Vilanterol is a long-acting beta2-adrenergic agonist used in combination with other bronchodilators for the management of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema.
Vilanterol is a selective long-acting beta2-adrenergic agonist. Its pharmacological effect is attributable to stimulation of intracellular adenylyl cyclase which catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP). Increases in cyclic AMP are associated with relaxation of bronchial smooth muscle and inhibition of release of hypersensitivity mediators from mast cells in the lungs.
Vilanterol is approved for use in several combination products such as with fluticasone furoate under the tradename Breo Ellipta, in combination with umeclidinium bromide as Anoro Ellipta, and in combination with both fluticasone furoate and umeclidinium under the tradename Trelegy Ellipta. Approved by the FDA in 2013, the use of Breo Ellipta is indicated for the long-term, once-daily maintenance treatment of airflow obstruction in patients with COPD, including chronic bronchitis and emphysema, as well as the once-daily maintenance treatment of asthma in patients aged 18 or older with reversible obstructive airways disease. Anoro Ellipta is indicated for the maintenance treatment of patients with COPD, and Trelegy Ellipta is indicated for the maintenance treatment of patients with COPD as well as the maintenance treatment of asthma in patients aged 18 years and older.
