Relvar Ellipta is a medication designed to help manage asthma and chronic obstructive pulmonary disease (COPD). This inhaler contains two active ingredients, fluticasone furoate (an anti-inflammatory corticosteroid) and vilanterol (a long-acting beta agonist), which work together to reduce inflammation in your airways and help you breathe more easily. Relvar Ellipta is suitable for adults and adolescents with asthma or COPD that is not well controlled with a regular inhaler.
