making breathing easier. Common types of corticosteroids for asthma inhalers include beclomethasone, budesonide, ciclesonide, fluticasone, mometasone, and others.
For COPD, tiotropium bromide is a controller medicine that doctors often prescribe with other controller therapies. Anticholinergics are another type of long-term, controller medicine used in asthma inhalers that help reduce mucus production, relax the lung muscles, and widen the airways. Quick-acting beta-agonists, or quick-relief and rescue medicines, are used during an asthma flare-up to open the airways and relieve symptoms quickly.
Choosing the Right Inhaler: Factors to Consider
Selecting an inhaler requires balancing efficacy, patient capabilities and preferences, safety, and practical considerations. The goal is to maximize adherence, symptom control, and reduce exacerbations in asthma and COPD patients. Factors doctors should consider when prescribing an inhaler device include the patient’s ability to use the device correctly, disease severity and type, patient preference, onset of action and risk of exacerbations, safety concerns, cost and formulary availability, and environmental impact.
Advantages and Disadvantages of Inhaler Types
| Inhaler Type | Advantages | Disadvantages | |------------------------------|---------------------------------------------------------------|-------------------------------------------------------------| | Pressurized Metered-Dose Inhalers (pMDIs) | Fast onset of action; widely used; effective delivery if technique correct | Requires coordination of actuation and inhalation; some patients find technique difficult | | Dry Powder Inhalers (DPIs) | Breath-actuated, no need for coordination; may be more environmentally friendly | Require sufficient inspiratory flow, which some patients, especially with severe disease, may lack | | Soft Mist Inhalers (SMIs) | Deliver a slow-moving mist that's easier to inhale; less inspiratory effort needed | Usually more expensive; less widely available | | Capsule-based DPIs | Portable and straightforward dose loading | Capsule handling can be inconvenient; higher risk of improper use | | Single-use Capsule DPIs | Simplifies dose preparation | Can generate more waste; sometimes less preferred by patients |
Additional Considerations
- Clinical outcomes between device types may be comparable, but differences in exacerbation rates and symptom control can occur due to medication or device specifics.
- Patients with limited inspiratory capacity (common in severe COPD) may have difficulty using DPIs effectively and may benefit from pMDIs or soft mist inhalers.
- Convenience and ease of use, including priming requirements and dose preparation, affect adherence.
- Cost and environmental impact also play a role, with dry powder inhalers generally being less expensive and more environmentally sustainable.
