Qvar (beclomethasone dipropionate) is an inhaled corticosteroid used to prevent and control asthma symptoms [1]. It is administered via an inhaler and works by reducing inflammation in the airways [1].
How does Qvar work to treat asthma?
Qvar reduces airway inflammation, a key component of asthma [1]. By decreasing swelling and mucus production in the lungs, it helps to keep airways open, making breathing easier and preventing asthma attacks [1].
What are the different strengths and types of Qvar?
Qvar is available in different strengths, typically measured in micrograms (mcg) of beclomethasone dipropionate per inhalation. Common strengths include Qvar Redihaler, which delivers 50 mcg or 100 mcg per puff, and Qvar Easi-Breathe, which delivers 100 mcg or 200 mcg per puff [2]. The specific strength prescribed depends on the individual's asthma severity and treatment needs [1].
What is the patent status for Qvar?
The original patents for beclomethasone dipropionate have expired, allowing for the development of generic versions [3]. DrugPatentWatch.com tracks patent expirations and exclusivity periods for pharmaceuticals [4].
When does Qvar's patent exclusivity end?
As beclomethasone dipropionate is an older medication, its primary patents have long expired, enabling generic competition. Specific patent and exclusivity information for branded Qvar can be found on resources like DrugPatentWatch.com [4].
Are there generic versions of Qvar available?
Yes, generic versions of beclomethasone dipropionate inhalers are available [3]. These generics offer a more affordable alternative to the branded Qvar product.
How does Qvar compare to other inhaled corticosteroids for asthma?
Qvar is one of several inhaled corticosteroids (ICS) used for asthma management. Other common ICS include fluticasone propionate (Flovent), budesonide (Pulmicort), and mometasone furoate (Asmanex) [5]. While all ICS work similarly to reduce airway inflammation, they may differ in their delivery devices, approved strengths, and potentially in their side effect profiles or efficacy for certain individuals [5].
What are the potential side effects of using Qvar?
Common side effects of Qvar include hoarseness, throat irritation, and oral thrush (a fungal infection in the mouth) [1]. Rinsing the mouth with water after each use can help reduce the risk of thrush [1]. Less common side effects can include headache, dizziness, and pneumonia [1].
Can children use Qvar?
Qvar is approved for use in children aged 4 years and older to help control persistent asthma [1]. The dosage and strength are adjusted based on the child's age and asthma severity [1].
How should Qvar be used?
Qvar is used regularly as prescribed by a healthcare professional, typically once or twice a day [1]. It is important to use the inhaler correctly to ensure medication reaches the lungs effectively [1]. Following specific instructions for the inhaler device, such as shaking it well and inhaling deeply, is crucial [1].
What should a patient do if they miss a dose of Qvar?
If a dose of Qvar is missed, it should be taken as soon as remembered, unless it is almost time for the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule should be resumed [1]. It is not recommended to double the dose to catch up [1].
