Qvar’s market departure has sparked numerous inquiries, and WHY.EDU.VN is here to shed light on this matter. Qvar was discontinued for business reasons, not for safety or effectiveness concerns. Delve deeper with us as we explore the circumstances surrounding its removal, alternative options, and related information. In this article, you will learn about beclomethasone dipropionate HFA, asthma medication, and inhalation aerosol.
1. Understanding Qvar and Its Uses
Qvar, known generically as beclomethasone dipropionate HFA, is an inhaled corticosteroid used for the maintenance treatment of asthma. It is designed to reduce inflammation in the lungs, thereby preventing asthma symptoms such as wheezing, coughing, and shortness of breath. Qvar was available in two strengths: Qvar 40 and Qvar 80, indicating the dosage of beclomethasone dipropionate in each inhalation.
1.1. How Qvar Works
Qvar works by delivering beclomethasone dipropionate directly to the lungs. This corticosteroid reduces inflammation by suppressing the release of substances in the body that cause inflammation. Regular use of Qvar can help control asthma symptoms, reducing the need for rescue inhalers like albuterol.
1.2. Common Uses of Qvar
Qvar was primarily prescribed for:
- Maintenance Treatment of Asthma: Regular, daily use to control and prevent asthma symptoms in adults and children over 5 years old.
- Prophylactic Therapy: Preventing asthma attacks before they occur by reducing inflammation in the airways.
- Long-Term Asthma Control: As part of a comprehensive asthma management plan, often used in conjunction with other medications.
1.3. Dosage and Administration
Qvar is administered via an inhaler, typically twice daily. The dosage depends on the severity of the asthma and the patient’s response to the medication. It is crucial to follow the prescribing doctor’s instructions and use the inhaler correctly to ensure the medication reaches the lungs effectively.
2. The Discontinuation of Qvar: Business Decisions, Not Safety Concerns
The primary reason Qvar was taken off the market was due to business decisions made by the manufacturer, Teva Pharmaceuticals, and not because of any safety or effectiveness issues. This distinction is crucial because it assures patients and healthcare providers that the medication was not harmful or ineffective.
2.1. FDA’s Determination
The Food and Drug Administration (FDA) officially determined that Qvar 40 and Qvar 80 (beclomethasone dipropionate HFA) inhalation aerosol were not withdrawn from sale for reasons of safety or effectiveness. This determination was made after reviewing available data and a citizen petition submitted by Aurolife Pharma LLC.
2.2. Business and Economic Factors
Several business and economic factors can influence a pharmaceutical company’s decision to discontinue a product:
- Profitability: If a drug is no longer profitable due to factors like generic competition, manufacturing costs, or changing market dynamics, the manufacturer may decide to discontinue it.

5.2. Long-Term Control Medications
Long-term control medications are used daily to prevent asthma symptoms. These medications work by reducing inflammation in the airways and preventing airway constriction. Common long-term control medications include:
- Inhaled Corticosteroids (ICS): These are the most common long-term control medications for asthma. They reduce inflammation in the airways and help prevent asthma symptoms.
- Combination Inhalers (ICS/LABA): These inhalers combine an inhaled corticosteroid with a long-acting beta-agonist (LABA). They provide both anti-inflammatory and bronchodilator effects.
- Leukotriene Modifiers: These oral medications block the action of leukotrienes, substances in the body that cause inflammation and airway constriction.
- Biologic Therapies: These injectable medications target specific components of the immune system involved in asthma.
- Theophylline: This older medication helps relax airway muscles and reduce inflammation.
5.3. Quick-Relief Medications
Quick-relief medications, also known as rescue medications, are used to quickly relieve asthma symptoms when they occur. These medications work by relaxing the muscles around the airways, allowing them to open up and make it easier to breathe. The most common quick-relief medication is:
- Albuterol: Albuterol is a short-acting beta-agonist (SABA) that provides quick relief of asthma symptoms. It is available as an inhaler and a nebulizer solution.
5.4. Asthma Triggers and How to Avoid Them
Asthma triggers are substances or conditions that can worsen asthma symptoms. Common asthma triggers include:
- Allergens: Allergens such as pollen, dust mites, mold, and pet dander can trigger asthma symptoms.
- Irritants: Irritants such as smoke, air pollution, and strong odors can also trigger asthma symptoms.
- Exercise: Exercise can trigger asthma symptoms in some people. This is known as exercise-induced asthma.
- Respiratory Infections: Respiratory infections such as colds and flu can worsen asthma symptoms.
- Weather Changes: Changes in weather, such as cold air or high humidity, can trigger asthma symptoms.
5.5. Creating an Asthma Action Plan
An asthma action plan is a written plan developed with your healthcare provider that outlines how to manage your asthma. The plan should include:

6. The Role of the FDA in Drug Approval and Discontinuation
The FDA plays a crucial role in regulating the pharmaceutical industry, ensuring that drugs are safe and effective before they are marketed to the public. The agency also oversees the discontinuation of drugs to protect public health.
6.1. FDA Approval Process
The FDA approval process is rigorous and involves several stages:
- Preclinical Testing: Before a drug can be tested in humans, it must undergo preclinical testing in laboratory and animal studies to assess its safety and efficacy.
- Clinical Trials: If preclinical testing is successful, the drug can proceed to clinical trials in humans. Clinical trials are conducted in three phases:
- Phase 1: Small studies to assess safety and dosage.
- Phase 2: Larger studies to evaluate efficacy and side effects.
- Phase 3: Large, randomized controlled trials to confirm efficacy and monitor side effects.
- New Drug Application (NDA): If clinical trials are successful, the drug manufacturer can submit a New Drug Application (NDA) to the FDA.
- FDA Review: The FDA reviews the NDA, including data from preclinical testing and clinical trials, to assess the drug’s safety and efficacy.
- Approval: If the FDA determines that the drug is safe and effective, it will approve the drug for marketing.
6.2. FDA’s Role in Drug Discontinuation
The FDA also plays a role in drug discontinuation. The agency can request or mandate the withdrawal of a drug from the market if it determines that the drug is unsafe or ineffective. This can occur for several reasons:
- Safety Concerns: If new data emerges suggesting that a drug has unacceptable side effects, the FDA can request or mandate its withdrawal.
- Efficacy Concerns: If a drug is found to be ineffective in treating the condition it is intended for, the FDA can request or mandate its withdrawal.
- Manufacturing Issues: If a drug manufacturer fails to meet manufacturing standards or quality control requirements, the FDA can request or mandate the drug’s withdrawal.
6.3. Post-Market Surveillance
Even after a drug is approved for marketing, the FDA continues to monitor its safety and efficacy through post-market surveillance. This involves:
- Adverse Event Reporting: Healthcare providers and consumers can report adverse events associated with a drug to the FDA.
- Post-Market Studies: The FDA can require drug manufacturers to conduct post-market studies to further assess the drug’s safety and efficacy.
- Inspections: The FDA conducts inspections of drug manufacturing facilities to ensure compliance with manufacturing standards.
6.4. Generic Drug Approval Process
The FDA also oversees the approval of generic drugs. Generic drugs are versions of brand-name drugs that have the same active ingredient, strength, dosage form, and route of administration. The generic drug approval process is streamlined compared to the brand-name drug approval process because generic drug manufacturers do not have to repeat the extensive clinical testing.
6.5. Orange Book
The FDA publishes a list of all approved drugs, including both brand-name and generic drugs, in the “Approved Drug Products With Therapeutic Equivalence Evaluations,” which is known generally as the “Orange Book.” The Orange Book also includes information on whether a drug has been discontinued from marketing for reasons other than safety or effectiveness.
