Dosing in kidney impairment
Use with caution in patients with these infections because of the potential for worsening of these infections. Transferring patients from systemic corticosteroids: Risk of impaired adrenal function when transferring from oral steroids. Taper patients slowly from systemic corticosteroids if transferring to DULERA. Hypercorticism and adrenal suppression: May occur with very high dosages or at the regular dosage in susceptible individuals.
DULERA should be used with caution, if at all, in patients with active or quiescent tuberculosis infection of the respiratory tract, untreated systemic fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex. 5.6 Transferring Patients from Systemic Corticosteroid Therapy Particular care is needed for patients who are transferred from systemically active corticosteroids to DULERA because deaths due to adrenal insufficiency have occurred in asthmatic patients during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids.
After withdrawal from systemic corticosteroids, a number of months are required for recovery of hypothalamic-pituitary-adrenal (HPA) function. Patients who have been previously maintained on 20 mg or more per day of prednisone (or its equivalent) may be most susceptible, particularly when their systemic corticosteroids have been almost completely withdrawn.
During this period of HPA suppression, patients may exhibit signs and symptoms of adrenal insufficiency when exposed to trauma, surgery, or infection (particularly gastroenteritis) or other conditions associated with severe electrolyte loss. Although DULERA may improve control of asthma symptoms during these episodes, in recommended doses it supplies less than normal physiological amounts of corticosteroid systemically and does NOT provide the mineralocorticoid activity necessary for coping with these emergencies.
Patients requiring systemic corticosteroids should be weaned slowly from systemic corticosteroid use after transferring to DULERA. Lung function (FEV 1 or PEF), beta-agonist use, and asthma symptoms should be carefully monitored during withdrawal of systemic corticosteroids. In addition to monitoring asthma signs and symptoms, patients should be observed for signs and symptoms of adrenal insufficiency such as fatigue, lassitude, weakness, nausea and vomiting, and hypotension.
Transfer of patients from systemic corticosteroid therapy to DULERA may unmask allergic conditions previously suppressed by the systemic corticosteroid therapy, e.g., rhinitis, conjunctivitis, eczema, arthritis, and eosinophilic conditions. During withdrawal from oral corticosteroids, some patients may experience symptoms of systemically active corticosteroid withdrawal, e.g., joint and/or muscular pain, lassitude, and depression, despite maintenance or even improvement of respiratory function. 5.7 Hypercorticism and Adrenal Suppression Mometasone furoate, a component of DULERA, will often help control asthma symptoms with less suppression of HPA function than therapeutically equivalent oral doses of prednisone.
Dosing in liver impairment
Hepatic Impairment Concentrations of mometasone furoate appear to increase with severity of hepatic impairment [see Clinical Pharmacology ] .
Preparation and administration
Administration Information Administer DULERA as two inhalations twice daily every day (morning and evening) by the orally inhaled route (see Patient Instructions for Use in the Patient Information leaflet). 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 beta 2 -agonist should be taken for immediate relief. Shake well prior to each inhalation. After each dose, advise patients to rinse their mouth with water and, without swallowing, spit out the contents to help reduce the risk of oropharyngeal candidiasis. Remove the cap from the mouthpiece of the actuator before using DULERA.
Prime DULERA 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.
Only use the DULERA canister with the DULERA actuator. Do not use the DULERA actuator with any other inhalation drug product. Do not use actuators from other products with the DULERA canister.
Drug interactions
Check mometasone furoate and formoterol against a medication listLabel text (11 paragraphs)
In clinical trials, concurrent administration of DULERA and other drugs, such as short-acting beta 2 -agonist and intranasal corticosteroids have not resulted in an increased frequency of adverse drug reactions. No formal drug interaction studies have been performed with DULERA. The drug interactions of the combination are expected to reflect those of the individual components. Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir): Use with caution. May cause increased systemic corticosteroid effects. ( 7.1 ) Adrenergic agents: Use with caution. Additional adrenergic drugs may potentiate sympathetic effects. ( 7.2 ) Xanthine derivatives and diuretics: Use with caution.
May potentiate ECG changes and/or hypokalemia. ( 7.3 , 7.4 ) MAO inhibitors, tricyclic antidepressants, macrolides, and drugs that prolong QTc interval: Use with extreme caution. May potentiate effect on the cardiovascular system. ( 7.5 ) Beta-blockers: Use with caution and only when medically necessary. May decrease effectiveness and produce severe bronchospasm. ( 7.6 ) Halogenated hydrocarbons: There is an elevated risk of arrhythmias in patients receiving concomitant anesthesia with halogenated hydrocarbons. ( 7.7 )
7.1 Inhibitors of Cytochrome P450 3A4 The main route of metabolism of corticosteroids, including mometasone furoate, a component of DULERA, is via cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4). After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally inhaled mometasone furoate increased. Concomitant administration of CYP3A4 inhibitors may inhibit the metabolism of, and increase the systemic exposure to, mometasone furoate and potentially increase the risk for systemic corticosteroid side effects.
Caution should be exercised when considering the coadministration of DULERA with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, cobicistat-containing products, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.8) and Clinical Pharmacology (12.3) ] . Consider the benefit of coadministration versus the potential risk of systemic corticosteroid effects, in which case patients should be monitored for systemic corticosteroid side effects.
7.2 Adrenergic Agents If additional adrenergic drugs are to be administered by any route, they should be used with caution because the pharmacologically predictable sympathetic effects of formoterol, a component of DULERA, may be potentiated.
7.3 Xanthine Derivatives Concomitant treatment with xanthine derivatives may potentiate any hypokalemic effect of formoterol, a component of DULERA.
7.4 Diuretics Concomitant treatment with diuretics may potentiate the possible hypokalemic effect of adrenergic agonists. The ECG changes and/or hypokalemia that may result from the administration of non-potassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of DULERA with non-potassium-sparing diuretics.
7.5 Monoamine Oxidase Inhibitors, Tricyclic Antidepressants, and Drugs Known to Prolong the QTc Interval DULERA should be administered with caution to patients being treated with monoamine oxidase inhibitors, tricyclic antidepressants, macrolides, or drugs known to prolong the QTc interval or within 2 weeks of discontinuation of such agents, because the action of formoterol, a component of DULERA, on the cardiovascular system may be potentiated by these agents. Drugs that are known to prolong the QTc interval have an increased risk of ventricular arrhythmias.
7.6 Beta-Adrenergic Receptor Antagonists Beta-adrenergic receptor antagonists (beta-blockers) and formoterol may inhibit the effect of each other when administered concurrently. Beta-blockers not only block the therapeutic effects of beta 2 -agonists, such as formoterol, a component of DULERA, but may produce severe bronchospasm in patients with asthma. Therefore, patients with asthma should not normally be treated with beta-blockers. However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-blockers in patients with asthma.
In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.
7.7 Halogenated Hydrocarbons There is an elevated risk of arrhythmias in patients receiving concomitant anesthesia with halogenated hydrocarbons.
Contraindications
Primary treatment of status asthmaticus or acute episodes of asthma requiring intensive measures. ( 4.1 ) Hypersensitivity to any of the ingredients of DULERA. ( 4.2 )
4.1 Status Asthmaticus DULERA is contraindicated in the primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required.
4.2 Hypersensitivity DULERA is contraindicated in patients with known hypersensitivity to mometasone furoate, formoterol fumarate, or any of the ingredients in DULERA [see Warnings and Precautions (5.10) ] .
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary There are no randomized clinical studies of DULERA, mometasone furoate, or formoterol fumarate in pregnant women. There are clinical considerations with the use of DULERA in pregnant women [see Clinical Considerations ] . Animal reproduction studies with DULERA are not available; however, studies are available with its individual components, mometasone furoate and formoterol fumarate.
In animal reproduction studies, subcutaneous administration of mometasone furoate to pregnant mice, rats, or rabbits caused increased fetal malformations and decreased fetal survival and growth following administration of doses that produced exposures approximately 1/3 to 8 times the maximum recommended human dose (MRHD) on a mcg/m 2 or AUC basis [see Data ] . However, experience with oral corticosteroids suggests that rodents are more prone to teratogenic effects from corticosteroid exposure than humans.
In animal reproduction studies, oral administration of formoterol fumarate to pregnant rats and rabbits caused increased fetal malformations (rats and rabbits), decreased fetal weight (rats), and increased neonatal mortality (rats) following administration of doses that produced exposures approximately 1200 to 49,000 times the MRHD on a mg/m 2 or AUC basis [see Data ] . These adverse effects generally occurred at large multiples of the MRHD when formoterol fumarate was administered by the oral route to achieve high systemic exposures. No effects were observed in a study with rats that received formoterol fumarate by the inhalation route at an exposure approximately 500 times the MRHD.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal adverse outcomes such as preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate.
Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control. Labor or delivery There are no adequate and well-controlled human studies that have studied the effects of DULERA during labor and delivery. Because of the potential for beta-agonist interference with uterine contractility, use of DULERA during labor should be…
