How Your COPD Inhaler Helps You Manage Your Symptoms & Control Your Disease

May 25, 2020 9:13:00 AM / by Devon Slavens

How Your COPD Inhaler Helps You Manage Your Symptoms & Control Your Disease

Inhaled medications form the backbone of COPD treatment, and they're vital tools for keeping the respiratory symptoms of COPD under control. If you're like most people with COPD, you probably have at least one inhaler to help you manage your symptoms at home.

 

COPD inhalers come in many different shapes, sizes, and brands, each with their own unique dosages and medicine combinations. Most of these inhalers fall into one of three main types: maintenance inhalers (for daily use), rescue inhalers (for as-needed use), and steroid inhalers (for reducing exacerbations).

 

Many people with COPD use more than one type of inhaler, especially those whose symptoms are continuous and at least moderate in severity. In fact, typical treatment for the more advanced stages of COPD includes a daily maintenance inhaler, for baseline symptom control, and a rescue inhaler for quick relief when symptoms get worse.

 

But despite the fact that these medications are such an integral part of COPD treatment, many patients who use inhaled medications don't really understand how important they are or even how they work. That's why we've created this guide to tell you all about COPD inhalers, including how they affect your lungs and how they help your manage your disease.

 

In this post, we're going to go over the two main types of inhalers used to treat COPD—maintenance inhalers and rescue inhalers—to explain what they do, how they differ, and how they fit into COPD treatment as a whole. We'll also explain how these medications actually work inside your body that makes it easier to breathe.

 

If you or someone you love has COPD, it's worth taking the time to learn as much as you can about these key COPD medications, even if you're not taking them yet. After all, knowing what to expect can make it easier to adjust as your COPD symptoms, prescriptions, and COPD treatment needs inevitably change over time.

 

Learning about your medications and familiarizing yourself with these treatments can even help you use your medications more effectively and be more pro-active about managing your disease. The more knowledge you have, the easier it will be follow your COPD treatment plan, understand your medication instructions, and avoid common medication mistakes.

Because COPD has no real cure, the main purpose of most COPD medications—including COPD inhalers—is symptom management. That is, COPD medications can be used to reduce, delay, or prevent the negative symptoms (especially respiratory symptoms) caused by COPD, even if they can't fully stop or get rid of the disease

 

As we mentioned before, there are three main types of COPD inhalers, and each uses a different type of medication or combination of medications. Each medication is designed to target specific biological processes in the lungs and airways, and how they alter those processes determines their specific therapeutic effect.

 

These are the three main categories of COPD inhalers:

  • Rescue inhalers use short-acting bronchodilators, a type of medication that works very quickly to relax and open up your airways.
  • Maintenance inhalers use medications known as long-acting bronchodilators, which also relax your airways but have subtler, longer-lasting effects.
  • Steroid inhalers contain corticosteroid medications, which target the body's immune system to suppress inflammation in the lungs. These are mainly prescribed to reduce COPD exacerbations, and we discuss them in more detail in a separate guide.

 

As you can see, each type of inhaler plays a unique role in COPD treatment, which is why many patients need to use a combination of two or more types of inhalers to keep their symptoms in check. The most commonly used are the two types of bronchodilator medications, which are widely prescribed as a mainstay of treatment for people with moderate to severe COPD.

 

It's also important to note that some people with COPD use steroid combination inhalers, which contain both a corticosteroid medication and a long-acting bronchodilator. If you're interested in learning more about steroid inhalers, you can check out our guide on steroid medications and how they are used to treat COPD.

 

 

What Are Bronchodilator Inhalers?

The focus of this guide is bronchodilator inhalers, which include both rescue inhalers and maintenance inhalers. Both of these medications have similar effects on the lungs and play vital roles in the everyday management of COPD symptoms.

 

Both short-acting and long-acting bronchodilators help your airways open up wider by forcing the smooth muscles that surround your airways to relax. This effect is known as bronchodilation and it makes it easier to breathe by improving airflow to and from the lungs.

 

The “broncho” part of the word bronchodilation refers to the bronchial tubes, which are the main, large airways that carry air to and from the lungs. “Dilation” simply means to make something—in this case, the bronchial tubes—wider, larger, or more open.

 

Bronchodilation is the opposite of bronchoconstriction, which happens when the smooth muscle surrounding the airways contracts, squeezing the airways down tight and reducing the size of the space inside. Bronchoconstriction is a major cause of breathing problems in people with COPD, and it's what bronchodilator medications are mainly designed to correct.

 

There are two main types of bronchodilator medications: beta-2 agonists and anticholinergics, both of which come in both short-acting and long-acting varieties. Many COPD inhalers contain only one type of bronchodilator (a beta-2 agonist or an anticholinergic), while others use a combination of both.

 

We'll discuss these bronchodilator inhalers in more detail in just a bit, but first you need to understand why people with COPD have problems with bronchoconstriction in the first place. That's why, in this next section, we're going to give you a brief explanation of how COPD triggers the chronic bronchoconstriction that COPD inhalers are meant to relieve.

 

Of course, COPD is a complex disease, and there are many complex factors contributing to COPD symptoms that are beyond the scope of this guide. However, a general knowledge of how airway inflammation and constriction happen is vital for understanding how bronchodilator inhalers work

 

If you've learned about these topics already (perhaps from other guides in our Respiratory Resource Center), feel free to skip ahead to the section “How Bronchodilators Work in the Body to Make it Easier to Breathe.”

 

 

Airway Inflammation & Bronchoconstriction: Major Causes of Breathing Problems in People with COPD

You might already know that COPD affects not only your lungs, but also your airways, including the large bronchial tubes that carry the air to and from your lungs when you breathe. COPD causes your airways to be frequently—if not continuously—inflamed, which is one of the main causes of COPD symptoms, especially those associated with chronic bronchitis.

 

Bronchoconstriction is, in part, the body's reaction to this inflammation, and one of the major reasons for restricted airflow and shortness of breath in people with COPD. Inflammation also triggers the airways to produce more mucus than usual, which causes congestion in the airways that restricts even more air from flowing through.

 

This extra mucus is especially problematic when the airways are already constricted, because it makes it more difficult to remove the mucus from the lungs. Instead of allowing the mucus to move up and out of the airways (which is the main purpose of coughing and other mucus clearance techniques), bronchoconstriction causes the mucus to get stuck inside the narrow airspace, creating a particularly stubborn source of obstruction.

 

In this way, airway constriction is one of the main reasons why people with COPD experience symptoms like coughing and shortness of breath, which are the defining symptoms of the disease. The excess mucus and airway inflammation triggers the need to cough, while the bronchoconstriction and mucus obstruction makes it more difficult to breathe.

 

Additionally, it takes extra energy to breathe air through narrowed and obstructed airways, which wears out the muscles in your chest that you use to breathe. This breathing muscle exhaustion, in addition to bronchoconstriction, also makes it more difficult to empty your lungs completely when you exhale.

 

The air that you cannot push out stays trapped inside the lungs, preventing them from collapsing all the way. The stale air also takes up valuable space that's needed for the fresh, oxygen-rich air that you take in when you inhale.

 

This, in addition to other damage caused by inflammation, can eventually cause irreparable damage to the lungs, including a complication known as lung hyperinflation. This occurs when the lung tissue loses its elasticity, becoming too stiff to expand and collapse fully when you breathe; this essentially “stretches out” and enlarges the lungs, causing even more air trapping and making it more difficult to breathe.

 

All of these effects, which are largely a consequence of bronchoconstriction, are a major cause of shortness of breath and general breathing difficulties in people with COPD. Because of this, many COPD medications—including bronchodilators—are designed specifically to reduce bronchoconstriction.

 

In the next section we'll build on these concepts—particularly bronchoconstriction—to explain how bronchodilators work in your respiratory system to make it easier to breathe. Then, we'll discuss how long-acting and short-acting bronchodilators are used to treat COPD, including what they're prescribed for, why they're effective, and what you should know about their benefits and risks.

 

 

How Bronchodilators Work in the Body to Make it Easier to Breathe

As we've mentioned already, all bronchodilators have a similar effect, which is to “open up” or widen the space inside the airways. This reduces airway obstruction and allows air to flow through more freely, making it both easier to breathe and easier to move mucus up through the airways and out of the lungs.

 

This is the main way in which bronchodilators reduce shortness of breath, but they can also help mitigate other long-term complications related to airway constriction. This includes things like breathing muscle fatigue, air trapping, and lung hyperinflation.

 

However, the question of how bronchodilator medications are able to relieve airway constriction through biological mechanisms is a bit more complex. This is further complicated by the fact that there are three main classes of bronchodilator medications: beta-2 agonists, anticholinergics, and methylxanthines.

 

Beta-2 agonists and anticholinergics are the most widely used bronchodilators, while methylxanthines (such as theophylline) are sometimes also prescribed. However, the use of methylxanthines to treat COPD symptoms is somewhat controversial, partially due to their high toxicity and partially due to a lack of research and understanding of their effects.

 

Because of this, we're going to limit our discussion here to the two main types of bronchodilator medications: beta-2 agonists and anticholinergics. Both classes of medication work by reducing airway constriction, but they differ significantly in how they achieve this effect.

 

 

Beta-2 Agonists Bronchodilator Medications

The first major type of bronchodilator is a class of drugs known as beta-2 agonists. These medications work by activating a specific type of receptor, known as a beta-2-adrenoreceptor (or beta-2 receptor, for short), which is found in the airway tissues as well as other parts of the body.

 

This receptor has the ability to affect the smooth muscles in the airways; these are the same muscles that contract in response to inflammation, causing airway constriction in people with COPD. When the beta-2 receptor gets activated, it stops those smooth muscles from contracting, forcing them to relax, resulting in bronchodilation that opens up the airways and makes it easier to breathe.

 

Taking a beta-2 agonist medication via an inhaler or nebulizer delivers the medication directly to your lungs and airways, where it absorbs into the cells lining the insides of your airway walls. Once inside, they can activate the beta-2 receptors in those cells, triggering airway muscle relaxation.

 

However, not all of the beta-2 agonist medication stays in the lungs; some of it inevitably gets absorbed into your bloodstream as well. The bloodstream carries the drug to beta-2 receptors located in other parts of body (e.g. the smooth muscle of the heart and blood vessels); this can trigger unwanted side effects like an increased heart rate and blood vessel dilation.

 

If you use a short-acting beta-2 agonist, this relaxation happens very quickly, providing almost instant relief from shortness of breath. Long-acting beta-2 agonists, however, work much more slowly, taking several hours to begin working, and often taking days to provide noticeable symptom relief after you first start taking the medication.

 

 

Anticholinergic Bronchodilator Medications

Anticholinergics work by blocking muscarinic receptors in cells. A muscarinic receptor is pictured above. (Image from Takuma-sa.)

 

 

Anticholinergics (also known as muscarinic antagonists) are a second type of bronchodilator medication that are used in COPD treatment. It's common for anticholinergics to be combined with a beta-2 agonist in a single inhaler.

 

Unlike beta-2 agonists, which relieve airway constriction by triggering airway muscles to relax, anticholinergics help prevent airway constriction by inhibiting a certain signal that triggers bronchoconstriction.

 

This “certain signal” is produced by an important type of receptor—known as a muscarinic receptor—which is found in cells all over the body, including the lungs and airways. These receptors are responsible for triggering the parasympathetic nervous system response, which affects different parts of the body in different ways.

 

In the lungs and airways, the parasympathetic response does two main things, both of which make it more difficult to breathe. First, it triggers the airway tissues to secrete more mucus (causing obstruction), and second, it triggers the airway muscles to contract (causing bronchoconstriction).

 

Here's where anticholinergics come in; these medications work by blocking muscarinic receptors in your lungs and airways, essentially rendering them inactive. This prevents the parasympathetic response from getting triggered in the first place, thereby preventing the airway narrowing and mucus obstruction it causes.

 

Just like beta-2 agonists (and other inhaled medications), a small amount of the anticholinergics you breath in will get absorbed into your bloodstream, even though most of it gets absorbed in the lungs. This leads to some muscarinic receptor activation in other parts of the body, which can cause negative side effects like constipation, confusion, and an irregular heartbeat.

There are several types of both short-acting and long-acting antocholinergics, which are used in short-acting and long-acting bronchodilators respectively. The quicker-acting versions work for up to 6 hours, while longer-acting anticholinergics can work for more than 24 hours.

 

 

Bronchodilators in COPD Treatment

 

 

Long-Acting Bronchodilators: Long-Term Symptom Relief

The purpose of long-acting bronchodilator inhalers in COPD treatment is to provide long-term relief from persistent COPD symptoms, particularly shortness of breath. They're considered a cornerstone of COPD treatment, and they're one of the most frequently-prescribed medications to treat COPD.

 

Long-acting bronchodilators are often referred to as “maintenance inhalers” because they help control the “stable,” everyday symptoms of COPD. This helps to reduce and stabilize symptoms, and helps prevent them from flaring up, which are some of the primary goals that doctors and people with COPD strive for with long-term disease maintenance.

 

Long-acting bronchodilators take a while after you start taking them (up to several days or weeks) to reach full effect, but they continue working for a long time (about 12-24 hours) once they do. This makes them essentially useless for immediate symptom relief, but extremely effective for sustained, long-term COPD symptom control.

 

 

Long-Acting Bronchodilator Therapy in COPD Treatment

Some people begin long-acting bronchodilator therapy as soon as the get diagnosed with COPD, but not everyone does. Some people who get diagnosed in the early stages of the disease don't require long-term treatment (or sometimes any treatment, yet) because their symptoms are still very mild or infrequent.

 

However, almost everyone who has COPD will need a long-term maintenance treatment eventually. As the disease progresses and COPD symptoms become more frequent, more persistent, and more severe, many patients need long-acting bronchodilators to keep their symptoms under control.

 

Most of the time, if you're prescribed a long-acting bronchodilator inhaler, you will need to use it once or twice a day, every day. Because long-acting bronchodilators take so long to work, it's vital to take them consistently so they can stay active in your body throughout the day.

 

This is why it's important to use your maintenance inhaler on a regular schedule; it ensures that the medicine works constantly and reliably to keep your symptoms suppressed. Try to avoid skipping or delaying your daily inhaler doses and do your best to follow the treatment plan precisely.

Unfortunately, some people mistakenly believe that they only need to use their maintenance inhaler when they're actively experiencing symptoms. This misconception leads them to use their inhaler inconsistently, or to stop using their inhaler altogether when their COPD symptoms improve.

 

However, this can be very dangerous; it can increase your risk for exacerbations, cause your symptoms to rebound, and make it more difficult to control your COPD symptoms in the long run. That's why, if your doctor prescribes you a daily maintenance inhaler, you need to follow his instructions exactly, and never stop taking your medication unless your doctor says it's okay.

Short-Acting Bronchodilators: Short-Term Symptom Relief

Short-acting bronchodilators (also known as “quick-relief inhalers” or “rescue inhalers”) are important in COPD treatment because they can provide immediate, short-term relief from COPD symptoms. Just like maintenance inhalers, quick relief inhalers work by relaxing airway muscles to reduce airway obstruction and make it easier to breathe.

 

However, unlike long-acting bronchodilators, which take hours to work and require regular, scheduled doses, short-acting bronchodilators can be used as-needed throughout the day. That's because they work almost immediately (within seconds or minutes) and their effects usually wear off within just a few hours after use.

 

The quick-yet-temporary nature of short-acting bronchodilators makes them ideal for treating incidental COPD symptom flare-ups, such as the temporary bouts of increased breathlessness that most people with COPD experience occasionally, if not often. At the same time, rescue inhalers are not effective for long-term symptom management due to the short length of their effects.

 

 

How Short-Acting Bronchodilators are Used in COPD Treatment

 

 

asthma-1147735_1280

 

Short-acting bronchodilators are often prescribed along with long-acting bronchodilators in a kind of dual therapy that works like this: The long-acting bronchodilator manages the baseline symptoms of COPD, reducing the risk of exacerbations and offering stable, long-term symptom relief. The short-acting bronchodilator is used for additional symptom relief, particularly for stopping sudden symptom flare-ups that inevitably occur.

 

However, some people with COPD are only prescribed short-acting bronchodilators and use them as the primary means to manage their symptoms.

 

This is most common in the early stages of the disease, when many patients only experience intermittent symptoms and thus don't need long-term symptom control. At this stage, COPD symptoms can sometimes be adequately spot-treated with quick-acting rescue inhalers whenever they occur.

 

Rescue inhalers are very effective at stopping sudden, severe symptom flare-ups, which can show up without warning and even be life-threatening in some situations. Because of this, if you've been prescribed a quick-relief inhaler, you should do your best to take it with you everywhere you go.

 

But though some flare-ups happen unpredictably without an obvious cause, many symptom flare-ups are at least somewhat predictable. For example, it's common to experience sharp increases in breathlessness during physical exertion or after breathing in lung irritants like allergens and smoke; when this happens, you'll definitely want to have your rescue inhaler nearby.

 

Most of the time, rescue inhalers are meant to be used during a symptom flare, especially ones that won't go away on their own. This can be particularly helpful when usual coping techniques—such as stopping to rest and using breathing techniques like pursed lips breathing—aren't enough to bring your symptoms under control.

 

 

girl-1906405_1280
Quick-relief inhalers can help relieve shortness of breath during exercise and other physical activities.

 

 

Some doctors even advise their COPD patients to use their quick-relief inhaler before beginning difficult activities (such as exercise) that tend to make their COPD symptoms worse. This can help if you experience recurrent bouts of persistent shortness of breath that interfere with your ability to do normal daily activities, such as showering, cooking, or doing other chores around the house.

 

In some cases, doctors advise COPD patients to use their quick-relief inhaler right before beginning certain COPD treatments hat rely on good airflow to work, such as performing mucus clearance techniques. Opening up your airways can make these types of treatments more effective; for instance, by allowing you to cough up more mucus since widened airways allow mucus to move through more freely.

 

This is the same reason why many doctors advise COPD patients to use their quick-acting inhaler before they take their other inhaled medications, such as their daily, long-acting maintenance inhaler. The improved airflow can make it easier to inhale the full dose of medication, and can help more of the medication actually make it into your lungs.

 

However, rescue inhaler use can vary significantly from person to person; some patients might need to use it a couple times a week, while others need to use it multiple times a day. Some patients benefit from using their rescue inhaler on a regular schedule every day.

Doctors' instructions for when, how often, and under what circumstances you should use your rescue inhaler can vary significantly, and depend on a lot of different factors. This is why, if your doctor has prescribed you a rescue inhaler, you need to make sure you fully understand how your doctor wants you to use it.

 

Some patients are advised to use their rescue inhaler only when absolutely needed, such as during emergencies or times when they're unable to control their symptoms in any other way. Other patients are encouraged to use their rescue inhalers more frequently, or benefit from using their rescue inhaler during specific activities or at certain times of day.

 

Still, knowing precisely when you should use your quick relief inhaler can still get confusing, which is why you shouldn't be afraid to ask questions or call your doctor for advice. Ask your doctor to write down (or print) clear and detailed instructions that you can take home.

 

Things you should know about using your rescue inhaler:

  • The correct steps to use your inhaler (this might includes things like shaking, priming, dose counting, etc. that vary between different types of inhalers)
  • When, and under what circumstances, you are supposed to use your quick-relief inhaler
  • How long you should wait between doses
  • The maximum number of doses is that you can take in a day
  • What side-effects to look out for, and when you should call your doctor about a new side effect
  • What to do if you start needing to use your rescue inhaler more often than usual (this could signal an oncoming COPD exacerbation or indicate that your treatment plan needs adjustment)

 

All of these things can vary based on a many factors, including the type of short-acting bronchodilator you use, the dosage your doctor prescribes, and your individual health needs. So you always have a quick reference on hand, make sure your doctor includes rescue inhaler instructions in your COPD action plan.

The Benefits & Risks of Bronchodilator Inhalers for People with COPD

 

 

As mainstays of COPD treatment, both short-acting and long-acting bronchodilators have received a great deal of attention in COPD research. Many studies have looked at the benefits and risks of these medications in different aspects of COPD treatment, and have found them to be some of the most effective pharmaceutical treatments for relieving breathing symptoms in people with COPD.

 

 

Long-Acting Bronchodilator Benefits

 

 

competition-1019774_1280
Long-acting bronchodilators can improve your ability to exercise.

 

 

There is a large body of research showing that long-acting bronchodilators are both effective and reliable treatment for COPD. Their main benefits include general, long-term breathing symptom relief, including including better airflow, reduced mucus production, and reduced shortness of breath.

 

These benefits extend to many other COPD symptoms—particularly those associated with bronchoconstriction—including lung hyperinflation and mucus build-up in the airways. Long-acting bronchodilators also help to reduce breathlessness during during physical activity, which makes it easier to exercise and do other daily activities that require physical exertion (e.g. chores around the house).

 

There is also a “significant body of evidence” showing that long-acting bronchodilators can reduce your risk for developing COPD exacerbations. Alone, they can reduce exacerbations rates by about 20 percent in people with moderate to severe COPD, and up to 30 percent when combined with an inhaled corticosteroid medication.

 

Some studies suggest that inhalers combining both long-acting beta-2 agonists and anticholinergics are more effective at controlling COPD symptoms than either one of them on their own. However, which type of long-acting bronchodilator therapy is best for a specific patient depends on individual factors like symptom severity and how well they happen to respond to different medications.

 

Overall, long-acting bronchodilators have wide-reaching and long-lasting benefits that can improve your ability to breathe and function in everyday life. This is why they remain a key component of treatment for a large number of people with COPD.

 

 

Short-Acting Bronchodilator Benefits

Short acting bronchodilators offer many of the same benefits for symptom relief that short-acting bronchodilators do, just on a much shorter time scale. They offer immediate benefits, as opposed to long-term ones, since their effects wear off just a few hours after use.

 

Here are some of the short-term benefits of rescue inhalers for people with COPD:

  • Reduced shortness of breath
  • Improved ability to cough up mucus from the lungs
  • Improved delivery of other inhaled medications to the lungs

 

Short-acting bronchodilators also tend to have stronger effects, which allows them to relieve the inevitable symptom flare ups that the slow and steady action of long-acting bronchodilators can't stop. This allows them to offer immediate relief from COPD symptoms, even during severe bouts of coughing and shortness of breath.

 

However, some research suggests that short-acting bronchodilators might also offer a small amount of lasting symptom relief. One study, for instance, found that COPD patients who used a short-acting bronchodilator regularly every day had slightly increased lung function and reduced daily breathlessness scores.

 

Unfortunately, studies on the benefits of short-acting bronchodilators in COPD treatment specifically are lacking, though there is a great deal of research supporting the effectiveness of quick-relief inhalers for asthma. Nevertheless, when a treatment works, it works, and short-acting bronchodilators have long been recommended by experts (PDF link) for both regular and as-needed COPD symptom relief.

 

 

Side-Effects of Bronchodilator Medications

 

 

Because beta-2 agonists and anticholinergics work via different mechanisms, the potential side-effects of using your bronchodilator inhaler depend on what kind of medication you are using. However, there tends to be little difference in side effects between short-acting and long-acting bronchodilators from the same medication class, (e.g. both short-acting anticholinergics and long-acting anticholinergics tend to have similar side effects), though short-acting medications are more likely to have temporary, rather than lasting, side effects.

Conclusion

 

COPD medications are more than just helpful tools, they are the lifelines that millions of people with the disease depend on to keep them alive and keep them going every day. If you have COPD, it's vital to make sure you understand of all your medications, and especially the inhalers that you use to control your symptoms every day

 

Having this knowledge can help you communicate better with your doctor, and could even help you learn to better manage your disease. The more familiar you become with your COPD medications, the easier it will be to take your medications correctly and follow your COPD treatment plan.

 

What's more, learning more about your medications and what they do for you can help you better appreciate why they're important for your health. Who knows, it might even motivate you to be more diligent about your medication routine.
