Uses
DULERA is indicated for the treatment of asthma in patients 12 years of age and older.
Long-acting beta2-adrenergic agonists, such as formoterol, one of the active ingredients in DULERA, increase the risk of asthma-related death. Available data from controlled clinical trials suggest that LABA increase the risk of asthma-related hospitalization in pediatric and adolescent patients [see Warnings and Precautions (5.1)]. Therefore, when treating patients with asthma, DULERA should only be used for patients not adequately controlled on a long-term asthma control medication, such as an inhaled corticosteroid or whose disease severity clearly warrants initiation of treatment with both an inhaled corticosteroid and LABA. Once asthma control is achieved and maintained, assess the patient at regular intervals and step down therapy (e.g., discontinue DULERA) if possible without loss of asthma control, and maintain the patient on a long-term asthma control medication, such as an inhaled corticosteroid. Do not use DULERA for patients whose asthma is adequately controlled on low or medium dose inhaled corticosteroids.
Important Limitation of Use
- DULERA is NOT indicated for the relief of acute bronchospasm.

Other Information
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 C27H30Cl2O6, 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 beta2-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 (C19H24N2O4)2•C4H4O4•2H2O. 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.
Each DULERA 100 mcg/5 mcg and 200 mcg/5 mcg is a hydrofluoroalkane (HFA-227) 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 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 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.

2.1 GeneralDULERA should be administered only by the orally inhaled route (see Patient Instructions for Use in the Medication Guide). After each dose, the patient should be advised to rinse his/her mouth with water without swallowing.
The cap from the mouthpiece of the actuator should be removed before using DULERA.
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.
The DULERA canister should only be used with the DULERA actuator. The DULERA actuator should not be used with any other inhalation drug product. Actuators from other products should not be used with the DULERA canister.
2.2 DosingDULERA should be administered as two inhalations twice daily every day (morning and evening) by the orally inhaled route.
Shake well prior to each inhalation.
The recommended starting dosages for DULERA treatment are based on prior asthma therapy.
Table 1: Recommended Dosages for DULERA Previous Therapy Recommended Dose Maximum Recommended Daily Dose Inhaled medium dose corticosteroids DULERA 100 mcg/5 mcg, 2 inhalations twice daily 400 mcg/20 mcg Inhaled high dose corticosteroids DULERA 200 mcg/5 mcg, 2 inhalations twice daily 800 mcg/20 mcgThe maximum daily recommended dose is two inhalations of DULERA 200 mcg/5 mcg twice daily. Do not use more than two inhalations twice daily of the prescribed strength of DULERA as some patients are more likely to experience adverse effects with higher doses of formoterol. If symptoms arise between doses, an inhaled short-acting beta2-agonist should be taken for immediate relief.
If a previously effective dosage regimen of DULERA fails to provide adequate control of asthma, the therapeutic regimen should be re-evaluated and additional therapeutic options, e.g., replacing the current strength of DULERA with a higher strength, adding additional inhaled corticosteroid, or initiating oral corticosteroids, should be considered.
The maximum benefit may not be achieved for 1 week or longer after beginning treatment. Individual patients may experience a variable time to onset and degree of symptom relief. For patients ≥12 years of age who do not respond adequately after 2 weeks of therapy, higher strength may provide additional asthma control.
