What is Trelegy Ellipta?
Trelegy Ellipta is a daily inhaler that you’ll use every day to manage symptoms of asthma. It contains three different active ingredients that work to prevent asthma symptoms.
One is a corticosteroid, which helps to ease swelling and inflammation in your lungs, and the other two are bronchodilators, which relax the muscles around your airways. This should help to ease asthma symptoms and prevent flare ups.
What is the active ingredient in Trelegy Ellipta?
Trelegy Ellipta contains three active ingredients. The first is umeclidinium, which is a type of long-acting-muscarinic-antagonist (or LAMA for short), which are also known as anticholinergics. The next is vilanterol, a long-acting-beta-2 agonist, also known as a LABA. Lastly there’s fluticasone furoate, a corticosteroid (which are different from anabolic steroids) used to manage inflammation.
How does Trelegy Ellipta work?
Trelegy Ellipta works in a couple of different ways to manage asthma symptoms. Umeclidinium is a LAMA, which is a type of bronchodilator. It blocks receptors known as muscarinic receptors, which are responsible for contracting your muscles. This relaxes the smooth muscle around your airways, helping keep them open to make breathing easier.[1]
Vilanterol is another type of bronchodilator that has a similar effect to umeclidinium, but works in a slightly different way. It binds to beta-2-adrenoceptors on the smooth muscle around your airways, causing them to relax and widen.[2]
Lastly there’s fluticasone furoate, an inhaled corticosteroid. It targets and reduces swelling in your airways and lungs by decreasing levels of inflammatory cells, and constricting blood vessels so less of these cells reach your airways.[3] This should help to manage and prevent asthma symptoms in the long-term.
How do Trelegy Ellipta doses work?
Trelegy Ellipta inhalers come in two dosages. The first contains 100 mcg of fluticasone furoate, 62.5 mcg of umeclidinium, and 25 mcg of vilanterol per actuation, and the second contains 200 mcg of fluticasone furoate, 62.5 mcg of umeclidinium, and 25 mcg of vilanterol per actuation. These doses are frequently written as 100/62.5/25 and 200/62.5/25 respectively.
