Beclometasone or beclomethasone, also known as beclomethasone dipropionate, and sold under the brand name Qvar among others, is a steroid medication. [1] It is available as an inhaler, cream, pills, and nasal spray. [2] The inhaled form is used in the long-term management of asthma. [1] The cream may be used for dermatitis and psoriasis. [3] The pills have been used to treat ulcerative colitis. [4] The nasal spray is used to treat allergic rhinitis and nasal polyps. [5]
Common side effects with the inhaled form include respiratory infections, headaches, and throat inflammation. [1] Serious side effects include an increased risk of infection, cataracts, Cushing's syndrome, and severe allergic reactions. [1] Long-term use of the pill form may cause adrenal insufficiency. [4] The pills may also cause mood or personality changes. [4] The inhaled form is generally regarded as safe in pregnancy. [6] Beclometasone is mainly a glucocorticoid. [1]
Beclomethasone dipropionate was first patented in 1962 and used medically in 1972. [7] It was approved for medical use in the United States in 1976. [1] It is on the World Health Organization's List of Essential Medicines. [8] In 2021, it was the 268th most commonly prescribed medication in the United States, with more than 1 million prescriptions. [9] [10]
Common side effects with the inhaled form include respiratory infections, headaches, and throat inflammation. [1] Serious side effects include an increased risk of infection, cataracts, Cushing's syndrome, and severe allergic reactions. [1] Long-term use of the pill form may cause adrenal insufficiency. [4] The pills may also cause mood or personality changes. [4] The inhaled form is generally regarded as safe in pregnancy. [6]
Occasionally, it may cause a cough upon inhalation. Deposition on the tongue and throat may promote oral candidiasis, which appears as a white coating, possibly with irritation. [11] [12] [13] This may usually be prevented by rinsing the mouth with water after using the inhaler. Other adverse drug reaction side effects may rarely include: a smell similar to burning plastic, unpleasant taste, hoarseness or nasal congestion, pain or headache, and visual changes. Allergic reactions may occur, but rarely.
Nasal corticosteroids may be associated with central serous retinopathy. [14]
Beclometasone is mainly a glucocorticoid. [1] Glucocorticoids are corticosteroids that bind to the glucocorticoid receptor [15] that is present in almost every vertebrate animal cell. The activated glucocorticoid receptor-glucocorticoid complex up-regulates the expression of anti-inflammatory proteins in the nucleus (a process known as transactivation) and represses the expression of proinflammatory proteins in the cytosol by preventing the translocation of other transcription factors from the cytosol into the nucleus (transrepression). [16]
Glucocorticoids are part of the feedback mechanism in the immune system which reduces certain aspects of immune function, such as inflammation.
Beclometasone dipropionate is the INN modified and beclomethasone dipropionate is the USAN and former BAN. It is a prodrug of the free form, beclometasone (INN). The prodrug beclometasone is marketed in Norway and Russia. [17] [18] [19] [20] [21]
Clenil, Qvar, Cortis are brandnames for the inhalers; Beconase, Alanase, Vancenase, Qnasl for the nasal spray or aerosol.
Candidiasis is a fungal infection due to any species of the genus Candida. When it affects the mouth, in some countries it is commonly called thrush. Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. Other symptoms may include soreness and problems swallowing. When it affects the vagina, it may be referred to as a yeast infection or thrush. Signs and symptoms include genital itching, burning, and sometimes a white "cottage cheese-like" discharge from the vagina. Yeast infections of the penis are less common and typically present with an itchy rash. Very rarely, yeast infections may become invasive, spreading to other parts of the body. This may result in fevers, among other symptoms.
Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones. Two main classes of corticosteroids, glucocorticoids and mineralocorticoids, are involved in a wide range of physiological processes, including stress response, immune response, and regulation of inflammation, carbohydrate metabolism, protein catabolism, blood electrolyte levels, and behavior.
A decongestant, or nasal decongestant, is a type of pharmaceutical drug that is used to relieve nasal congestion in the upper respiratory tract. The active ingredient in most decongestants is either pseudoephedrine or phenylephrine. Intranasal corticosteroids can also be used as decongestants and antihistamines can be used to alleviate runny nose, nasal itch, and sneezing.
Prednisolone is a corticosteroid, a steroid hormone used to treat certain types of allergies, inflammatory conditions, autoimmune disorders, and cancers. Some of these conditions include adrenocortical insufficiency, high blood calcium, rheumatoid arthritis, dermatitis, eye inflammation, asthma, and multiple sclerosis. It can be taken by mouth, injected into a vein, used topically as a skin cream, or as eye drops. It differs from the similarly named prednisone in having a hydroxyl at the 11th carbon instead of a ketone.
Ipratropium bromide, sold under the trade name Atrovent among others, is a type of anticholinergic medication which is applied by different routes: inhaler, nebulizer, or nasal spray, for different reasons.
Triamcinolone is a glucocorticoid used to treat certain skin diseases, allergies, and rheumatic disorders among others. It is also used to prevent worsening of asthma and COPD. It can be taken in various ways including by mouth, injection into a muscle, and inhalation.
Nasal sprays are used to deliver medications locally in the nasal cavities or systemically. They are used locally for conditions such as nasal congestion and allergic rhinitis. In some situations, the nasal delivery route is preferred for systemic therapy because it provides an agreeable alternative to injection or pills. Substances can be assimilated extremely quickly and directly through the nose. Many pharmaceutical drugs exist as nasal sprays for systemic administration. Other applications include hormone replacement therapy, treatment of Alzheimer's disease and Parkinson's disease. Nasal sprays are seen as a more efficient way of transporting drugs with potential use in crossing the blood–brain barrier.
Salmeterol is a long-acting β2 adrenergic receptor agonist (LABA) used in the maintenance and prevention of asthma symptoms and maintenance of chronic obstructive pulmonary disease (COPD) symptoms. Symptoms of bronchospasm include shortness of breath, wheezing, coughing and chest tightness. It is also used to prevent breathing difficulties during exercise.
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.
Betamethasone is a steroid medication. It is used for a number of diseases including rheumatic disorders such as rheumatoid arthritis and systemic lupus erythematosus, skin diseases such as dermatitis and psoriasis, allergic conditions such as asthma and angioedema, preterm labor to speed the development of the baby's lungs, Crohn's disease, cancers such as leukemia, and along with fludrocortisone for adrenocortical insufficiency, among others. It can be taken by mouth, injected into a muscle, or applied to the skin, typically in cream, lotion, or liquid forms.
Fluticasone propionate, sold under the brand names Flovent and Flonase among others, is a steroid medication. When inhaled it is used for the long term management of asthma and COPD. In the nose it is used for hay fever and nasal polyps. It can also be used for mouth ulcers. It works by decreasing inflammation.
Triamcinolone acetonide, sold under the brand name Kenalog among others, is a synthetic corticosteroid medication used topically to treat various skin conditions, to relieve the discomfort of mouth sores, and by injection into joints to treat various joint conditions. It is also injected into lesions to treat inflammation in some parts of the body, particularly the skin. In nasal spray form, it is used to treat allergic rhinitis. It is used for the treatment of macular edema associated with uveitis. It is a more potent derivative of triamcinolone, and is about eight times as potent as prednisone.
Flunisolide is a corticosteroid often prescribed as treatment for allergic rhinitis. Intranasal corticosteroids are the most effective medication for controlling symptoms.
Mometasone, also known as mometasone y 3 s, is a steroid medication used to treat certain skin conditions, hay fever, and asthma. Specifically it is used to prevent rather than treat asthma attacks. It can be applied to the skin, inhaled, or used in the nose. Mometasone furoate, not mometasone, is used in medical products.
Loteprednol is a topical corticosteroid used to treat inflammations of the eye. It is marketed by Bausch and Lomb as Lotemax and Loterex.
Ciclesonide is a glucocorticoid used to treat asthma and allergic rhinitis. It is marketed under the brand names Alvesco for asthma and Omnaris, Omniair, Zetonna, and Alvesco for hay fever in the US and Canada.
Budesonide, sold under the brand name Pulmicort among others, is a medication of the corticosteroid type. It is available as an inhaler, nebulization solution, pill, nasal spray, and rectal forms. The inhaled form is used in the long-term management of asthma and chronic obstructive pulmonary disease (COPD). The nasal spray is used for allergic rhinitis and nasal polyps. The pills in a delayed release form and rectal forms may be used for inflammatory bowel disease including Crohn's disease, ulcerative colitis, and microscopic colitis.
Fluticasone furoate/umeclidinium bromide/vilanterol, sold under the brand name Trelegy Ellipta among others, is a fixed-dose combination inhaled medication that is used for the maintenance treatment of chronic obstructive pulmonary disease (COPD). The medications work in different ways: fluticasone furoate is an inhaled corticosteroid (ICS), umeclidinium is a long-acting muscarinic antagonist (LAMA), and vilanterol is a long-acting beta-agonist (LABA).
Topical glucocorticoids are the topical forms of glucocorticoids. Topical glucocorticoids are used in the treatment of many skin conditions. They provide anti-inflammatory, antimitotic, and immune-system suppressing actions through various mechanisms.
