Breyna Drug Information

• For oral inhalation only.
• Treatment of asthma in patients 12 years and older: 2 inhalations of BREYNA 80 mcg/4.5 mcg or 160 mcg/4.5 mcg twice daily. Starting dosage is based on asthma severity. ( 2.2 )
• Treatment of asthma in patients aged 6 to less than 12 years: 2 inhalations of BREYNA 80 mcg/4.5 mcg twice daily. ( 2.2 )
• Maintenance treatment in COPD: 2 inhalations of BREYNA 160 mcg/4.5 mcg twice daily. ( 2.3 ) 2.1 Administration Information BREYNA should be administered as 2 inhalations twice daily (morning and evening, approximately 12 hours apart), every day by the orally inhaled route only. After inhalation, the patient should rinse the mouth with water without swallowing. Prime BREYNA before using for the first time by releasing two test sprays into the air away from the face, shaking well for 5 seconds before each spray. In cases where the inhaler has not been used for more than 7 days or when it has been dropped, prime the inhaler again by shaking well before each spray and releasing two test sprays into the air away from the face. More frequent administration or a higher number of inhalations (more than 2 inhalations twice daily) of the prescribed strength of BREYNA is not recommended as some patients are more likely to experience adverse effects with higher doses of formoterol. Patients using BREYNA should not use additional LABA for any reason [see Warnings and Precautions (5.3 , 5.12) ] . 2.2 Asthma If asthma symptoms arise in the period between doses, an inhaled, short-acting beta 2 -agonist should be taken for immediate relief. Adult and Adolescent Patients 12 Years of Age and Older For patients 12 years of age and older, the dosage is 2 inhalations of BREYNA 80 mcg/4.5 mcg or BREYNA 160 mcg/4.5 mcg twice daily. The recommended starting dosages for BREYNA for patients 12 years of age and older are based upon patients’ asthma severity or level of control of asthma symptoms, and risk of exacerbations on current inhaled corticosteroids. The maximum recommended dosage in adult and adolescent patients 12 years and older is BREYNA 160 mcg/4.5 mcg, two inhalations twice daily. Improvement in asthma control following inhaled administration of BREYNA can occur within 15 minutes of beginning treatment, although maximum benefit may not be achieved for 2 weeks or longer after beginning treatment. Individual patients will experience a variable time to onset and degree of symptom relief. For patients who do not respond adequately to the starting dose after 1-2 weeks of therapy with BREYNA 80 mcg/4.5 mcg, replacement with BREYNA 160 mcg/4.5 mcg may provide additional asthma control. If a previously effective dosage regimen of BREYNA fails to provide adequate control of asthma, the therapeutic regimen should be re-evaluated and additional therapeutic options, (e.g., replacing the lower strength of BREYNA with the higher strength, adding additional inhaled corticosteroid, or initiating oral corticosteroids) should be considered. Pediatric Patients Aged 6 to Less than 12 Years For patients 6 to less than 12 years of age, the dosage is 2 inhalations of BREYNA 80 mcg/4.5 mcg twice daily. 2.3 Chronic Obstructive Pulmonary Disease For patients with COPD the recommended dose is BREYNA 160 mcg/4.5 mcg, two inhalations twice daily. If shortness of breath occurs in the period between doses, an inhaled, short-acting beta 2 -agonist should be taken for immediate relief.

• Glaucoma and cataracts [see Warnings and Precautions (5.15) ] Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Most common adverse reactions (incidence ≥ 3%) are:
• Asthma: nasopharyngitis, headache, upper respiratory tract infection, pharyngolaryngeal pain, sinusitis, influenza, back pain, nasal congestion, stomach discomfort, vomiting, and oral candidiasis. ( 6.1 )
• COPD: nasopharyngitis, oral candidiasis, bronchitis, sinusitis, upper respiratory tract infections.

In these trials, the patients on budesonide and formoterol fumarate dihydrate inhalation aerosol had a mean age of 38 years and were predominantly Caucasian (82%). The incidence of common adverse events in Table 2 below is based upon pooled data from three 12‑week, double-blind, placebo-controlled clinical studies in which 401 adult and adolescent patients (148 males and 253 females) age 12 years and older were treated with 2 inhalations of budesonide and formoterol fumarate dihydrate inhalation aerosol 80 mcg/4.5 mcg or budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg twice daily. The budesonide and formoterol fumarate dihydrate inhalation aerosol group was composed of mostly Caucasian (84%) patients with a mean age of 38 years, and a mean percent predicted FEV 1 at baseline of 76 and 68 for the 80 mcg/4.5 mcg and 160 mcg/4.5 mcg treatment groups, respectively. Control arms for comparison included 2 inhalations of budesonide HFA metered dose inhaler (MDI) 80 mcg or 160 mcg, formoterol dry powder inhaler (DPI) 4.5 mcg, or placebo (MDI and DPI) twice daily. Table 2 includes all adverse events that occurred at an incidence of ≥ 3% in any one budesonide and formoterol fumarate dihydrate inhalation aerosol group and more commonly than in the placebo group with twice-daily dosing. In considering these data, the increased average duration of patient exposure for budesonide and formoterol fumarate dihydrate inhalation aerosol patients should be taken into account, as incidences are not adjusted for an imbalance of treatment duration.

Similarly, no significant or unexpected patterns of abnormalities were observed for up to 1 year in safety measures including chemistry, hematology, ECG, Holter monitor, and HPA-axis assessments. Pediatric Patients 6 to Less Than 12 Years of Age The safety data for pediatric patients aged 6 to less than 12 years is based on 1 trial of 12 weeks treatment duration. Patients (79 female and 105 male) receiving inhaled corticosteroid at trial entry were randomized to budesonide and formoterol fumarate dihydrate inhalation aerosol 80 mcg/4.5 mcg (n = 92) or budesonide pMDI 80 mcg (n = 92), 2 inhalations twice daily. The overall safety profile of these patients was similar to that observed in patients 12 years of age and older who received budesonide and formoterol fumarate dihydrate inhalation aerosol 80 mcg/4.5 mcg twice daily in studies of similar design. Common adverse reactions that occurred in patients treated with budesonide and formoterol fumarate dihydrate inhalation aerosol 80 mcg/4.5 mcg with a frequency of ≥ 3% and more frequently than patients treated only with budesonide pMDI 80 mcg included upper respiratory tract infection, pharyngitis, headache, and rhinitis. 6.2 Clinical Trials Experience in Chronic Obstructive Pulmonary Disease The safety data described below reflect exposure to budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg in 1783 patients. Budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg was studied in two placebo-controlled lung function studies (6 and 12 months in duration), and two active-controlled exacerbation studies (6 and 12 months in duration) in patients with COPD. The incidence of common adverse events in Table 3 below is based upon pooled data from two double-blind, placebo-controlled lung function clinical studies (6 and 12 months in duration) in which 771 adult COPD patients (496 males and 275 females) 40 years of age and older were treated with budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg, two inhalations twice daily. Of these patients 651 were treated for 6 months and 366 were treated for 12 months. The budesonide and formoterol fumarate dihydrate inhalation aerosol group was composed of mostly Caucasian (93%) patients with a mean age of 63 years, and a mean percent predicted FEV 1 at baseline of 33%. Control arms for comparison included 2 inhalations of budesonide HFA (MDI) 160 mcg, formoterol (DPI) 4.5 mcg or placebo (MDI and DPI) twice daily. Table 3 includes all adverse events that occurred at an incidence of ≥ 3% in the budesonide and formoterol fumarate dihydrate inhalation aerosol group and more commonly than in the placebo group. In considering these data, the increased average duration of patient exposure to budesonide and formoterol fumarate dihydrate inhalation aerosol should be taken into account, as incidences are not adjusted for an imbalance of treatment duration. Table 3. Adverse Reactions Occurring at an Incidence of ≥ 3% and More Commonly Than Placebo in the Budesonide and Formoterol Fumarate Dihydrate Inhalation Aerosol Group: Pooled Data From Two Double-blind, Placebo-controlled Clinical COPD Trials Treatment All treatments were administered as 2 inhalations twice daily. Budesonide and Formoterol Fumarate Dihydrate Inhalation Aerosol Budesonide Formoterol Placebo Adverse Event 160 mcg/4.5 mcg N = 771 % 160 mcg N = 275 % 4.5 mcg N = 779 % N = 781 % Nasopharyngitis 7.3 3.3 5.8 4.9 Oral candidiasis 6.0 4.4 1.2 1.8 Bronchitis 5.4 4.7 4.5 3.5 Sinusitis 3.5 1.5 3.1 1.8 Upper respiratory tract infection viral 3.5 1.8 3.6 2.7 Average Duration of Exposure (days) 255.2 157.1 240.3 223.7 Lung infections other than pneumonia (mostly bronchitis) occurred in a greater percentage of subjects treated with budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg compared with placebo (7.9% vs. 5.1%, respectively). There were no clinically important or unexpected patterns of abnormalities observed for up to 1 year in chemistry, hematology, ECG, ECG (Holter) monitoring, HPA-axis, bone mineral density and ophthalmology assessments. The safety findings from the two double-blind, active-controlled exacerbations studies (6 and 12 months in duration) in which 1012 adult COPD patients (616 males and 396 females) 40 years of age and older were treated with budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg, two inhalations twice daily were consistent with the lung function studies. 6.3 Postmarketing Experience The following adverse reactions have been identified during post-approval use of budesonide and formoterol fumarate dihydrate inhalation aerosol. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Some of these adverse reactions may also have been observed in clinical studies with budesonide and formoterol fumarate dihydrate inhalation aerosol. Cardiac Disorders: angina pectoris, tachycardia, atrial and ventricular tachyarrhythmias, atrial fibrillation, extrasystoles, palpitations Endocrine Disorders: hypercorticism, growth velocity reduction in pediatric patients Eye Disorders: cataract, glaucoma, increased intraocular pressure Gastrointestinal Disorders: oropharyngeal candidiasis, nausea Immune System Disorders: immediate and delayed hypersensitivity reactions, such as anaphylactic reaction, angioedema, bronchospasm, urticaria, exanthema, dermatitis, pruritus Metabolic and Nutrition Disorders: hyperglycemia, hypokalemia Musculoskeletal, Connective Tissue, and Bone Disorders: muscle cramps Nervous System Disorders: tremor, dizziness Psychiatric Disorders: behavior disturbances, sleep disturbances, nervousness, agitation, depression, restlessness Respiratory, Thoracic, and Mediastinal Disorders: dysphonia, cough, throat irritation Skin and Subcutaneous Tissue Disorders: skin bruising Vascular Disorders: hypotension, hypertension

• In clinical studies, concurrent administration of budesonide and formoterol fumarate dihydrate inhalation aerosol and other drugs, such as short-acting beta 2 -agonists, intranasal corticosteroids, and antihistamines/decongestants has not resulted in an increased frequency of adverse reactions. No formal drug interaction studies have been performed with budesonide and formoterol fumarate dihydrate inhalation aerosol.
• Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir): Use with caution. May cause increased systemic corticosteroid effects. ( 7.1 )
• Monoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution. May potentiate effect of formoterol on vascular system. ( 7.2 )
• Beta-blockers: Use with caution. May block bronchodilatory effects of beta-agonists and produce severe bronchospasm. ( 7.3 )
• Diuretics: Use with caution. Electrocardiographic changes and/or hypokalemia associated with non-potassium-sparing diuretics may worsen with concomitant beta-agonists. ( 7.4 ) 7.1 Inhibitors of Cytochrome P4503A4 The main route of metabolism of corticosteroids, including budesonide, a component of BREYNA, is via cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4). After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally administered budesonide increased. Concomitant administration of CYP3A4 may inhibit the metabolism of, and increase the systemic exposure to, budesonide. Caution should be exercised when considering the coadministration of BREYNA with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.9) ] . 7.2 Monoamine Oxidase Inhibitors and Tricyclic Antidepressants BREYNA should be administered with caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of formoterol, a component of BREYNA, on the vascular system may be potentiated by these agents. In clinical trials with budesonide and formoterol fumarate dihydrate inhalation aerosol, a limited number of COPD and asthma patients received tricyclic antidepressants, and, therefore, no clinically meaningful conclusions on adverse events can be made. 7.3 Beta-Adrenergic Receptor Blocking Agents Beta-blockers (including eye drops) may not only block the pulmonary effect of beta-agonists, such as formoterol, a component of BREYNA, 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, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents in patients with asthma. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution. 7.4 Diuretics 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 BREYNA with non-potassium-sparing diuretics.

Pregnancy Risk Summary There are no adequate and well-controlled studies of budesonide and formoterol fumarate dihydrate inhalation aerosol or one of its individual components, formoterol fumarate, in pregnant women; however studies are available for the other component budesonide. In animal reproduction studies, budesonide and formoterol fumarate dihydrate, administered by the inhalation route, was teratogenic, embryocidal, and reduced fetal weights in rats at less than the maximum recommended human daily inhalation dose (MRHDID) on a mcg/m 2 basis. Budesonide alone, administered by the subcutaneous route, was teratogenic, embryocidal, and reduced fetal weights in rats and rabbits at less than the MRHDID, but these effects were not seen in rats that received inhaled doses up to 4 times the MRHDID. Studies of pregnant women have not shown that inhaled budesonide alone increases the risk of abnormalities when administered during pregnancy.

Experience with oral corticosteroids suggests that rodents are more prone to teratogenic effects from corticosteroid exposure than humans. Formoterol fumarate alone, administered by the oral route, was teratogenic in rats and rabbits at 1600 and 65,000 times the MRHDID, respectively. Formoterol fumarate was also embryocidal, increased pup loss at birth and during lactation, and decreased pup weight in rats at 110 times the MRHDID. These adverse effects generally occurred at large multiples of the MRHDID when formoterol fumarate was administered by the oral route to achieve high systemic exposures.

No teratogenic, embryocidal, or developmental effects were seen in rats that received inhalation doses up to 375 times the MRHDID. The estimated background risk of major birth defects and miscarriage of the indicated populations is unknown. In the U.S. general population, the estimated background 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 well-controlled human studies that have investigated the effects of budesonide and formoterol fumarate dihydrate inhalation aerosol during labor and delivery. Because of the potential for beta-agonist interference with uterine contractility, use of BREYNA during labor should be restricted to those patients in whom the benefits clearly outweigh the risk.

Data Human Data Studies of pregnant women have not shown that inhaled budesonide increases the risk of abnormalities when administered during pregnancy. The results from a large population-based prospective cohort epidemiological study reviewing data from three Swedish registries covering approximately 99% of the pregnancies from 1995-1997 (i.e., Swedish Medical Birth Registry; Registry of Congenital Malformations; Child Cardiology Registry) indicate no increased risk for congenital malformations from the use of inhaled budesonide during early pregnancy. Congenital malformations were studied in 2014 infants born to mothers reporting the use of inhaled budesonide for asthma in early pregnancy (usually 10-12 weeks after the last menstrual period), the period when most major organ malformations occur.

The rate of recorded congenital malformations was similar compared to the general population rate (3.8% vs. 3.5%, respectively). In addition, after exposure to inhaled budesonide, the number of infants born with orofacial clefts was similar to the expected number in the normal population (4 children vs. 3.3, respectively). These same data were utilized in a second study bringing the total to 2534 infants whose mothers were exposed to inhaled budesonide. In this study, the rate of congenital malformations among infants whose mothers were exposed to inhaled budesonide during early pregnancy was not different from the rate for all newborn babies during the same period (3.6%). Animal Data Budesonide and Formoterol Fumarate Dihydrate Inhalation Aerosol In an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6-16, budesonide and formoterol fumarate dihydrate inhalation aerosol produced umbilical hernia in fetuses at doses less than the MRHDID (on a mcg/m 2 basis at maternal inhaled doses of 12/0.66 mcg/kg/day and above). Fetal weights were reduced at approximately 5 and 3 times the MRHDID, respectively (on an AUC basis at a maternal inhaled dose of 80/4.4 mcg/kg (budesonide/formoterol)). No teratogenic or embryocidal effects were detected at doses less than the MRHDID (on a mcg/m 2 basis at a maternal inhaled dose of 2.5/0.14 mcg/kg/day). Budesonide In a fertility and reproduction study, male rats were subcutaneously dosed for 9 weeks and females for 2 weeks prior to pairing and throughout the mating period. Females were dosed up until weaning of their offspring.

Budesonide caused a decrease in prenatal viability and viability in the pups at birth and during lactation, along with a decrease in maternal body-weight gain, at doses less than the MRHDID (on a mcg/m 2 basis at maternal subcutaneous doses of 20 mcg/kg/day and above). No such effects were noted at a dose less than the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 5 mcg/kg/day). In an embryo-fetal development study in pregnant rabbits dosed during the period of organogenesis from gestation days 6-18, budesonide produced fetal loss, decreased fetal weight, and skeletal abnormalities at doses less than the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 25 mcg/kg/day). In an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6-15, budesonide produced similar adverse fetal effects at doses approximately 8 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 500 mcg/kg/day). In another embryo- fetal development study in pregnant rats, no teratogenic or embryocidal effects were seen at doses up to 4 times the MRHDID (on a mcg/m 2 basis at maternal inhalation doses up to 250 mcg/kg/day). In a peri-and post-natal development study, rats dosed from gestation day 15 to postpartum day 21, budesonide had no effects on delivery, but did have an effect on growth and development of offspring. Offspring survival was reduced and surviving offspring had decreased mean body weights at birth and during lactation at doses less than the MRHDID and higher (on a mcg/m 2 basis at maternal subcutaneous doses of 20 mcg/kg/day and higher). These findings occurred in the presence of maternal toxicity. Formoterol In a fertility and reproduction study, male rats were orally dosed for 9 weeks and females for 2 weeks prior to pairing and throughout the mating period.

Females were either dosed up to gestation day 19 or up until weaning of their offspring. Males were dosed up to 25 weeks. Umbilical hernia was observed in rat fetuses at oral doses 1600 times and greater than the MRHDID (on a mcg/m 2 basis at maternal oral doses of 3000 mcg/kg/day and higher). Brachygnathia was observed in rat fetuses at a dose 8000 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 15,000 mcg/kg/day). Pregnancy was prolonged at a dose 8000 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 15,000 mcg/kg/day). Fetal and pup deaths occurred at doses approximately 1600 times the MRHDID and higher (on a mcg/m 2 basis at oral doses of 3000 mcg/kg/day and higher) during gestation.

In an embryo-fetal development study in pregnant rats dosed during the period of organogenesis from gestation days 6-15, no teratogenic, embryocidal or developmental effects were seen at doses up to 375 times the MRHDID (on a mcg/m 2 basis with maternal inhalation doses up to 690 mcg/kg/day). In an embryo-fetal development study in pregnant rabbits dosed during the period of organogenesis from gestation days 6-18, subcapsular cysts on the liver were observed in the fetuses at a dose 65,000 times the MRHDID (on a mcg/m 2 basis with a maternal oral dose of 60,000 mcg/kg/day). No teratogenic effects were observed at doses up to 3800 times the MRHDID (on a mcg/m 2 basis at maternal oral doses up to 3500 mcg/kg/day). In a pre- and post-natal development study, pregnant female rats received formoterol at oral doses of 0, 210, 840, and 3400 mcg/kg/day from gestation day 6 through the lactation period. Pup survival was decreased from birth to postpartum day 26 at doses 110 times the MRHDID and higher (on a mcg/m 2 basis at maternal oral doses of 210 mcg/kg/day and higher), although there was no evidence of a dose-response relationship. There were no treatment-related effects on the physical, functional, and behavioral development of rat pups.

Pediatric Use Safety and effectiveness of budesonide and formoterol fumarate dihydrate inhalation aerosol in asthma patients 12 years of age and older have been established in studies up to 12 months. In the two 12-week, double-blind, placebo-controlled US pivotal studies 25 patients 12 to 17 years of age were treated with budesonide and formoterol fumarate dihydrate inhalation aerosol twice daily . Efficacy results in this age group were similar to those observed in patients 18 years and older. There were no obvious differences in the type or frequency of adverse events reported in this age group compared with patients 18 years of age and older.

The safety and effectiveness of budesonide and formoterol fumarate dihydrate inhalation aerosol 80 mcg/4.5 mcg in asthma patients 6 to less than 12 years of age have been established in studies of up to 12-week duration . The safety profile in these patients was consistent to that observed in patients 12 years of age and older who also received budesonide and formoterol fumarate dihydrate inhalation aerosol . The safety and effectiveness of budesonide and formoterol fumarate dihydrate inhalation aerosol in asthma patients less than 6 years of age have not been established. Controlled clinical studies have shown that orally inhaled corticosteroids including budesonide, a component of BREYNA, may cause a reduction in growth velocity in pediatric patients. This effect has been observed in the absence of laboratory evidence of HPA-axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA-axis function.

The long-term effect of this reduction in growth velocity associated with orally inhaled corticosteroids, including the impact on final height are unknown. The potential for “catch-up” growth following discontinuation of treatment with orally inhaled corticosteroids has not been adequately studied. In a study of asthmatic children 5 to 12 years of age, those treated with budesonide DPI 200 mcg twice daily (n = 311) had a 1.1 centimeter reduction in growth compared with those receiving placebo (n = 418) at the end of one year; the difference between these two treatment groups did not increase further over three years of additional treatment.

By the end of 4 years, children treated with budesonide DPI and children treated with placebo had similar growth velocities. Conclusions drawn from this study may be confounded by the unequal use of corticosteroids in the treatment groups and inclusion of data from patients attaining puberty during the course of the study. The growth of pediatric patients receiving orally inhaled corticosteroids, including BREYNA, should be monitored.

If a child or adolescent on any corticosteroid appears to have growth suppression, the possibility that he/she is particularly sensitive to this effect should be considered. The potential growth effects of prolonged treatment should be weighed against the clinical benefits obtained. To minimize the systemic effects of orally inhaled corticosteroids, including BREYNA, each patient should be titrated to the lowest strength that effectively controls his/her asthma .

• The use of BREYNA is contraindicated in the following conditions:
• Primary treatment of status asthmaticus or other acute episodes of asthma or COPD where intensive measures are required.
• Hypersensitivity to any of the ingredients in BREYNA.
• Primary treatment of status asthmaticus or acute episodes of asthma or COPD requiring intensive measures ( 4 )
• Hypersensitivity to any of the ingredients in BREYNA ( 4 )

contains both budesonide and formoterol fumarate dihydrate; therefore, the risks associated with overdosage for the individual components described below apply to BREYNA. In pharmacokinetic studies, single doses of 960/54 mcg (12 actuations of budesonide and formoterol fumarate dihydrate inhalation aerosol 80 mcg/4.5 mcg) and 1280/36 mcg (8 actuations of 160 mcg/4.5 mcg), were administered to patients with COPD. A total of 1920/54 mcg (12 actuations of budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg) was administered as a single dose to both healthy subjects and patients with asthma. In a long-term active-controlled safety study in adolescent and adult asthma patients 12 years of age and older, budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg was administered for up to 12 months at doses up to twice the highest recommended daily dose. There were no clinically significant adverse reactions observed in any of these studies.

Budesonide The potential for acute toxic effects following overdose of budesonide is low. If used at excessive doses for prolonged periods, systemic corticosteroid effects such as hypercorticism may occur . Budesonide at five times the highest recommended dose (3200 mcg daily) administered to humans for 6 weeks caused a significant reduction (27%) in the plasma cortisol response to a 6-hour infusion of ACTH compared with placebo (+1%). The corresponding effect of 10 mg prednisone daily was a 35% reduction in the plasma cortisol response to ACTH. Formoterol An overdose of formoterol would likely lead to an exaggeration of effects that are typical for beta 2 ‑agonists: seizures, angina, hypertension, hypotension, tachycardia, atrial and ventricular tachyarrhythmias, nervousness, headache, tremor, palpitations, muscle cramps, nausea, dizziness, sleep disturbances, metabolic acidosis, hyperglycemia, hypokalemia. As with all sympathomimetic medications, cardiac arrest and even death may be associated with abuse of formoterol.

No clinically significant adverse reactions were seen when formoterol was delivered to adult patients with acute bronchoconstriction at a dose of 90 mcg/day over 3 hours or to stable asthmatics 3 times a day at a total dose of 54 mcg/day for 3 days. Treatment of formoterol overdosage consists of discontinuation of the medication together with institution of appropriate symptomatic and/or supportive therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm.

There is insufficient evidence to determine if dialysis is beneficial for overdosage of formoterol. Cardiac monitoring is recommended in cases of overdosage.
