Vilanterol is a long-acting beta-agonist (LABA) medication primarily used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the airways, making it easier to breathe. Vilanterol is often combined with other medications, such as fluticasone, to enhance its effectiveness. This medication is typically administered through an inhaler, allowing for direct delivery to the lungs. Vilanterol is designed for once-daily use, providing extended relief from symptoms. It is important for patients to follow their healthcare provider's instructions when using this medication to ensure optimal results.
