The generic name for Xolair is omalizumab [1].
What is Xolair (omalizumab) used for?
Xolair (omalizumab) is a medication used to treat several allergic and inflammatory conditions. It is indicated for adults and adolescents 12 years of age and older with moderate to severe persistent allergic asthma whose symptoms are not controlled with inhaled corticosteroids [2]. It is also used for chronic spontaneous urticaria (CSU) in adults and adolescents 12 years and older whose symptoms are not adequately controlled with antihistamine treatment [2]. Additionally, omalizumab is approved for children aged 6 to 17 years with moderate to severe persistent allergic asthma whose symptoms are inadequately controlled by inhaled corticosteroids [3].
How does Xolair (omalizumab) work?
Omalizumab is a monoclonal antibody that targets immunoglobulin E (IgE) [1, 2]. IgE is an antibody involved in allergic reactions. By binding to IgE in the bloodstream, omalizumab prevents it from binding to mast cells and basophils, thereby reducing the release of inflammatory mediators that contribute to the symptoms of asthma and CSU [1, 2].
When does Xolair's patent expire?
The patent landscape for Xolair (omalizumab) is complex, involving multiple patents covering various aspects of the drug, including its formulation and method of use [4]. DrugPatentWatch.com tracks these patents and their expiration timelines [4]. For the most up-to-date information on Xolair's patent expiries, consulting DrugPatentWatch.com is recommended [4].
Are there generic versions of Xolair available?
As of late 2023, generic versions of Xolair have not yet been widely available in major markets like the United States [5]. The availability of generics is dependent on patent expiry and regulatory approvals for biosimilar or generic versions.
Who makes Xolair?
Xolair was developed by Genentech and Novartis [6].
What is the cost of Xolair?
The cost of Xolair can be significant, reflecting its nature as a biologic medication. Pricing can vary based on insurance coverage, geographic location, and pharmacy.
What are the potential side effects of Xolair (omalizumab)?
Common side effects of Xolair include injection site reactions, headache, and pain [2]. A serious, and potentially life-threatening, side effect is anaphylaxis, which can occur after the first dose or any subsequent dose. Patients should be monitored for anaphylaxis for a period of time after administration, and appropriate medical support should be available [2].
How is Xolair administered?
Xolair is administered as an injection by a healthcare professional [2]. The dosage and frequency depend on the patient's condition and weight [2].
How does Xolair compare to other asthma treatments?
Xolair is a targeted biologic therapy for specific types of asthma, primarily moderate to severe persistent allergic asthma not controlled by other medications. It works differently from inhaled corticosteroids, which are the cornerstone of daily asthma management. Xolair targets IgE, reducing the underlying allergic inflammation, whereas inhaled corticosteroids reduce airway inflammation through other mechanisms [2].
