ASMANEX HFA is a metered dose inhaler for oral inhalation only, consisting of 50 mcg, 100 mcg, or 200 mcg of mometasone furoate per actuation. Mometasone furoate, the active component of ASMANEX HFA, is a corticosteroid having the chemical name 9,21-dichloro-11(Beta),17-dihydroxy-16 (alpha)-methylpregna-1,4-diene-3,20-dione 17-(2-furoate) with the following chemical structure: Mometasone furoate is a white powder with an empirical formula of C 27 H 30 Cl 2 O 6 , and molecular weight 521.44. It is practically insoluble in water; slightly soluble in methanol, ethanol, and isopropanol; soluble in acetone. ASMANEX HFA 50 mcg, 100 mcg, and 200 mcg are each formulated as a hydrofluoroalkane (HFA-227: 1,1,1,2,3,3,3-heptafluoropropane) propelled pressurized metered dose inhaler containing sufficient amount of drug for 120 actuations [see How Supplied/Storage and Handling (16) ] . After priming, each actuation of the inhaler delivers 60, 115, or 225 mcg of mometasone furoate in 69.6 mg of suspension from the valve and delivers 50, 100, or 200 mcg of mometasone furoate from the actuator. The actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between actuation of the device and inspiration through the delivery system. ASMANEX HFA also contains ethanol as a cosolvent and oleic acid as a surfactant. ASMANEX HFA should be primed before using for the first time by releasing 4 test sprays into the air, away from the face, shaking well before each spray. In cases where the inhaler has not been used for more than 5 days, prime the inhaler again by releasing 4 test sprays into the air, away from the face, shaking well before each spray.
