Fluticasone Formoterol is a corticosteroid which has glucocorticoid activities. It uses a fluorocarbothioate ester linkage at the 17 carbon position. It has powerful vasoconstrictive and anti-inflammatory effects, thus, diminishes the symptoms, enhances lung function and avoids asthma exacerbations.
Formoterol is a long-acting specific beta 2 adrenoceptor agonist. It loosens up bronchial smooth muscles by incitement of adenyl cyclase, thus expanding cyclic-3′- 5′- adenosine monophosphate (cAMP) levels.
