Trelegy Ellipta is a brand name for a medication used in the treatment of chronic obstructive pulmonary disease (COPD). It is a combination inhaler that contains three active ingredients: Fluticasone furoate: This is a corticosteroid that helps to reduce inflammation in the airways, which is a common characteristic of COPD. Umeclidinium: This is an anticholinergic medication that helps to relax the muscles around the airways, making it easier for individuals with COPD to breathe.Vilanterol: This is a long/acting beta/agonist (LABA) that helps to open up the airways by relaxing the muscles surrounding them, thereby making it easier for air to flow in and out.Trelegy Ellipta is typically used once daily as an inhalation powder. It comes in a device called the Ellipta inhaler, which delivers the medication in a dry powder form. This combination medication is intended for maintenance treatment of COPD and is generally prescribed for patients who require both an inhaled corticosteroid and a long/acting bronchodilator.
