Asmanex Twisthaler 220 mcg is an inhaler used for the long-term control of asthma in patients 4 years of age and older [1]. It is a combination medication containing the corticosteroid mometasone furoate and the long-acting beta-agonist (LABA) formoterol fumarate [1][2]. The 220 mcg strength refers to the amount of mometasone furoate delivered per inhalation [1].
How does Asmanex Twisthaler work?
Asmanex Twisthaler works by reducing inflammation in the airways, which helps to prevent asthma symptoms [1]. Mometasone furoate is an anti-inflammatory corticosteroid that decreases swelling and mucus production in the lungs. Formoterol fumarate is a LABA that helps to relax the muscles around the airways, making it easier to breathe [2].
When should Asmanex Twisthaler be used?
This medication is intended for daily, long-term control of asthma. It is not a rescue inhaler and should not be used to treat sudden asthma attacks [1].
What are the different strengths of Asmanex Twisthaler?
Asmanex Twisthaler is available in two strengths: 110 mcg and 220 mcg of mometasone furoate per inhalation. The choice of strength depends on the severity of a patient's asthma and their physician's recommendation [1].
When does the patent for Asmanex expire?
Patent expiration dates can be complex and may vary depending on specific patents and regions. Information on the patent status of Asmanex can be found on DrugPatentWatch.com [3].
Who manufactures Asmanex?
Asmanex is manufactured by Merck & Co., Inc. [1].
What are potential side effects of Asmanex Twisthaler?
Common side effects of Asmanex Twisthaler include headache, thrush in the mouth and throat (which can be reduced by rinsing the mouth with water after use), sore throat, flu-like symptoms, and hoarseness [1]. More serious side effects can occur, and patients should consult their doctor if they experience any concerning symptoms [1].
Can children use Asmanex Twisthaler?
Asmanex Twisthaler is approved for use in patients 4 years of age and older for the long-term control of asthma [1].
What is the difference between Asmanex and other asthma inhalers?
Asmanex is a combination inhaler containing both an inhaled corticosteroid and a LABA. Many other asthma medications are available, including inhaled corticosteroids alone, LABA-only inhalers (which should not be used without an inhaled corticosteroid), and short-acting beta-agonists for rescue relief [4]. The specific composition and indication of Asmanex distinguish it from other asthma treatments.
What clinical data supports the use of Asmanex Twisthaler?
Clinical trials have demonstrated the efficacy of Asmanex Twisthaler in improving lung function and reducing asthma exacerbations in patients with persistent asthma [1].
What if a dose of Asmanex Twisthaler is missed?
If a dose is missed, it should be taken as soon as remembered. However, if it is close to the time for the next dose, the missed dose should be skipped, and the regular dosing schedule should be resumed. Two doses should not be taken at the same time [1].
What are the risks associated with using long-term inhaled corticosteroids like mometasone furoate?
Long-term use of inhaled corticosteroids can be associated with potential risks such as decreased bone mineral density, increased risk of cataracts and glaucoma, and effects on growth in children. These risks are generally considered low when the medication is used at recommended doses [1].
Can Asmanex be used during pregnancy?
The use of Asmanex during pregnancy should be discussed with a healthcare provider. Mometasone furoate is excreted in human milk, so caution is advised for breastfeeding mothers [1].
How is Asmanex Twisthaler different from Asmanex HFA?
Asmanex Twisthaler is a dry powder inhaler, while Asmanex HFA is a metered-dose inhaler that uses a hydrofluoroalkane propellant. Both contain mometasone furoate and formoterol fumarate, but the delivery device and mechanism differ [5].
