Bronchodilators and Rescue Inhalers: Short- and Long-Acting Types

What Are Bronchodilators?

Bronchodilators are medications that relax muscle bands that tighten around your airways. This opens the airway and lets more air move in and out of your lungs. That helps you breathe more easily. Bronchodilators also help remove mucus from your lungs. Open airways mean mucus can move more freely, too, and you can cough it up.

Almost all people with asthma use a bronchodilator to help open their airways.

Short-acting bronchodilators are used as a “quick relief” or “rescue inhalers”, while long-acting bronchodilators can be used every day to control asthma — along with an inhaled steroid.

What Are the Types of Bronchodilators for Asthma?

For treating asthma symptoms, there are three types of bronchodilators: beta-agonists, anticholinergics, and theophylline. You can get these bronchodilators as tablets, liquids, and shots, but the preferred way to take beta-agonists and anticholinergics is inhaling them.

What Are Short-Acting Bronchodilators?

Short-acting bronchodilators are called quick-acting, reliever, or rescue medications. You might hear them called rescue inhalers. These bronchodilators relieve acute asthma symptoms or attacks very quickly by opening your airways. The rescue inhalers are best for treating sudden asthma symptoms. The action of inhaled bronchodilators starts within minutes after you inhale them and lasts for 2 to 4 hours. Short-acting bronchodilators are also used before exercise to prevent exercise-induced asthma.

Short-acting bronchodilators can also be used in an asthma nebulizer in the form of a liquid to treat an asthma attack at home.

Overuse of short-acting bronchodilators, whether it’s a rescue inhaler, in tablets, or in liquid, is a sign of uncontrolled asthma that needs better treatment. If you need to use your short-acting bronchodilators more than twice a week, talk with your doctor about improving your asthma control therapy.

Short-acting bronchodilator inhalers available in the United States include:

What Are Long-Acting Bronchodilators for Asthma?

Long-acting bronchodilators are used to provide control — not quick relief — of asthma. They should only be used with inhaled steroids for long-term control of asthma symptoms. You’ll take a long-acting bronchodilator twice a day.

Long-Acting Asthma Inhalers Available in the United States Include:

• Advair, Dulera, and Symbicort (a combination of a long-acting beta-agonist bronchodilator and an inhaled steroid)
• Salmeterol (Serevent)
• Formoterol (Foradil)
• Formoterol solution for nebulizers (Perforomist)

• Long-acting beta-agonist bronchodilators raise the risk of death from asthma and should only be used as additional treatment for people who are using an inhaled steroid. For details, talk to your doctor and see the drugs’ black-box warning.

Are There Common Side Effects of Bronchodilators Used for Asthma?

Bronchodilators can have side effects such as:

How Do Anticholinergic Bronchodilators Work?

Anticholinergics are bronchodilators mainly used for treating COPD (chronic obstructive pulmonary disease, like emphysema) and asthma.

• Atrovent treats COPD and can be used off-label to treat asthma flares. You can get it as an inhaler and a nebulizer solution. Dry throat is the most common side effect. If the medication gets in your eyes, it can cause blurred vision for a short time.
• Revefenacin (Yupelri) is a new medication used daily to help those with COPD breathe easier. Long-acting, it is taken once a day with a nebulizer.
• Tiotropium bromide (Spiriva Respimat) is for people who have either asthma or COPD. It comes in an inhaler. Anyone over 6 can may use this medication once daily as a long-term asthma treatment. It’s used for COPD flares and long-term treatment if inhaled bronchodilators don’t help.

What Is Theophylline?

Theophylline is a relatively weak but inexpensive bronchodilator that has a chemical similar to caffeine. It relaxes the smooth muscle that surrounds your airways.

Theophylline is sold as a generic pill or under the brand names Theo-24 and Uniphyl. It’s available as an oral (pill and liquid) or intravenous (through the vein) drug. You can also get it in short- and long-acting forms to prevent asthma symptoms, especially nighttime symptoms. It’s not often used for asthma, though, because your doctor has to check your blood levels while you’re on it to make sure you aren’t getting too much.

What Are the Side Effects of Theophylline?

Side effects of theophylline include:

These side effects may also be a sign that you’ve taken too much medication. Your doctor will check levels of the drug in your blood to make sure you’re getting the proper amount.

Always tell your doctors if you take theophylline for asthma because certain medications, like some antibiotics, seizure medicines, and ulcer medicines, can interact with it. Make sure your doctor knows about any other medical conditions you may have. Some diseases and illnesses can change how your body responds to theophylline.

And keep in mind that not only is smoking and exposure to cigarette smoke especially dangerous when you have asthma, it can also interfere with how your body responds to the medication. So it’s best to avoid smoke and cigarette smoking.

Albuterol Oral Inhalation: MedlinePlus Drug Information

Albuterol comes as a solution (liquid) to inhale by mouth using a special jet nebulizer (machine that turns medication into a mist that can be inhaled) and as an aerosol or powder to inhale by mouth using an inhaler. When the inhalation aerosol or powder for oral inhalation is used to treat or prevent symptoms of lung disease, it is usually used every 4 to 6 hours as needed. When the inhalation aerosol or powder for oral inhalation is used to prevent breathing difficulty during exercise, it is usually used 15 to 30 minutes before exercise. The nebulizer solution is usually used three or four times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use albuterol exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Call your doctor if your symptoms worsen or if you feel that albuterol inhalation no longer controls your symptoms. If you were told to use albuterol as needed to treat your symptoms and you find that you need to use the medication more often than usual, call your doctor.

Albuterol controls symptoms of asthma and other lung diseases but does not cure them. Do not stop using albuterol without talking to your doctor.

Each albuterol aerosol inhaler is designed to provide 60 or 200 inhalations, depending on its size. Each albuterol powder inhaler is designed to provide 200 inhalations. After the labeled number of inhalations has been used, later inhalations may not contain the correct amount of medication. Dispose of the aerosol inhaler after you have used the labeled number of inhalations, even if it still contains some liquid and continues to release a spray when it is pressed. Dispose of the powder inhaler 13 months after you open the foil wrapper, after the expiration date on the package, or after you have used the labeled number of inhalation, whichever comes first.

Your inhaler may come with an attached counter that keeps track of the number of inhalations you have used. The counter also tells you when to call your doctor or pharmacist to refill your prescription and when there are no inhalations left in the inhaler. Read the manufacturer’s instructions to learn how to use the counter. If you have this type of inhaler, you should not try to change the numbers or remove the counter from the inhaler.

If your inhaler does not come with an attached counter, you will need to keep track of the number of inhalations you have used. You can divide the number of inhalations in your inhaler by the number of inhalations you use each day to find out how many days your inhaler will last. Do not float the canister in water to see if it still contains medication.

The inhaler that comes with albuterol aerosol is designed for use only with a canister of albuterol. Never use it to inhale any other medication, and do not use any other inhaler to inhale albuterol.

Be careful not to get albuterol inhalation into your eyes.

Do not use your albuterol inhaler when you are near a flame or source of heat. The inhaler may explode if it is exposed to very high temperatures.

Before you use albuterol inhaler or jet nebulizer for the first time, read the written instructions that come with the inhaler or nebulizer. Ask your doctor, pharmacist, or respiratory therapist to show you how to use it. Practice using the inhaler or nebulizer while he or she watches.

If your child will be using the inhaler, be sure that he or she knows how to use it. Watch your child each time he or she uses the inhaler to be sure that he or she is using it correctly.

To inhale the aerosol using an inhaler, follow these steps:

1. Remove the protective dust cap from the end of the mouthpiece. If the dust cap was not placed on the mouthpiece, check the mouthpiece for dirt or other objects. Be sure that the canister is fully and firmly inserted in the mouthpiece.
2. If you are using the inhaler for the first time or if you have not used the inhaler in more than 14 days, you will need to prime it. You may also need to prime the inhaler if it has been dropped. Ask your pharmacist or check the manufacturer’s information if this happens. To prime the inhaler, shake it well and then press down on the canister 4 times to release 4 sprays into the air, away from your face. Be careful not to get albuterol in your eyes.
3. Shake the inhaler well.
4. Breathe out as completely as possible through your mouth.
5. Hold the canister with the mouthpiece on the bottom, facing you and the canister pointing upward. Place the open end of the mouthpiece into your mouth. Close your lips tightly around the mouthpiece.
6. Breathe in slowly and deeply through the mouthpiece.At the same time, press down once on the container to spray the medication into your mouth.
7. Try to hold your breath for 10 seconds. remove the inhaler, and breathe out slowly.
8. If you were told to use 2 puffs, wait 1 minute and then repeat steps 3-7.
9. Replace the protective cap on the inhaler.
10. Clean your inhaler regularly. Follow the manufacturer’s directions carefully and ask your doctor or pharmacist if you have any questions about cleaning your inhaler.

To inhale the powder using the inhaler, follow these steps. Do not use the Respiclick inhaler with a spacer:

1. If you will be using a new inhaler for the first time, remove it from the foil wrapper. Look at the dose counter at the back of the inhaler and check that you see the number 200 in the window.
2. Holding the inhaler upright, with the cap on the bottom and the inhaler pointing upwards, load the dose by opening the protective dust cap at the end of the mouthpiece until it clicks. Do not open the cap unless you are ready to use the inhaler. Every time the protective cap is opened, a dose is ready to inhale. You will see the number in the dose counter go down. Do not waste doses by opening the inhaler unless you are inhaling a dose.
3. Breathe out as completely as possible through your mouth. Do not blow or exhale into the inhaler.
4. Place the mouthpiece between your lips well into your mouth. Close your lips tightly around the mouthpiece. Inhale slowly and deeply through your mouth. Do not breath in through your nose. Make sure that your fingers or lips do not block the vent above the mouthpiece.
5. Remove the inhaler from your mouth and hold your breath for 10 seconds or as long as you comfortably can. Do not blow or exhale through the inhaler.
6. Close the cap firmly over the mouthpiece.
7. If you are to inhale 2 puffs, repeat steps 2-6.
8. Keep the inhaler clean and dry at all times. To clean your inhaler, use a clean, dry tissue or cloth. Do not wash or put any part of your inhaler in water.

To inhale the solution using a nebulizer, follow these steps;

1. Remove one vial of albuterol solution from the foil pouch. Leave the rest of the vials in the pouch until you are ready to use them.
2. Look at the liquid in the vial. It should be clear and colorless. Do not use the vial if the liquid is cloudy or discolored.
3. Twist off the top of the vial and squeeze all of the liquid into the nebulizer reservoir. If you are using your nebulizer to inhale other medications, ask your doctor or pharmacist if you can place the other medications in the reservoir along with albuterol.
4. Connect the nebulizer reservoir to the mouthpiece or face mask.
5. Connect the nebulizer to the compressor.
6. Place the mouthpiece in your mouth or put on the face mask. Sit in an upright, comfortable position and turn on the compressor.
7. Breathe in calmly, deeply, and evenly for about 5-15 minutes until mist stops forming in the nebulizer chamber.
8. Clean your nebulizer regularly. Follow the manufacturer’s directions carefully and ask your doctor or pharmacist if you have any questions about cleaning your nebulizer.

What are Asthma Rescue Inhalers?

What are Asthma Rescue Inhalers?

Rescue inhaler medications also called quick-relief or fast-acting inhaled medications, work immediately to relieve asthma symptoms when they occur. They’re often inhaled directly into the lungs, where they open up the airways and relieve asthma symptoms such as wheezing, coughing, and shortness of breath, often within minutes. But as effective as they are, rescue inhalers don’t have a long-term effect. 

The most-prescribed rescue medications are quick-acting bronchodilators (usually given through an inhaler or a nebulizer), which loosen the tightened muscles around inflamed airways. The most common of these, beta2-agonists, are related to adrenaline and usually work within minutes to provide temporary relief of symptoms in asthma.

Rescue inhalers come by many names including Albuterol (Proventil, Ventolin), Metaproternol (Alupent), Levalbuterol (Xopenex), and Pirbuterol (Maxair).

A quick-relief inhaler for asthma: ProAir HFA is a quick-relief inhaler for asthma attacks. It works by opening up your airways, helping you to breathe. ProAir HFA may also help you if you have asthma symptoms related to exercise-induced bronchospasm.

Most fast-acting inhalers contain a medicine called Albuterol. Albuterol inhalers relieve bronchospasm. You may hear Albuterol inhalers being called by other names, including:

• Rescue inhalers
• Quick-relief inhalers
• Fast-acting inhalers
• Bronchodilators

No matter what you call them, the purpose of Albuterol inhalers is to quickly open the airways in your lungs so you can breathe more easily.

VENTOLIN HFA is an Albuterol inhaler that helps relieve bronchospasm and its symptoms.

VENTOLIN HFA acts within minutes, and asthma symptom relief should last 4 to 6 hours.

Side Effects of Rescue inhaler medications are:

• rapid heart rates
• restlessness
• headache
• muscle tremors
• low potassium
• sleep disorders

Your health care provider has a number of different quick relief medications to help treat your asthma. You likely will use a SABA as part of your asthma care plan, but overuse is a sign of asthma poor control. Your health care provider may also use steroids and anticholinergics in specific situations if your asthma has worsened. Understanding the role of each of these inhaled medications and their potential side effects will help you gain better control of your asthma.

What’s the Difference Between Rescue, Maintenance and Controller Inhalers?

“RESCUE,” “MAINTENANCE,” AND “CONTROLLER” INHALERS—WHAT’S THE DIFFERENCE?

Why two types of inhalers? Learn how different meds do different things.

If you’ve been diagnosed with COPD (which includes emphysema and chronic bronchitis), you may hear about “rescue,” “maintenance,” or “controller” treatments or inhalers. What does this mean?

Rescue medications are also called quick-relief medications. Rescue meds are taken as needed for quick, short-term relief of symptoms. They are used to prevent or treat the sudden worsening of COPD symptoms such as during a flare-up. They open the lungs by relaxing the muscles of the airway wall. They begin working within minutes and effects can last for four to six hours.

Maintenance or controller medications are taken daily to help manage symptoms of COPD.

Different people have different medication needs, depending on their condition. Ask your doctor about the treatment plan that works best for you.

How Much Albuterol is Too Much?

Asthma can cause shortness of breath, coughing, wheezing, and tightness in the chest, so it’s nice to have something handy that can eliminate those symptoms fast. That’s probably why your albuterol inhaler has quickly become your best friend! But there can be downsides to getting too much albuterol.

The question is, how do you know how much albuterol is too much?

When to Use Albuterol–at a Glance

• • Use your albuterol before hard exercise
  • Use your albuterol when you need it
  • Your program needs a change if you break either the Rule of 2 or the Rule of 4
  • Your program needs a change if your exercise control isn’t working

Taking too much albuterol can have very serious consequences. Our main concern is that you will soon be having severe asthma attacks leading to hospitalization or worse.

The Rule of Two

National and Global Asthma Guidelines indicate that a well-controlled asthmatic will need their rescue inhaler 2 or fewer times a week, most of the year. This is referred to as the “Rule of Two.” If you follow the rule of 2, you’ll generally use a maximum of 208 puffs of albuterol per year, which is less than one inhaler.

This means if you use more than one inhaler in a year, you may be using “too much” albuterol. And if that’s the case, you could need a better controller or prevention program. Be sure to talk to your doctor or asthma specialist about how you can best accomplish that given your symptoms.

Of course, most patients prefer to use their inhalers zero times per year, but that’s not always realistic! Following the Rule of Two is a good baseline to use when evaluating the frequency of your inhaler use. If you feel like you’re using your inhaler too often, contact our office!

The Rule of Four

Another way I evaluate my patient’s asthma is by evaluating how often they need their albuterol over a short time period.

These presentations indicate that fast intervention is needed to gain control of your asthma. The treatment provided can range from systemic steroids all the way to simple allergy avoidance (such as politely leaving your cat-owning friend’s house if you are allergic to cats).

Some studies show that a portion of patients who use albuterol four times a day as a routine may find that their asthma grows worse due to the practice. As a result, most asthma specialists will recommend finding ways to better control your symptoms.

Albuterol and Exercise

(The Exception to the Rules)

When I talk about the Rule of Two or the Rule of Four with patients, I usually get a lot of questions about exercising. Usually, your asthma specialist will advise you to utilize your inhaler prior to vigorous exercise. The two puffs of albuterol you take before exercise do not count in the Rule of Two or the Rule of Four.

However, if you find that you’re still having asthma attacks even after utilizing your inhaler prior to exercise, then you should see your asthma specialist to adjust your asthma program.

The Less Albuterol, the Better

When you can’t breathe, you know as well as any other asthmatic that you will do just about anything to get your breathing back to normal. Asthma attacks can be a frightening experience! Being a doctor that specializes in asthma treatment, the frequency of albuterol use is one of the tools used to gauge asthma control – less albuterol means better asthma control! We now have so many asthma controllers to choose from—working together we can find the right program for your particular type of asthma.  

That said, if you’re experiencing symptoms, it’s appropriate to address those symptoms with your inhaler. We use the Rule of Two and the Rule of Four not to restrict your inhaler use, but to identify when your asthma could use a little more clinical attention. The goal of that clinical attention is to let you forget about your inhaler for a while–or, at least, not use it so often.

Trust me, your albuterol inhaler won’t mind not being your best friend!

If you have questions or concerns about your asthma program, feel free to contact Dr. Bubak at Dakota Allergy and Asthma at 605-336-6385.

Asthma patients should use ICS-LABA for rescue as well as maintenance, SMART says

In Europe, patients with asthma have long been advised to take more puffs of their combination inhaled corticosteroid-long-acting beta-agonist (ICS-LABA) inhaler during periods of increased asthma symptoms. In the U.S., patients are instead advised to use albuterol as their rescue inhaler, and stick firmly to the usual maintenance dose of ICS-LABA regardless of symptom severity.

A potentially practice-changing meta-analysis of 16 randomized trials showed the European method of boosted dosing during symptomatic periods — dubbed the SMART strategy in the analysis — was superior to the U.S.’s consistent-dosing approach.

Patients using ICS-LABA as a rescue as well as maintenance inhaler treatment experienced significantly fewer asthma exacerbations, hospitalizations, and emergency department visits, compared to those using ICS-LABA for maintenance and albuterol for rescue. The findings were reported in JAMA.

The SMART trials enrolled 22,500 patients total (almost all adults). Those using the ICS-LABA (budesonide-formoterol) as maintenance + rescue strategy had a 32% fewer asthma exacerbations compared to patients taking an equivalent dose of ICS-LABA who used albuterol as rescue.

More impressive, the patients in the budesonide/formoterol maintenance + rescue arm had 23% fewer exacerbations than patients taking higher doses of ICS-LABA as maintenance therapy, who used albuterol as rescue. The SMART strategy was also superior to ICS monotherapy as maintenance, with albuterol as rescue.

The benefits of ICS-LABA as rescue-plus-maintenance were even larger in children aged 4-11 years, with roughly 50% reductions in exacerbations compared to conventional strategies.

The SMART analysis was in contrast to recent studies published in NEJM showing that increasing inhaled steroids alone was an ineffective way of aborting asthma exacerbations in children or adults.

One small caveat was that the ICS-LABA used in the studies was a dry powder; in the U.S., this specific ICS-LABA preparation (budesonide-formoterol) is an aerosolized metered dose inhaler sold as Symbicort. Implementation of the SMART strategy in the U.S. would result in patients burning through their ICS-LABA controller inhalers (e.g., Advair, Symbicort, Dulera, et al) at an increased and unpredictable rate, confounding pharmacists and insurers.

Current U.S. asthma guidelines are more than a decade old, and experts predicted a major revision which will incorporate the SMART strategy and also endorse long-acting muscarinic antagonist (LAMA) use as an adjunctive therapy to inhaled steroids for asthma maintenance.

90,000 symptoms of an attack, first aid for asthma

Asthma attack. Photo: Pixabay

An asthma attack can be taken by surprise. Its main symptoms are shortness of breath, cough, and chest tightness. The cause may be allergens, polluted air, illnesses like the flu, or energetic
physical exercise.

How to recognize an asthma attack and what to do?

On average, every 13th person in the world suffers from some form of asthma. This is a condition that causes swelling of the airways and makes it difficult to breathe.When you have an asthma attack,
symptoms such as coughing or breathing problems can become serious or even fatal if first aid is not given properly. Here’s how to know if you have an asthma attack, and how
treat symptoms.

Signs and symptoms of an asthma attack

The difference between asthma and status asthma (acute respiratory distress syndrome) lies in the severity of the symptoms. In this case, the symptoms themselves are basically the same.

If you suffer from asthma, you are likely already familiar with most of the symptoms of an asthma attack, only in milder forms.

Some of the more common symptoms of an asthma attack include:

• severe shortness of breath;

• labored breathing;

• cough;

• heaviness in the chest, inability to inhale.

Causes of an asthma attack

An asthma attack occurs when the bronchi or airways become inflamed or blocked. The muscles around these “tubes” contract and contract, making breathing difficult.

Common causes of an asthma attack:

• allergens such as mold, pets, or dust mites;

• airborne irritants such as smoke, perfume, air fresheners, or other chemical odors;

• flu or respiratory infection;

• vigorous exercise.

There are other medical problems that can be confused with asthma, for example, it can be very difficult to distinguish an asthma attack from an allergic reaction.

In some cases, if you have asthma, an allergic reaction can trigger an asthma attack. This can happen if you breathe in air containing allergens such as pollen or dust.

People suffering from anxiety attacks may also experience shortness of breath and chest tightness. However, this condition differs from an asthmatic attack in the absence of a feeling that you cannot do
inhale.

How to treat an asthma attack

The first line of defense against an asthma attack should be an inhaler filled with albuterol, a bronchodilator that relaxes the muscles in the airways.But if the inhaler is not at hand or it is not
helps, you need to urgently call an ambulance.

If you have severe asthma, it is helpful to always have a rescue inhaler with you so you can be ready in the event of a sudden attack. People with similar problems usually keep their inhalers in
purse, backpack or pocket, so that it is always at hand.

Rapid-acting, or “rescue” inhalers usually contain albuterol, a medicine that helps open the airways.Taking albuterol should quickly relieve symptoms such as wheezing and
dyspnea.

If you still experience asthma symptoms after using the inhaler, you can take albuterol again after 20 minutes. But if after the second course of treatment you still feel a strong
shortness of breath, you should immediately contact an emergency clinic or doctor.

Young children, who may have trouble using inhalers, also take albuterol with a nebulizer – a device with a plastic tube that ends in
mouthpiece.It disperses the medicine in the form of a “mist”.

If your symptoms are so severe that you cannot talk because of shortness of breath, and your lips or face are slightly blue, you should seek immediate medical attention.

If you do not have an inhaler, call an ambulance.

If you do not have access to a rescue inhaler, the first step is to call an ambulance. You should do this even if it appears to be just a mild asthma attack, as it may
escalate quickly.

While waiting for help, focus on breathing slowly, evenly. For this:

1. Make sure you move away from any asthma pathogens such as pollen or smoke.

2. Sit up straight and do not lie down so that the airway is completely open.

3. Try to slow down your breathing so that you can breathe in two counts and then breathe out two more. Breathing in more than 30 times per minute is considered rapid breathing and can worsen symptoms.

4. Try to inhale through your nose and exhale through your mouth to keep yourself from hyperventilating.

5. Breathing slowly will also help you not panic, which is important as panic can cause hyperventilation and make the condition worse.

Emergency medical care

Further treatment will depend on how severe the asthma attack is. For moderate seizures, treatment may include:

• albuterol taken with a nebulizer, as this can deliver the drug deeper into the lungs;

• steroid pills that can reduce inflammation in the lungs by helping you breathe easier.

Other treatments for severe asthma attacks include:

• Oxygen is delivered through a mask that will ensure that sufficient oxygen is delivered to the lungs, even if breathing is still difficult.

• in life-threatening cases, you may be placed under a ventilator to take over breathing while doctors continue to treat an asthma attack.

be ready

Although many asthma attacks are mild and can be treated with an inhaler, if you are concerned about new symptoms or are in doubt about the effectiveness of the inhaler, it is best to seek
emergency care.Asthma attacks should never be taken lightly.

Children’s asthma inhalers

Inhalers are the mainstay of asthma treatment, including for children who are old enough to know when and how use them. This is when children can remember to use a regulator inhaler at a specific time, as prescribed by a doctor, and recognize the onset of an asthma attack, which signals the need to use an emergency inhaler to suppress wheezing and other symptoms in the fetus.

Many, but not all, medicines prescribed for adults with asthma are approved for use in children; some are only suitable for children 12 and up, but not for younger children. If you have a child with asthma, their doctor will be able to determine which asthma inhalers are best for them based on their age and the severity of asthma.

As a parent or guardian, it will be helpful for you to know what medications are being prescribed for your child, how to best use them, and what alternatives if treatment changes need to be made.

Infants and very young children with asthma who are not yet able to control an inhaler usually receive inhaled medication through a nebulizer that converts the medication into a mist that can be inhaled through a mask or mouthpiece that is worn over their nose and mouth.

Controlled inhalers

Controlled inhalers for asthma contain corticosteroids, drugs that prevent inflammation. In this way, they prevent swelling and excess mucus production that can cause wheezing, shortness of breath, and other common symptoms of asthma.

Inhaled corticosteroids (ICS) are important for the treatment of asthma. Because they are designed to help prevent worsening symptoms and asthma attacks, they must be used regularly. For most children, this means several times a day on a set schedule.

Some children 12 years and older with mild persistent asthma may not need to use ICS every day, according to the asthma treatment guidelines updated by the National Institutes of Health in December 2020.These children can use ICS and a short-acting inhaler. as needed.

When giving your child a control inhaler, their doctor will likely start with the lowest dose needed to control your child’s symptoms.

Rescue inhalers for asthma

Rescue inhalers are used as needed when a child feels like he or she is about to have an asthma attack, depending on the onset of symptoms (wheezing, chest tightness, shortness of breath, etc.)Etc.). These inhalers are not intended for regular use.

Emergency inhalers contain bronchodilating drugs that dilate the bronchi (airways) leading to the lungs. A narrowing of the airways or narrowing of the bronchi is a key aspect of asthma, along with inflammation, swelling, and excess mucus.

The most commonly prescribed lifesaving agent for children (and adults) is albuterol (aka salbutamol), a short-acting beta-agonist that relaxes the airways so they can expand more easily.It is available under several brand names and also as a generic drug.

If your child needs an inhaler for pain relief more than twice a week, tell their pediatrician. Frequent flare-ups of symptoms may be a sign that your child’s inhaler controller needs adjustment.

Combined inhalers

For children 4 years and older (and adults) with moderate to severe chronic asthma (the two most severe categories of asthma), the NIH recommends an inhaler containing two drugs: ICS and a drug called formoterol, a long-acting beta-agonist (LABA ).

This combination inhaler should be used both as a control medicine for daily use and as a rescue therapy for the relief of acute symptoms.

Device types

There are two types of inhalers: metered-dose inhaler (MDI) and dry powder inhaler (DPI).

While it is ideal to use the medication that best controls asthma, the effectiveness of any medication depends on how well it is used.Each of the MDI and DPI delivers medication in a slightly different way, and your child may feel that one device is easier to use than the other.

DPI

DPI are breath activated, which means the medicine is released when your child inhales deeply and forcefully.

PI is usually not given until children are 5 or 6 years old because young children cannot inhale strongly enough to receive the full dose.Exceptions are Advair Disk and Asmanex Twisthaler, which can be prescribed for children aged 4 years and older. Some older children prefer the level of control that DPI offers.

CI

The

MDI releases the medication automatically and requires the coordination of deep breaths while the inhaler is operating. 5 They contain hydrofluoroalkanes (HFA), a substance that propels the drug under pressure.

(Another type of MDI that uses chlorofluorocarbons (CFCs) to pressurize a drug has been discontinued by the FDA 6).

Tips for using the inhaler

Children may have difficulty learning how to use the inhaler. For example, children who take MDIs often breathe too quickly instead of taking slow and deep breaths while taking the medication.

Other common problems:

• Blowing into the inhaler instead of inhaling

• Incorrect installation of the inhaler

• Forgetting to exhale completely before using the inhaler

• Do not hold your breath for about 10 seconds after inhaling the medicine.

• Forgetting after slow exhalation

The spacer is a small device that can be attached to an MDI inhaler. It has a storage room that stores the medication until the baby breathes in, so they don’t need to coordinate their breath with the inhaler activating.8 Pads come in a variety of shapes, including masks for babies, toddlers, and children under 4. …

The child can use the spacer as much as he needs, usually between the ages of 8 and 10.

Word from Verywell

An asthma action plan can help you and your child understand when to use daily inhalers and when to use life-saving inhalers. Consult your child’s pediatrician if you need help explaining the importance of age-appropriate asthma treatment for your child, and help develop this understanding as he ages.

90,000 HOW TO STORE INHALERS FROM ASTHMA. – MEDICAL

Contents:

Asthma inhalers are a quick and convenient way to deliver medicines to relieve asthma symptoms 1. Inhalers are the preferred method of delivering both bronchodilators, such as albuterol, which quickly open the bronchi and allow the patient to breathe easier; and anti-inflammatories such as salmeterol, which reduce airway inflammation over time.If you have asthma, you may have more than one inhaler and you can store them in different places, such as in your purse, gym bag, or on your bedside table 1. For your inhaler to work properly, you must take some precautions when storing. …

Is this an emergency?

Seek emergency help immediately if you experience severe medical symptoms.

Close the inhaler cap after each use. This prevents dust and dirt from entering the mouthpiece and prevents anything from entering the inhaler and blocking the action.

Store the inhaler in a clean place. You can store the rescue inhaler in a gym bag or backpack for easy access, but sharing space with dirty sports socks is bad for you and the inhaler. Instead, place the inhaler in a sealed zippered bag. It will still be close at hand when you need it, but it will always be clean.

Keep the inhaler away from extreme heat and cold. The glove compartment of your car may seem like a convenient place to store your inhaler, but the extreme heat and cold that the inhaler will be exposed to in your car can alter the drug and make it ineffective. A patient information sheet for one form of albuterol, the brand name Proventil, warns that the inhaler can burst at temperatures above 120 degrees 2. (Ref 2) Proventil manufacturers recommend storing it at 59 to 77 degrees Fahrenheit, which is good. range for all inhalers.

Warnings

The inhaler must be at room temperature before use. If it’s cold, warm it up in your hands. Never try to warm it up with a match or under running water.

Contents

When you have asthma, it is important to know how long your inhaled medications will last and to be able to determine when you are running out.While some inhalers have a counter to help you keep track of, others don’t, which means it’s up to you how much more benefit you can get from them. This can be especially difficult with life-saving inhalers that are used only when needed.

You will know when the preloaded inhaler is empty; these inhalers usually contain 50 to 200 doses of medication, and eventually they will just run out. Though obviously it’s best not to wait for this to happen to restock.

But metered-dose inhalers (MDIs or HFCs) contain a chemical that will continue to spray even after the medication is used up, which means you can use it without actually getting treatment if you haven’t tracked your doses.

How you store your inhaler and when it expires also affects how long your inhaler will last you.

Number of Uses

Maintenance inhalers, also called controllers, are inhalers you take every day to help prevent asthma symptoms.Rescue inhalers are inhalers that you need to take when you have symptoms or have a sudden asthma attack.

Whether you have a meter for tracking doses in your inhaler depends on the specific medication you are prescribed, not which type of inhaler you are using.

Metered inhalers

Metered inhalers will keep track of the amount of medication you have left.

For example, your Flovent HFA inhaler has a counter that shows you how many nebulizers you have left.The counter starts at 124 and counts down one unit each time the inhaler is sprayed. The counter will stop counting to 000, after which the manufacturer recommends that you no longer use it.

Another controller, Qvar (beclomethasone dipropionate HFA), is supplied as an MDI with 120 inhalations per canister. It has a counter that reads zero when the expiration date expires or when the product is used up, whichever comes first.

Inhalers without a counter

If your inhaler does not have a counter, the number of puffs in each canister should be printed on the inhaler label.

Controlled inhalers

For a controlled inhaler, you can calculate the number of days of use you will get without the inhaler by dividing the total number of doses in the bottle by the total number of doses you are prescribing per day. You can then use the calendar to determine when you will run out of medication.

Symbicort is a preparation containing budesonide (steroid) and formoterol fumarate dihydrate (long-acting bronchodilator).This medicine is sold in cans of 60 or 120 doses each.

Feel free to ask for help. If you are not familiar with the specific packaging, the labeling is not always obvious. And once you have counted the number of doses and the day that you expect the drugs to run out, it is advisable to double-check your calculations with the pharmacist.

Be sure to keep track of this information by writing down the start and end dates of your medication on your canister when you pick it up. And plan ahead for your next supply so you don’t miss a single treatment session.

Rescue Inhalers

Tracking when an emergency inhaler runs out is harder than keeping track of controllers because you won’t be using the same dose of Rescue Medication every day.

It is impossible to predict how many doses of the Rescue Inhaler you will need. And it’s unrealistic to expect you to remember how much you used.

Albuterol, a bronchodilator that widens the airways, is a widely used inhaler for emergency use.Supplied in an 8.5 gram canister containing 200 puffs of medication.

The albuterol manufacturer warns against using methods or ‘gimmicks’ to try to figure out how much medicine is left in a canister, with a notification that never immerse the canister in water to determine how full it is (called a ‘floating test’ ).

You can keep a log of how often you use the rescue inhaler. In addition to helping you determine when you need a refill, it will also help you gauge how well your controllers are performing.If you use an emergency inhaler on a daily basis, your doctor may make changes to the medication you control to reduce the frequency of your asthma symptoms.

Monitoring Asthma for Better Control

Expiration date

Of course, it is important to have a complete inhaler, but if the expiration date of this medicine has expired, chances are that the medicine has not retained its strength, quality and purity. Therefore, pay attention to the expiration date of your inhaler. It is equally important to consider how long this will last.

Expiration can be a serious problem for any medication, but it is especially important for life-saving inhalers, which you may rarely use if your asthma is well controlled. While you may feel safe in the knowledge that you have an inhaler, this inhaler may not be effective after you use it if it has passed its expiration date.

For example, if you are using albuterol, make sure you schedule a repeat dose before the expiration date of the inhaler, even if you are unlikely to ever need it.You don’t want to be caught without a safe and effective rescue inhaler when you suddenly need one.

According to the US Food and Drug Administration (FDA), the shelf life of a drug depends on its chemical stability.

When using Qvar, the counter will show 0. When the expiration date is reached, for other inhalers the expiration date is indicated on the packaging and on the inhaler itself; by law, all medicines must have an expiration date.

Please note that the expiry date is only valid if your inhaler is stored according to the manufacturer’s instructions. Medicines can become unstable and therefore ineffective or unsafe if not stored properly.

Storage and Disposal

Most medicines, including inhalers, must be stored at the optimum temperature. For example, you can leave the inhaler in your car for convenience, but remember that high or low temperatures can affect your medication intake.

Humidity, for example in the bathroom, can also change the chemistry of the medicines used in your inhaler. Humidity can also slightly wet your device, affecting the dose that is administered with each breath.

Each inhaler will have a specified temperature and storage recommendation, so be sure to read the labels or ask your pharmacist for advice.

For example:

• According to the manufacturer, albuterol should be stored between 59 and 77 degrees Fahrenheit.Container may explode at very high temperatures.
• Symbicort should be stored at room temperature between 68 and 77 degrees Fahrenheit with the inhaler mouthpiece lowered.

When you are finished with the inhaler or it has expired, it is best not to throw it in the trash can. Since drugs may remain inside it, there is a possibility that it could explode when exposed to high temperatures (for example, in a garbage truck). Medicines and propellants can also be released into the environment.

Instead, talk to your pharmacist to see if they can dispose of your inhaler. Some pharmacies constantly have containers for dispensing medicines; others may have special days or return events. The same can happen from time to time in the local government or in the police / fire department.

A word from Verywell

Asthma inhalers directly reach the lungs, providing a therapeutic effect. They can be convenient to use, but it is not easy to see how many drugs you have left.Once you start regularly replacing, storing and caring for your inhaler, you will feel more comfortable with the entire process.

Please be aware that not all of your inhalers will last the same length of time, and each may have its own storage characteristics and expiration dates.

Quantitative Mapping of Specific Ventilation in the Human Lung using Proton Magnetic Resonance Imaging and Oxygen as a Contrast Agent

One SVI Slice in a Healthy Object
Specific Ventilation Tomography produces quantitative specific ventilation maps as shown in Figure 3A, on which depicts one slice in the right lung of a 39-year-old healthy female.Note the presence of the expected vertical gradient in the specific ventilation; the dependent part of the lung presents a higher specific ventilation than the independent part of the lung. A histogram of displayed specific ventilation values ​​ (Figure 3B, filled circles) is presented along with the most appropriate logon probability distribution function (dashed line). The best distribution width can be used as a metric for specific ventilation heterogeneity ^7.23 . Figure 1 shows multiple flushing of breath acquired in the same object, in the same pose. Figure 1A shows a temporal lobe record of nitrogen concentration measured in the mouth after changing from inspirational air to inspirational 100% oxygen. Figure 1B shows the specific ventilation distribution as calculated from the flush. For SVI and MBW, the corresponding variable is the distribution width, measured here by the width of the normal distribution of the log set on the data (dashed line), it was found to be 0.41 using SVI and 0.42 using MBW within a healthy normal range. Estimated estimated ventilation heterogeneity compared to MBW was tested in 10 subjects, and ^{found that the difference between methods was less than the variability of the intertest mbW 7. Spatial comparison with hyperpolarized gas multi-day specific ventilation imaging 16 also showed reliable group estimates of specific inhomogeneity of ventilation (the width of the specific ventilation distribution in 8 studied subjects was 0.28 and 0.08 and 0.27 0.10 for hyperpolarized 3 He and specific ventilation images, respectively), despite higher than expected intra-object variability (standard deviation of individual differences in width was 0.13) 16 .}

Special ventilation maps can also be used in conjunction with lung density maps to calculate regional alveolar ventilation. To generate alveolar ventilation maps, specific ventilation and image densities must be spatially smoothed to minimize potential minor inconsistencies between the two modalities.

Response to Methacholine Challenge in Asthmatic Topic
SVI can be used to measure both lungs in general and regional responses to activities such as exercise ⁴ , posture ² , or medication ³ .As an example, Figure 4 depicts single-slice maps from the lungs of a mild asthmatic female subject at baseline (Figure 4A ), after bronchial suction with methacholine ( Figure 4B ), and after albuterol assisted recovery ( Figure 4C ) … Note the increased specific heterogeneity of ventilation during induced asthma, as well as the presence of large spots with little or no specific ventilation (dark blue areas in the dependent part of the lungs).Also note that in some regions during bronchosuctosis (green-red areas) in some regions, ventilation increased markedly.

Multi-layered SVI
Up to six (usually four), contiguous, 15 mm lung slices can be simultaneously imaged with the SVI. Figure 5 depicts four contiguous slices of the right lung covering 70% of the right lung in a moderate asthmatic male subject who was withdrawn from his asthma medications within 24 hours.

Ventilation map
Provided that lung density information was obtained in the same slice and the respiration rate is known, a fully quantitative ventilation map can be calculated in units of mL / min / ml. An example of a ventilation map is shown in Figure 6 .

Figure 1. Multiple breath washout. ( A ) Typical mW trace showing expired nitrogen (N ₂ ) concentration (top) and tidal volume (bottom) over time (seconds, s).The data was obtained in a supine position; the subject was a healthy 39-year-old woman. ( B ) Histogram depicting the distribution of a particular ventilation (SV) calculated in the MBW experiment using the method proposed by Lewis et al. ²³ (solid line). The broken line represents the gaussian best suited to the particular ventilation distribution. The inhomogeneity of specific ventilation, a key result, is measured as the width of the best distribution, in this case 0.42.This figure has been reprinted with permission from reference ⁷ .

Figure 2. Diagram of the plumbing system and appliances. Specific ventilation tomography requires 100% medical oxygen, either from a compressed gas tank (drawn) or a wall outlet. The oxygen source is connected to a valve commutator (control room), which in turn connects, via MRI, to a 3D printed flow bypass system ^24, attached to a face mask (scanner room).The left side of the figure corresponds to the MRI control room, the right side to the scanner room. The plastic tubing that connects the tank to the switch is 1/4 inch in diameter. The tubing from the switch valve receptacle to the bypass flow system is also 1/4 in. The last 2 m includes a step up in diameter, from 1/4 in. To 3/8 in. And then up to 1/2 in. To reduce noise. produced by air flow ²⁴ .

Figure 3. Specific ventilation tomography. ( A ) Typical specific ventilation map (color) superimposed on anatomical MRI images of the same object on the back (gray scale). Specific ventilation ranges from very low values ​​(blue) to SV 1.0 (red). Subject, a 39-year-old healthy volunteer (the same object as in Figure 1 ) was depicted in a supine position.Note the vertical gradient in specific ventilation. A phantom of a known MR characteristic used for absolute density calibration was placed in the anterior chest wall. Phantoms are not required to quantify SVI. ( B ) Histogram of the distribution of specific ventilation (filled circles), compiled from a specific ventilation map. The distribution width is the heterogeneity of specific ventilation in the studied section of the lungs. In this example, the distribution is non-modal and the register width of the Gaussian fixed distribution (dashed line) is 0.41; this is comparable to the MBW of the total lung specific ventilation distribution presented in Figure 1B , for the same apparatus and posture, where the distribution width) was 0.42.Please click here to view a larger version of this figure.

Figure 4 Photo 4. Maps of bronchoconstriction and bronchodilation in lung asthma. Specific ventilation is measured in mild asthmatic subject (female, age 24) at baseline (A), after inhalation of 1 mg / ml methacholine (B) and after inhalation of albuterol (C). Note significant changes in the distribution of specific ventilation following asthma induction, as an event with methacholine use (panel B), with large dependent lung areas showing very low specific ventilation.Also note the recovery after bronchodilator administration (Panel C). As and Figure 3, specific ventilation maps were superimposed on anatomical MRI.

S-stereoisomer found in racemic albuterol may have associated pro-inflammatory properties. We tested the hypothesis that airway inflammation, as measured by exhaled nitric oxide, does not differ in COPD patients with racemic albuterol versus levalbuterol or placebo.

Twelve patients with mild to moderate COPD were administered each of the nebulized racemic albuterols, levalbuterol, and saline placebo for five days.Before and after each course of treatment, airway inflammation was assessed through breathing with exhaled nitric oxide. Secondary functional outcomes that were measured included spirometry, functional assessment using a six-minute walk, and symptom assessment using the University of California, San Diego. Short term question about breathing.

There was no statistically significant difference in pre and post FeNO levels within and between treatment groups (p = 0.121). There were also no significant differences within or between treatment groups for secondary FEV1 measurements (p = 0.913), functional assessment using a six-minute walk (p = 0.838), and symptom assessment using the shortness of breath questionnaire (p = 0.500).

We found no difference among patients with mild to moderate COPD who received racemic albuterol, levalbuterol, or placebo to measure exhaled nitric oxide or the secondary outcomes that were measured.

Chronic obstructive pulmonary disease (COPD) is a disease characterized by airflow restriction that is not fully reversible and progressive chronic inflammation in all airways, parenchyma and pulmonary vasculature (GOLD 2005).Various bronchodilator drugs, including β2-agonists, are commonly used in the treatment of COPD. β2-agonists bind to the β2-receptor and relax airway smooth muscle, reducing airflow obstruction. They are recommended both on a regular basis and as needed (GOLD 2005).

Albuterol, a short-acting β2 agonist, is available as a racemic formulation that consists of the (R) and (S) isomers in a 50:50 mixture or as one (R) isomer (levalbuterol).The (R) isomer is predominantly responsible for the bronchodilatory effect and the side effects of tachycardia, tremor and nervousness (Handley 2001). The (S) -isomer, considered inert due to its weak binding to the β2-adrenergic receptor, has been reported to have potentially deleterious effects (Handley 1999, 2001; Page and Morley 1999) to enable the promotion of bronchoconstriction and bronchial hyperreactivity (Mazzoni et al. , 1994, Wang et al., Gauvreau et al., 1997, Templeton et al., 1998). In addition, the (S) -isomer has been reported to have various pro-inflammatory effects, including changes in cytokine production (Gavreau et al., 1997; Frieri et al., 2000; Cho et al., 2001; Baramki et al., 2002), increased histamine production (Cho et al., 2001), and increased nitric oxide release in stimulated small epithelial cells of the airways (Frieri) et al., 2000).

Because chronic inflammation can contribute to an accelerated loss of lung function, the use of levalbuterol has been considered due to concerns about the inflammatory potential of the (S) -isomer (Costello 1999). Although there is information that the (S) -isomer can induce inflammation in asthma staging, to our knowledge, there are no studies investigating the presence of an inflammatory response in the setting of COPD.In this study, we tested the hypothesis that airway inflammation, as measured by exhaled nitric oxide, does not differ from COPD patients when sequentially comparing nebulized racemic albuterol, levalbuterol, or placebo.

Airway inflammation was assessed by measuring the fraction of exhaled nitric oxide (FeNO), a marker of airway inflammation. Compared to baseline or normal controls, elevated FeNO levels have been reported in the setting of COPD (Agusti et al 1999; Corradi et al 1999; Ansarin et al., 2001; Kharitonov and Barnes, 2004), chronic bronchitis (Delen et al 2003) and Exacerbation of COPD (Maziak et al 1998, Agusti et al 1999). In addition, inhaled corticosteroids have been shown to reduce baseline elevated FeNO levels in stable COPD (Zietkowski et al., 2005), suggesting that FeNO may serve as a surrogate measure of chronic inflammatory airway inflammation at baseline, which is improved by the use of inhaled corticosteroids. …

Study conducted at Wilford Hall Medical Center and Brook Army Medical Center in San Antonio, Texas.Patients 18 years of age and older who had a 10-year history of smoking, no recent tobacco use in the six months preceding enrollment, and mild to moderate COPD as measured by a one-second baseline forced expiratory volume (FEV1 ) / forced vital capacity (FVC) less than 0.70 and an FEV1 projection greater than 50% were included in the study. The Research Council at Brook Army Medical Center approved the study, and all patients gave written informed consent.

Twelve patients were enrolled in the study. They were randomized, but not blinded, to complete three separate five-day treatments. Treatment groups consisted of albuterol (2.5 mg four times daily), levalbuterol (0.63 mg three times daily with one placebo dose in saline solution), and 5 ml saline placebo four times daily. All drugs were administered via a nebulizer (PARI LC nebulizer, Midlothian, VA), which the patients took away with them. Each patient received instructions on how to properly use the nebulizer device and administer the medication.They were also tasked with completing a home diary recording their medication use. There was a minimum two-day washout period between treatment groups during which patients abstained from COPD medication. All patients received an albuterol metered dose inhaler (MDI) that could be used for rescue purposes at any time during the study. However, the use of life-saving inhalers became the basis for exclusion from further participation in the study.None of the participants used lifesaving treatment throughout the study.

Patients were excluded from the study if they had an exacerbation of their COPD requiring adjustment for COPD treatment, the addition of an oral corticosteroid, or the administration of antibiotics within 6 months prior to enrollment in the study. Patients were also excluded if they had a history of hospitalization for COPD. Additional exclusion criteria included use of an inhaled corticosteroid regimen or phosphodiesterase inhibitor (i.e., theophylline) during the previous month, use of an oral β-blocker, long-acting inhaled β-agonist, antihistamine, or nasal corticosteroid during the previous week of participation or participation in the process.Patients could not have evidence of concurrent restrictive lung disease on lung function testing, or 12% or greater improvement in FEV1 after bronchodilator administration. All patients who experienced exacerbation of COPD during the study period were excluded from the study continuation (n = 1).

The main result of the study was the measurement of FeNO. Based on a previous study (Agusti et al 1999) in clinically stable COPD patients after an exacerbation, we hypothesized a mean exhaled nitric oxide level of 15.8 ± 3.8 ppb at baseline.It was noted that the 2.4 standard deviation increase in FeNO was significant. Our study was calculated at 80% to find this difference at a 95% confidence level. Nine subjects, acting as their own controls, were required to detect the difference with the desired levels of power and confidence.

FeNO measurements were performed using the NIOX® nitric oxide monitoring system (Aerocrine AB, Sweden) at a flow rate of 50 ml / sec and reported as parts per billion (ppb).FeNO levels were measured both before and after completion of each treatment group and were performed according to guidelines published by the American Thoracic Society (ATS 1999).

Secondary outcomes that were measured included spirometry, a functional assessment using a six minute walk, and symptom scores using the University of California, San Diego, Short Term Breathing Question (SOBQ) (Eakin et al 1998). The Sensorimedics 6200 was used for spirometry to record FEV1, FVC and FEV1 / FVC.The six minute test (6MWT) was conducted in accordance with the guidelines described by the American Thoracic Society in their 2002 statement (ATS 2002). The MeterMan Measuring Wheel (Model 1212) was used to measure the distance the patient was staying over a six minute period. A difference of 54 meters at a distance of six minutes was considered clinically significant based on previous estimates (Redelmeier et al 1997). SOBQ has been used with permission from the University of California, San Diego Lung Rehabilitation Program.Based on previous guidelines, a 5-unit change for SOBQ was considered the minimum clinically significant difference (Kupferberg et al 2005). Secondary outcomes were obtained at the end of each treatment group and compared to baseline measurements.

Data were analyzed using SPSS Sample Power, version 2.0 (SPSS Inc, Chicago, IL). The distribution of FeNO values ​​did not differ significantly from the norm on the Kolmogorov-Smirnov test (p> 0.05) and, therefore, was analyzed by parametric testing.Paired t-test was used to assess the differences in FeNO between treatment times. Repeated measures ANOVA using paired t-test for FeNO, FEV1 and six minutes of walking by treatment were used for group comparisons. The Hyun-Feldt statistic was used to analyze pooled SOBQ scores for between group comparisons, as data were not usually distributed.

Patient characteristics are shown in Table 1. The average age of our patients was seventy years and ranged from fifty-five to eighty.There were nine men and three women. All patients had a baseline obstructive FEV1 / FVC ratio of less than 0.70. Baseline FEV1 was normal in four patients, mild in five, and moderate in three. Ten patients completed the study. One patient responded a second time on transportation issues. Another responded secondary to an exacerbation of COPD that occurred with a placebo that required treatment. No other patient reported using albuterol for rescue purposes during the study.

Mean pre- and post-treatment FeNO levels for all patients in each treatment group are shown in Table 2. Data are presented in intent-to-treat format and include two participants who were ultimately excluded from the study. Due to the limitations of statistical methods, the rest of the calculations include only 10 subjects who completed the study. In the analysis of these patients, the mean FeNO levels and standard deviation were as follows: levalbuterol (up to 27.3 ± 19.1 ppb, post-26.1 ± 20.6 ppb), albuterol (up to 30.6 ± 24.4 ppb, post -28.9 ± 22.4 ppb)) and placebo (up to 26.9 ± 20.5 pbb, after 23.8 ± 15.0 h./ billion). The comparison between groups in FeNO is noted in the diagram in Fig. 1. Statistically significant difference in FeNO between treatment groups (p = 0.121). The number of patients twelve was dropped, and after re-examining the medical data and the patient’s condition, we were unable to explain the elevation in FeNO. This patient’s data were included in the analysis. Reanalysis of the treatment effect with highlighted number twelve did not change the meaning of our results.

Results for secondary results measurements are listed in Table 3.There were no differences within or between treatment groups for FEV1 (p = 0.913), functional assessment using 6MWT (p = 0.838), and symptom scores using SOBQ (p = 0.500). Complete SOBQ data were available for eight patients. Increases of 6.25 and 4 units in SOBQ were noted with levalbuterol and albuterol, respectively, from baseline.

Given the associated pro-inflammatory potential of the (S) -isomer of albuterol, our study was designed to determine if airway inflammation as measured by FeNO was different in COPD patients treated with albuterol compared with levalbuterol or placebo.We expected to measure the growth of FeNO if the (S) -isomer of albuterol was associated with the induction of inflammation. In addition, we aimed to determine whether there were significant differences in racemic albuterol or levalbuterol relative to placebo in terms of improved spirometry, functional assessment using 6MWT, and symptom scores using SOBQ.

We found no differences within or between treatment groups for FeNO measurements, spirometry, functional capacity, or symptoms.However, there was a 6.25 and 4 unit increase in SOBQ with levalbuterol and albuterol, respectively, from baseline. A five-fold increase in SOBQ has previously been reported, which is the smallest clinically significant difference suggesting that levalbuterol may provide clinically significant improvement in dyspnea. However, these findings are limited by the open properties of the study.

It should be noted that the amount of the (R) -isomer in 2.5 mg of racemic albuterol is 1.25 mg, which is higher than the equivalent (R) -isomeric dose of 0.63 mg used in levalbuterol.This could limit our ability to find significant differences in the functional secondary outcome measures used. However, using a higher dose of racemic albuterol, we injected more of the (S) -isomer, which should amplify any (S) -isomeric difference in accompanying airway inflammation, if present. At this higher dose of albuterol, no increase in airway inflammation as measured by FeNO was found.

Our study had some limitations.The study subjects’ baseline FeNO levels were higher than we expected. This may have limited the sensitivity of the study. In addition, the small sample size can limit our ability to detect differences in FeNO levels, if any. In addition, patients were not blinded to treatment groups, which may have influenced the reporting of effort or related interventions such as walking or reporting signs of symptoms. However, this should not affect the original FeNO efficiency.Most of our subjects had relatively mild disease, which may have limited our ability to detect clinically significant differences in the secondary outcomes that were measured. Finally, the duration of each therapy may not be long enough to induce a significant change in airway inflammation that can be detected by FeNO.

Prospects for improved therapy for COPD with levalbuterol have been discussed previously (Costello, 1999). Despite the theoretical benefits, there have been several studies investigating the potential benefits of levalbuterol in the treatment of COPD.In a study by Truitt and colleagues (2003), levalbuterol demonstrated a clinical and economic advantage over racemic albuterol in the treatment of hospitalized patients with COPD and asthma, although the significance of this finding has been questioned (Hendeles 2003). Another study by Dutta et al (2003) found no benefit of using levalbuterol over conventional single-dose nebulized bronchodilators for the necessary treatment in stable COPD.

In conclusion, our study found no evidence of an increase in airway inflammation with racemic albuterol compared to levalbuterol as determined by FeNO measurement. In addition, there were no significant differences between levalbuterol and racemic albuterol in the secondary outcomes that were measured. Overall, levalbuterol does not appear to be more beneficial than racemic albuterol for the treatment of COPD. Without clear benefits, the routine use of levalbuterol for the treatment of COPD is not currently recommended.Further studies with larger numbers of subjects and a longer treatment period are needed to confirm these results.
