Qvar vs Asmanex
Introduction
For patients with asthma or other types of chronic obstructive pulmonary diseases (COPD), certain drugs that control the inflammation in the lungs can help in reducing symptoms and improving lung function. Qvar and Asmanex are two such drugs that are prescribed for these conditions. They each have different modes of action, but both work to decrease inflammation in the airways.
Qvar is a beclomethasone dipropionate inhaler, which reduces inflammation by suppressing migration of inflammatory cells and reversing capillary permeability. On the other hand, Asmanex contains mometasone furoate, another corticosteroid medication that helps reduce airway swelling and inflammation. Both medications should not be used as rescue inhalers during an asthma attack; they are intended for long-term management of symptoms.
What is Qvar?
Beclomethasone dipropionate (the generic name for Qvar) was one of the first inhaled corticosteroids used to manage asthma. It received FDA approval in 2000. Qvar works by reducing inflammation and swelling in the airways, allowing for easier breathing. It is prescribed primarily as a long-term treatment option for preventing asthma attacks rather than an immediate relief medication. Beclomethasone has a targeted effect on lung tissue with minimal systemic effects, which results in it having fewer side effects compared to other corticosteroids that may have more significant impacts on the body.
On the other hand, Mometasone furoate (the generic name for Asmanex) is another type of inhaled corticosteroid but was approved later by the FDA, in 2004. Similar to Qvar, Asmanex also reduces inflammation and swelling within the airways providing better control over symptoms related to asthma — however it's typically taken once daily due its long-lasting effect.
What conditions is Qvar approved to treat?
Qvar is approved for the management and long-term control of asthma as follows:
- Maintenance treatment in patients with persistent asthma, including those who require oral corticosteroid therapy
- Prophylactic therapy in children aged 5 years or older
- As an adjunctive therapy for adults and adolescents aged 12 years or older who are not adequately controlled on other asthma-controller medications.
How does Qvar help with these illnesses?
Qvar and Asmanex are both medications that help manage the symptoms of asthma by reducing inflammation in the airways. They do this by delivering corticosteroids directly to the lungs, which suppresses immune response thereby reducing swelling and production of mucus.
In particular, Qvar contains beclomethasone dipropionate, a synthetic corticosteroid with potent anti-inflammatory effects. It works by inhibiting certain cells and chemicals involved in immune responses that cause inflammation.
Asmanex, on the other hand, contains mometasone furoate – another synthetic corticosteroid with strong anti-inflammatory activity. Mometasone also reduces inflammation but through slightly different mechanisms.
It is thought that individuals with asthma have hypersensitive airways prone to inflammatory reactions when exposed to certain triggers like allergens or exercise. Therefore, by decreasing inflammation in the lungs, both Qvar and Asmanex can limit negative respiratory symptoms associated with asthma and help patients manage their condition effectively.
What is Asmanex?
Asmanex is a brand name for mometasone, which is a corticosteroid and acts by reducing inflammation in the lungs. It achieves this by inhibiting inflammatory cells like eosinophils and reducing production of certain immune responses that can cause inflammation. Mometasone was first approved by the FDA in 1987. As it's not a bronchodilator, it doesn't relax or open up airways directly but rather reduces swelling within them over time. This means its side effect profile is different than bronchodilators, as it won't typically result in an immediate relief during an asthma attack nor does it cause common side effects associated with such medications such as jitteriness or palpitations (common side effects of bronchodilators like Albuterol). Its effects on reducing lung inflammation can be beneficial for managing chronic conditions like asthma, especially in patients who aren’t getting sufficient control from “typical” quick-relief inhalers alone.
What conditions is Asmanex approved to treat?
Asmanex, a corticosteroid inhaler, is approved for the treatment of:
- Chronic asthma
- Nighttime asthma symptoms
It's important to note that Asmanex should not be used as a rescue inhaler during an acute asthma attack. Rather, it is designed for regular use to control and prevent asthma symptoms.
How does Asmanex help with these illnesses?
Corticosteroids, like those found in Asmanex, play an important role in the body's response to inflammation and allergies. They reduce inflammation and immune responses by suppressing the activity of certain immune cells and chemicals involved in allergic reactions. Asmanex works by delivering a corticosteroid called mometasone directly to the lungs, thereby reducing asthma symptoms such as wheezing, shortness of breath, and chest tightness. Its action on inflammatory processes may also alleviate other allergy-related conditions. While both Qvar and Asmanex deliver steroids directly to the lungs for maximum effect with minimal systemic side effects, some patients might prefer Asmanex due to its active component being less likely to cause oral thrush - a common side effect associated with inhalable steroids. Furthermore, it is often prescribed when a patient does not respond well or cannot tolerate other "typical" inhaled corticosteroids (such as Qvar), or it may be combined with them for enhanced effectiveness.
How effective are both Qvar and Asmanex?
Both Qvar (beclomethasone) and Asmanex (mometasone) are established corticosteroids used in the management of asthma, with both having been approved by the FDA within a few years of each other. As they operate on similar mechanisms to reduce inflammation in airways, their prescribing circumstances are often alike. A direct comparative study conducted in 2005 found no significant differences between beclomethasone and mometasone concerning efficacy in controlling asthma symptoms or safety profiles.
A 2010 review of meta-analysis reports on Qvar showed that it is effective from as soon as one week into treatment at reducing inflammation and relieving symptoms associated with chronic asthma. Its side effect profile was found to be favorable over many other corticosteroids, being well-tolerated even among children and elderly populations. This same report noted that Qvar has become widely prescribed around the world for managing persistent asthma due to its consistent effectiveness.
A 2017 review and meta-analysis indicated that Asmanex seems more potent than placebo at treating severe asthma, showing comparable efficacy to other common corticosteroids. Despite this potency, Asmanex is often considered a second-line treatment option after short-acting beta agonists or alongside them if needed for better control of severe cases. Research involving standalone use of Asmanex is less robust compared to data supporting its co-prescription with long-term bronchodilators like salmeterol or formoterol which enhance its effects significantly; however corroborative evidence remains limited. As such, despite their analogous pharmacology, choice between Qvar and Asmanex would likely depend more on individual patient factors rather than major differences between these medications themselves.
At what dose is Qvar typically prescribed?
Inhaled dosages of Qvar range from 40-320 mcg/day, but research suggests that for most people with asthma, a dose of 80 mcg/day is sufficient. Children and adolescents may start on a lower dosage tailored to their body weight and severity of symptoms. The dosage can be increased after a few weeks if there is no response, under medical supervision. However, the maximum recommended daily dose should not exceed 320 mcg/day in any case.

At what dose is Asmanex typically prescribed?
Asmanex treatment is usually initiated at a dosage of 220 mcg/day for adults and adolescents over the age of 12. The dose can then be increased to a maximum of 440 mcg/day, divided into two doses, spaced about 12 hours apart. However, if there is no adequate response to therapy after around two weeks at this maximal level, your healthcare provider may re-evaluate the regimen and consider additional therapeutic options. For children between ages four to eleven years old, it's typically started with one inhalation (110 mcg) once daily in the evening. As with any medication regime, adherence and proper use are critical for achieving optimal results from Asmanex.
What are the most common side effects for Qvar?
Common side effects of Qvar can include:
- Oral thrush (a fungal infection in the mouth)
- Changes in voice or hoarseness
- Cough
- Headache
- Throat irritation and pain
While Asmanex may cause similar side effects, it might also lead to:
- Upper respiratory tract infection
- Sinusitis
- Fatigue
- Muscle, bone, back pain
- Indigestion
It is crucial to know that everyone's reaction to medication varies. If any of these side effects persist or worsen after using either Qvar or Asmanex, you should seek medical attention immediately.
Are there any potential serious side effects for Qvar?
While both Qvar and Asmanex are generally safe for managing asthma, they may cause some serious side effects in rare cases. For Qvar, these could include:
- Severe allergic reactions: hives; difficulty breathing or swallowing; swelling of the face, lips, tongue or throat.
- Vision changes: blurred vision, tunnel vision, seeing halos around lights.
- Signs of infection: fever with chills; body aches; flu-like symptoms
- Changes in heartbeat rhythm - unusually fast or irregular heartbeats.
- Increased anxiety and restlessness.
For Asmanex:
- Unusual signs of allergy such as skin rash, itching or hives on the skin; swelling of the face, lips, tongue or other parts of the body which may cause difficulty in swallowing/breathing.
In addition to these specific side-effects related to each drug separately there could also be general symptoms that might indicate an adverse reaction to either medication including sudden weight gain (especially around your midsection); bone pain; muscle weakness/limp feeling. If you experience any unusual discomforts after starting either medication it is advisable to consult your healthcare provider immediately.
What are the most common side effects for Asmanex?
Asmanex, an inhaled steroid used to treat asthma, does have potential side effects. These may include:
- Mild cough or hoarseness
- Dry mouth and throat
- Changes in taste
- Headache or dizziness
- Nausea, vomiting, upset stomach
- Rash or itching skin on the face and body
- Difficulty sleeping (insomnia)
- Fatigue or feeling of nervousness and restlessness -Stuffy nose and sinus pain
It's important to note that while these side effects are possible with Asmanex use, they do not occur in all patients. Most people tolerate this medication well without experiencing significant discomfort. If you're considering Asmanex for your asthma management plan, discuss these potential side effects with your healthcare provider so you can make an informed decision.
Are there any potential serious side effects for Asmanex?
Asmanex, like all medications, may cause certain side effects. It is critical to monitor for signs of an allergic reaction, which could include hives; itching; fever; swollen glands; difficulty breathing or swelling in your face or throat. Also watch out for vision problems such as blurred vision or seeing halos around lights. Other potential issues might involve changes in mood or behavior that seem unusual, including feelings of extreme happiness or irritability and sleeping difficulties. In rare cases, Asmanex can also lead to irregular heartbeats. If you experience any severe symptoms while using Asmanex—or notice any significant changes—it's crucial to seek medical attention immediately.
Contraindications for Qvar and Asmanex?
Like all corticosteroids, Qvar and Asmanex might induce some unpleasant side effects. If you notice any signs of allergic reaction, like hives, difficulty breathing or swelling in the face, lips or throat after taking these medications, seek immediate medical assistance.
Qvar and Asmanex can't be used if you are dealing with an active infection caused by bacteria, fungi or virus. Always inform your physician about your current health status; infections will need to be properly treated before starting a course of either medication to avoid further complications.
These medications may cause eye problems such as glaucoma or cataracts. It's advised that regular eye examinations are conducted while using either of these drugs. Furthermore, long-term use may weaken the immune system making it harder for you to fight off infections.
It is highly advisable not to stop taking these medicines abruptly without consulting your doctor first as doing so could exacerbate asthma symptoms. Instead there should be a gradual reduction in dose under the supervision of a healthcare professional.
Lastly remember that both Qvar and Asmanex should only supplement other asthma control treatments prescribed by your doctor but should never replace fast-acting inhalers during an acute attack.
How much do Qvar and Asmanex cost?
For the brand name versions of these drugs:
- The price of 1 inhaler (10.6g) of Qvar 80 mcg is around $200, which works out to approximately $7/day at a common dosage.
- The price for Asmanex Twisthaler (60 doses per inhaler) varies from about $250 to $300 based on the dosage strength, working out to roughly $4–$5/day.
Thus, if you are using a typical daily dose, then brand-name Asmanex is less expensive on a per-day treatment basis than Qvar. However, cost should not be your primary consideration in determining which of these asthma medications is right for you.
Currently there are no generic versions available for either Qvar or Asmanex that could potentially lower costs. It's important to consult with your healthcare provider and consider factors such as efficacy, potential side effects and how well each drug controls your symptoms when choosing between them.
Popularity of Qvar and Asmanex
Beclomethasone dipropionate, commonly known as Qvar, is an inhaled corticosteroid that was prescribed to approximately 1.5 million patients in the United States in 2020. It accounted for around 8% of all prescriptions for inhaled corticosteroids used predominantly for long-term control of asthma symptoms. The prevalence rate of Qvar has been somewhat steady since its introduction.
Mometasone furoate, also known by the brand name Asmanex, was prescribed to about 2 million people in the USA during the same period. In terms of overall inhaler prescriptions used primarily for asthma management, this drug accounts for just over 10%. Its popularity has seen a slight increase over recent years due to its effective control and reduced side effects compared to other medications within this category.
Conclusion
Both Qvar (beclomethasone) and Asmanex (mometasone) are inhaled corticosteroids used for the long-term management of asthma. They work by reducing inflammation within the airways, leading to a reduction in symptoms such as wheezing and shortness of breath. Both drugs have been extensively studied, demonstrating their effectiveness compared to placebo treatments.
In some instances, these medications may be combined with other asthma drugs if patients' symptoms aren't well controlled on one drug alone. However, this should only be done under careful supervision by a healthcare provider due to potential interactions between different types of medication.
Qvar delivers smaller particle sizes than Asmanex which allows it to reach deeper into the lungs; therefore it might be prescribed more often in cases where deep lung penetration is desired or necessary. On the other hand, Asmanex Twisthaler device is usually considered easier to use especially for those having difficulty coordinating inhalation with actuation.
Both Qvar and Asmanex are available in generic form offering significant cost savings particularly for patients who must pay out-of-pocket expenses. Like most medications, there may need an adjustment period where effects may not be noticeable immediately after starting treatment.
Side effect profiles are similar among these two corticosteroids: common side effects include oral thrush and hoarseness while systemic side effects like adrenal suppression are rare but possible when used at higher doses over prolonged periods. For both drugs, patients should monitor their breathing closely — any worsening of symptoms or unexplained symptom patterns should warrant immediate medical attention.
