Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as allergic granulomatosis, is an extremely rare autoimmune condition that causes inflammation of small and medium-sized blood vessels (vasculitis) in persons with a history of airway allergic hypersensitivity (atopy).
Zafirlukast is an orally administered leukotriene receptor antagonist (LTRA) used for the chronic treatment of asthma. While zafirlukast is generally well tolerated, headaches and stomach upset often occur. Some rare side effects can occur, which can be life-threatening, such as liver failure. eosinophilic granulomatosis with polyangiitis has been associated with zafirlukast, but the relationship isn't thought to be causative. Overdoses of zafirlukast tend to be self-limiting.
Budesonide/formoterol, sold under the brand name Symbicort among others, is a fixed-dose combination medication used in the management of asthma or chronic obstructive pulmonary disease (COPD). It contains budesonide, a steroid; and formoterol, a long-acting β2-agonist (LABA). The product monograph does not support its use for sudden worsening or treatment of active bronchospasm. However, a 2020 review of the literature does support such use. It is used by breathing in the medication.
Tremelimumab, sold under the brand name Imjudo, is a fully human monoclonal antibody used for the treatment of hepatocellular carcinoma. Tremelimumab is designed to attach to and block CTLA-4, a protein that controls the activity of T cells, which are part of the immune system.
Reslizumab, sold under the brand names Cinqair and Cinqaero, is a humanized monoclonal antibody against human interleukin-5 (IL-5). Reslizumab binds specifically to IL-5, a key cytokine responsible for the differentiation, maturation, recruitment and activation of human eosinophils. By binding to human IL-5, it blocks its biological function; consequently survival and activity of eosinophils are reduced. The benefits with reslizumab are its ability to reduce the exacerbation rate and improve lung function and asthma-related quality of life in patients with severe eosinophilic asthma and with at least one previous asthma exacerbation in the preceding year. The most common side effects are increased blood creatine phosphokinase, myalgia and anaphylactic reactions.
Mepolizumab, sold under the brand name Nucala by GlaxoSmithKline, is a humanized monoclonal antibody used for the treatment of severe eosinophilic asthma, eosinophilic granulomatosis with polyangiitis, and hypereosinophilic syndrome (HES). It recognizes and blocks interleukin-5 (IL-5), a signalling protein of the immune system.
Canakinumab, sold under the brand name Ilaris, is a medication for the treatment of systemic juvenile idiopathic arthritis, active Still's disease, including adult-onset Still's disease, gout flares. It is a human monoclonal antibody targeted at interleukin-1 beta. It has no cross-reactivity with other members of the interleukin-1 family, including interleukin-1 alpha.
Lebrikizumab, sold under the brand name Ebglyss is a humanized monoclonal antibody used for the treatment of atopic dermatitis. It is an interleukin-13 antagonist. It is given by subcutaneous injection.
Siltuximab (INN), sold under the brand name Sylvant, is used for the treatment of people with multicentric Castleman's disease. It is a chimeric monoclonal antibody that binds to interleukin-6. It is an interleukin-6 (IL-6) antagonist.
Brodalumab, sold under the brand name Siliq in the US and Kyntheum in the EU, is a human monoclonal antibody designed for the treatment of inflammatory diseases.
Ixekizumab, sold under the brand name Taltz, is an injectable medication for the treatment of autoimmune diseases. Chemically, it is a form of a humanized monoclonal antibody. The substance acts by binding interleukin 17A and neutralizing it, reducing inflammation.
Tralokinumab sold under the brand names Adtralza (EU/UK) and Adbry (US) among others, is a human monoclonal antibody used for the treatment of atopic dermatitis. Tralokinumab targets the cytokine interleukin 13.
Dupilumab, sold under the brand name Dupixent, is a monoclonal antibody blocking interleukin 4 and interleukin 13, used for allergic diseases such as atopic dermatitis (eczema), asthma and nasal polyps which result in chronic sinusitis. It is also used for the treatment of eosinophilic esophagitis, prurigo nodularis and COPD.
Tildrakizumab, sold under the brand name Ilumya among others, is a monoclonal antibody designed for the treatment of immunologically mediated inflammatory disorders. It is approved for the treatment of adults with moderate-to-severe plaque psoriasis in the United States and in the European Union.
Anifrolumab, sold under the brand name Saphnelo, is a monoclonal antibody used for the treatment of systemic lupus erythematosus. It binds to the type I interferon receptor, blocking the activity of type I interferons such as interferon-α and interferon-β.
Risankizumab, sold under the brand name Skyrizi, is a humanized monoclonal antibody used for the treatment of plaque psoriasis, psoriatic arthritis, Crohn's disease, and ulcerative colitis. It is designed to target interleukin 23A (IL-23A). It is given by subcutaneous injection.
Tezepelumab, sold under the brand name Tezspire, is a human monoclonal antibody used for the treatment of asthma. Tezepelumab blocks thymic stromal lymphopoietin (TSLP), an epithelial cytokine that has been suggested to be critical in the initiation and persistence of airway inflammation.
Lirentelimab is a humanized nonfucosylated monoclonal antibody that targets sialic acid-binding Ig-like lectin 8 (SIGLEC8). In a randomized clinical trial, lirentelimab was found to improve eosinophil counts and symptoms in individuals with eosinophilic gastritis and duodenitis. Adverse reactions include infusion reactions, which are mild to moderate and typically occur following the first infusion.
Tixagevimab/cilgavimab, sold under the brand name Evusheld, is a combination of two human monoclonal antibodies, tixagevimab (AZD8895) and cilgavimab (AZD1061) targeted against the surface spike protein of SARS-CoV-2 used to prevent COVID-19. It is being developed by British-Swedish multinational pharmaceutical and biotechnology company AstraZeneca. It is co-packaged and given as two separate consecutive intramuscular injections.
An anti-asthmatic agent, also known as an anti-asthma drug, refers to a drug that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies and related hospital visits.
