mometasone furoate and formoterol fumarate dihydrate - Generic Medications

DULERA 50 mcg/5 mcg, DULERA 100 mcg/5 mcg, and DULERA 200 mcg/5 mcg are combinations of mometasone furoate and formoterol fumarate dihydrate for oral inhalation only. One active component of DULERA is mometasone furoate, 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. One active component of DULERA is formoterol fumarate dihydrate, a racemate. Formoterol fumarate dihydrate is a selective beta 2 -adrenergic bronchodilator having the chemical name of (±)-2-hydroxy-5-[(1RS)-1-hydroxy-2-[[(1RS)-2-(4-methoxyphenyl)-1-methylethyl]-amino]ethyl]formanilide fumarate dihydrate with the following chemical structure: Formoterol fumarate dihydrate has a molecular weight of 840.9, and its empirical formula is (C 19 H 24 N 2 O 4 ) 2 •C 4 H 4 O 4 •2H 2 O. Formoterol fumarate dihydrate is a white to yellowish powder, which is freely soluble in glacial acetic acid, soluble in methanol, sparingly soluble in ethanol and isopropanol, slightly soluble in water, and practically insoluble in acetone, ethyl acetate, and diethyl ether. DULERA 50 mcg/5 mcg, 100 mcg/5 mcg, and 200 mcg/5 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 60 or 120 inhalations [see How Supplied/Storage and Handling (16) ] . After priming, each actuation of the inhaler delivers 60, 115, or 225 mcg of mometasone furoate and 5.5 mcg of formoterol fumarate dihydrate in 69.6 mg of suspension from the valve and delivers 50, 100, or 200 mcg of mometasone furoate and 5 mcg of formoterol fumarate dihydrate 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. DULERA also contains anhydrous alcohol as a cosolvent and oleic acid as a surfactant. DULERA 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.
