Relvar Ellipta is a prescription medication used in the management and treatment of asthma and chronic obstructive pulmonary disease (COPD). It is a combination inhaler that contains two active ingredients: fluticasone furoate, a corticosteroid that reduces inflammation in the lungs, and vilanterol, a long-acting beta2-adrenergic agonist (LABA) that helps to relax the muscles around the airways in the lungs, making it easier to breathe. Relvar Ellipta is designed for once-daily use via a special inhaler device known as the Ellipta, which is specifically engineered for ease of use and to deliver a pre-measured dose of the medication directly to the lungs. It is important to note that Relvar Ellipta is not intended for the relief of acute bronchospasm or as a rescue inhaler.
