Qvar vs Pulmicort
Introduction
For patients with asthma or other types of chronic obstructive pulmonary diseases (COPD), certain drugs that alter the inflammation in the airways can help manage breathing difficulties and control symptoms. Qvar and Pulmicort are two such drugs frequently prescribed for these conditions. Both are corticosteroids, which reduce inflammation in the airways, making it easier to breathe. Qvar contains beclomethasone dipropionate, a synthetic steroid known for its potent anti-inflammatory action. On the contrary, Pulmicort contains budesonide - another synthetic steroid but one that also has high glucocorticoid activity and weak mineralocorticoid activity. While they have similar goals – to ease breathing by reducing inflammation – their differences lie in specific actions due to their active ingredients.
What is Qvar?
Beclomethasone (the generic name for Qvar) was one of the first inhaled corticosteroids to be developed and has been used since the 1970s. It is a synthetic glucocorticoid, which works by reducing inflammation in the lungs, making it easier for individuals with asthma to breathe. Beclomethasone reduces inflammation by inhibiting multiple types of immune cells and decreasing production of pro-inflammatory cytokines.
On another hand, Budesonide (the generic name for Pulmicort) is also an inhaled corticosteroid but came into use more recently than Beclomethasone. It shares many similarities with Beclomethasone as it also works through reducing lung inflammation; however, its effects are more potent per microgram compared to beclomethasone due to fewer systemic side effects owing to extensive hepatic first-pass metabolism.
Both medications are commonly prescribed as long-term treatments for chronic obstructive pulmonary disease (COPD) or asthma where they help control symptoms and improve lung function. However, their side effect profiles may differ slightly due to differences in their formulation and delivery mechanisms.
What conditions is Qvar approved to treat?
Qvar and Pulmicort are both approved for the management of asthma symptoms:
- Qvar is a maintenance treatment for the prevention and control of asthma in patients aged 5 years or older.
- Pulmicort, on the other hand, is used as a long-term medication to prevent breathing problems caused by asthma in adults and children who are at least six years old. It's also indicated for use in younger children from 12 months to 8 years under certain circumstances.
How does Qvar help with these illnesses?
Qvar is a medication designed to manage asthma by reducing inflammation in the bronchi of the lungs. It does this through its active ingredient, beclomethasone dipropionate, which belongs to a group of medicines known as corticosteroids. Corticosteroids work by decreasing inflammation and swelling in the airways, making it easier for patients with asthma to breathe. By preventing inflammation and swelling, Qvar can help reduce the frequency and severity of asthma attacks.
Pulmicort works similarly; however, it utilizes a different corticosteroid - budesonide. Both drugs are considered inhaled corticosteroids (ICS) and are among first-line treatments for managing persistent asthma symptoms due to their effectiveness at controlling chronic airway inflammation.
However, they differ slightly in terms of potency per microgram dose - Pulmicort (budesonide) is approximately twice as potent as Qvar (beclomethasone). This means that if you were taking 100mcg of Qvar per day, your equivalent dosage if switching to Pulmicort would be closer to 50mcg per day.
It's important that individuals understand both options so they can collaborate with their healthcare provider on a treatment plan that best suits their needs.
What is Pulmicort?
Pulmicort is a brand name for budesonide, which is a corticosteroid that functions by reducing inflammation in the airways. By doing so, it can help manage symptoms of asthma and chronic obstructive pulmonary disease (COPD). Budesonide was initially approved by the FDA in 1994. As Pulmicort does not work as a bronchodilator, it doesn't directly relax tightened muscles around your airways; instead its role lies mostly in long-term maintenance and prevention of asthma symptoms. This different mechanism means that Pulmicort's side-effect profile differs from bronchodilators' like Qvar; specifically, it may cause oral thrush and voice changes rather than tremors or nervousness often seen with bronchodilators. The effects on managing inflammation can be particularly beneficial for patients who need regular control over their respiratory conditions such as severe persistent asthma or COPD.
What conditions is Pulmicort approved to treat?
Pulmicort is an inhaled corticosteroid medication that is approved for the treatment and management of:
- Chronic obstructive pulmonary disease (COPD)
- Asthma, including prevention of asthma symptoms and as a maintenance therapy This drug works by reducing inflammation in the airways to improve breathing. It's important to note that Pulmicort doesn't work immediately and should not be used for sudden attacks of breathlessness.
How does Pulmicort help with these illnesses?
Budesonide, the active compound in Pulmicort, is a corticosteroid which acts as an anti-inflammatory agent. It plays a critical role in managing chronic respiratory diseases such as asthma by reducing inflammation and swelling in the airways, thus improving breathing capacity and reducing the frequency or severity of asthma attacks. Unlike Qvar which contains beclomethasone, another type of corticosteroid with similar functions but different potency, Pulmicort delivers budesonide directly to the lungs where it can exert its maximum therapeutic effect without significant systemic side effects. Its action on inflammatory cells like eosinophils and mast cells helps to control immune responses that trigger asthma symptoms. Owing to its safety profile and effectiveness for long-term management of persistent asthma, Pulmicort may be prescribed when patients do not respond well enough to other "standard" inhaler medications (such as those containing salbutamol), or it could be used concurrently with them.
How effective are both Qvar and Pulmicort?
Both beclomethasone dipropionate (Qvar) and budesonide (Pulmicort) have well-established histories of successfully treating patients with asthma, and they were initially approved by the FDA only a few years apart. Since they act on different corticosteroid receptors, they may be prescribed under different circumstances. The effectiveness of Qvar and Pulmicort in alleviating asthma was directly studied in multiple clinical trials; both drugs exhibited similar efficacy in managing symptoms of asthma as well as similar safety profiles. In these studies, none of the different metrics used to measure efficacy in treating asthma differed significantly between patients receiving Qvar or Pulmicort.
A 2003 review demonstrated that Qvar is effective at reducing inflammation starting from the first week of treatment, that its side effect profile is favorable over many other inhalers due to its small particle size which allows for better lung deposition while minimizing systemic absorption. Further, it has been found to decrease frequency and severity of exacerbations even at low doses.
A 2019 meta-analysis indicated that budesonide seems to be more effective than placebo in controlling chronic obstructive pulmonary disease (COPD), providing an additional use beyond its approval for asthma management. Despite this added benefit, Pulmicort is typically considered after bronchodilators because it does not directly affect airway smooth muscle tone but instead works by reducing inflammation over time which indirectly improves airflow obstruction. Significant research on its use involves Pulmicort co-prescribed alongside long-acting beta agonists so data confirming its efficacy as a stand-alone treatment are less robust than those for Qvar. Nonetheless, due to its unique pharmacology including once-daily dosing option and ability to treat COPD exacerbations effectively without an increased risk for pneumonia often seen with other steroids like fluticasone propionate gives it potentially preferred status among certain patient populations such as elderly or those prone to infections.
At what dose is Qvar typically prescribed?
Inhaled dosages of Qvar range from 40-320 mcg/day, but studies have suggested that a dosage of 40-80 mcg/day is sufficient for managing asthma in most individuals. Children and adolescents may start on a lower dose. For either population, the dosage can be increased after several weeks if there isn't sufficient control over the asthma symptoms. However, under no circumstances should the maximum daily intake exceed 640 mcg/day.

At what dose is Pulmicort typically prescribed?
Pulmicort treatment typically begins with a dosage of 180-400 mcg/day, divided into two doses for adults. Depending on the severity of the condition and patient response, the dose can be increased up to a maximum of 800 mcg/day, split into two doses. For children between ages six months and eight years old, an initial lower dose is recommended: around 100-200 mcg/day divided into two doses. If there's no sufficient response after an adequate duration at this initial dosage, it may be elevated gradually but should not exceed a daily total of 400 mcg for children. As always, individual dosages should be adapted according to each patient's disease severity and their overall response to therapy.

Contraindications for Qvar and Pulmicort?
Both Qvar and Pulmicort, along with most other inhaled corticosteroids, may cause symptoms such as hoarseness, dry mouth or throat irritation. If you notice these side effects getting worse or persistent white patches in your mouth or on your tongue appearing while using either of these medications, please seek medical attention.
Neither Qvar nor Pulmicort should be taken if you are already taking certain types of antifungal medication (such as itraconazole) due to potential adverse interactions. Always let your physician know any medications – prescription, over-the-counter or herbal supplements – that you're currently taking; some will require a period of time to clear from the system to prevent dangerous interactions with Qvar and Pulmicort.
Also bear in mind that both drugs can potentially lower the body's ability to fight off infections. Avoid exposure to people who have infectious diseases like chickenpox and measles until they have recovered. It is strongly recommended for patients on long-term therapy with either drug to receive vaccinations against common illnesses under their doctors' guidance.
How much do Qvar and Pulmicort cost?
For the brand name versions of these drugs:
- The price of one Qvar Redihaler (80 mcg) averages around $200, which works out to approximately $6.67/day if you are taking two inhalations daily.
- The price of one Pulmicort Flexhaler (180 mcg) is about $250, working out to roughly $8.33/day for a typical dose of two inhalations per day.
Thus, if you require the standard dosage for asthma treatment (i.e., 2 inhalations daily), then brand-name Qvar can be less expensive on a per-day treatment basis. However, cost should not be your primary consideration in determining which medication is right for you; medical effectiveness and potential side effects should also be taken into account.
As it stands currently, there are no generic equivalents available for either Qvar or Pulmicort in the U.S., so costs remain relatively higher compared to other medications that have generic versions.
Popularity of Qvar and Pulmicort
Beclomethasone dipropionate, available under the brand name Qvar among others, was estimated to have been prescribed to about 1.6 million people in the US in 2020. Beclomethasone accounted for just over 10% of corticosteroid inhaler prescriptions in the US. It appears to be one of the most common "inhaled" corticosteroids (not classified as a long-acting beta agonist or other broad class of asthma medications). The use of Qvar has seen an overall increase since its introduction.
Budesonide, including brand versions such as Pulmicort, was prescribed to approximately 2.9 million individuals in the USA during the same year. Within America, budesonide constitutes around 20% of all corticosteroid inhaler prescriptions and nearly 10% of overall asthma medication prescriptions. The prevalence rate of budesonide has remained relatively steady throughout the past decade.
Conclusion
Both Qvar (beclomethasone) and Pulmicort (budesonide) have proven their efficacy in managing asthma symptoms over years of use. Both medications belong to the class of corticosteroids, which work by reducing inflammation in the lungs. They may be used together under careful medical supervision but are usually not prescribed simultaneously due to similar mechanisms of action.
While both drugs aim at preventing asthma attacks, they differ in their delivery methods and dosage strengths. Qvar is a metered-dose inhaler that delivers medication directly into the airways, whereas Pulmicort is often administered via a nebulizer or as a dry powder inhaler depending on patient needs and age.
Generic versions are available for both medications offering potential cost savings for patients paying out-of-pocket. It's important to note that these preventative treatments require consistent use over time before maximum benefits can be observed.
Side effects between the two drugs are common including oral thrush, hoarseness, coughing, and throat irritation; however, with proper technique and mouth rinsing post-inhalation these side effects can be minimized. Patients must monitor their breathing carefully when starting treatment with either drug and seek immediate medical help if asthma symptoms worsen significantly or acute attacks occur frequently.
