Fluticasone furoate is a trifluorinated corticosteroid that consists of 6alpha,9-difluoro-11beta,17alpha-dihydroxy-17beta-{[(fluoromethyl)sulfanyl]carbonyl}-16-methyl-3-oxoandrosta-1,4-diene bearing a 2-furoyl substituent at position 17. Used in combination with vilanterol trifenate for treatment of bronchospasm associated with chronic obstructive pulmonary disease. It has a role as an anti-allergic agent, a prodrug and an anti-asthmatic drug. It is an 11beta-hydroxy steroid, a corticosteroid, a fluorinated steroid, a steroid ester, a 2-furoate ester, a thioester and a 3-oxo-Delta(1),Delta(4)-steroid. It is functionally related to a fluticasone. It derives from a hydride of an androstane.
