🩺 Clinical
Budesonide and formoterol is used to prevent and treat difficulty breathing, wheezing, shortness of breath, coughing, and chest tightness caused by asthma and to treat chronic obstructive pulmonary (COPD; a group of diseases that affect the lungs and airways, that includes chronic bronchitis and emphysema) in adults. Budesonide is in a class of medications called steroids. It works by reducing swelling in the airways. Formoterol is in a class of medications called long-acting beta agonists (LABAs). It works by relaxing and opening air passages in the lungs, making it easier to breathe.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE BREYNA is a combination product containing a corticosteroid and a long-acting beta 2 -adrenergic agonist indicated for: • Treatment of asthma in patients 6 years of age and older. ( 1.1 ) • Maintenance treatment of airflow obstruction and reducing exacerbations in patients with chronic obstructive pulmonary disease (COPD) including chronic bronchitis and/or emphysema. ( 1.2 ) Important limitations: • Not indicated for the relief of acute bronchospasm.
( 1.1 , 1.2 )
1.1Treatment of Asthma BREYNA is indicated for the treatment of asthma in patients 6 years of age and older. BREYNA should be used for patients not adequately controlled on a long-term asthma-control medication such as an inhaled corticosteroid (ICS) or whose disease warrants initiation of treatment with both an inhaled corticosteroid and long-acting beta 2 -adrenergic agonist (LABA). Important Limitations of Use: • BREYNA is NOT indicated for the relief of acute bronchospasm.
1.2Maintenance Treatment of Chronic Obstructive Pulmonary Disease BREYNA 160 mcg/4.5 mcg is indicated for the maintenance treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD) including chronic bronchitis and/or emphysema. BREYNA 160 mcg/4.5 mcg is also indicated to reduce exacerbations of COPD. BREYNA 160 mcg/4.5 mcg is the only strength indicated for the treatment of COPD.
Important Limitations of Use: • BREYNA is NOT indicated for the relief of acute bronchospasm.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION 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 )
2.1Administration 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) ] .
2.2Asthma 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.
2.3Chronic 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.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Serious asthma-related events: Long-acting beta 2 -adrenergic agonists as monotherapy increase the risk. ( 5.1 ) • Deterioration of disease and acute episodes: Do not initiate in acutely deteriorating asthma or COPD or to treat acute symptoms. ( 5.2 ) • Use with additional long-acting beta 2 -agonist: Do not use in combination because of risk of overdose.
( 5.3 ) • Localized infections: Candida albicans infection of the mouth and throat may occur. Monitor patients periodically for signs of adverse effects on the oral cavity. Advise the patient to rinse his/her mouth with water without swallowing after inhalation to help reduce the risk.
( 5.4 ) • Pneumonia: Increased risk in patients with COPD. Monitor patients for signs and symptoms of pneumonia and other potential lung infections. ( 5.5 ) • Immunosuppression: Potential worsening of infections (e.g., existing tuberculosis, fungal, bacterial, viral, or parasitic infection; or ocular herpes simplex).
Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients. ( 5.6 ) • Transferring patients from systemic corticosteroids: Risk of impaired adrenal function when transferring from oral steroids.
Taper patients slowly from systemic corticosteroids if transferring to BREYNA. ( 5.7 ) • Hypercorticism and adrenal suppression: May occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, discontinue BREYNA slowly.
( 5.8 ) • Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir): Risk of increased systemic corticosteroid effects. Exercise caution when used with BREYNA. ( 5.9 ) • Paradoxical bronchospasm: Discontinue BREYNA and institute alternative therapy if paradoxical bronchospasm occurs.
( 5.10 ) • Patients with cardiovascular or central nervous system disorders: Use with caution because of beta-adrenergic stimulation. ( 5.12 ) • Decreases in bone mineral density: Assess bone mineral density initially and periodically thereafter. ( 5.13 ) • Effects on growth: Monitor growth of pediatric patients.
( 5.14 ) • Glaucoma and cataracts: Close monitoring is warranted. ( 5.15 ) • Metabolic effects: Be alert to eosinophilic conditions, hypokalemia, and hyperglycemia. ( 5.16 , 5.18 ) • Coexisting conditions: Use with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, and ketoacidosis.

5.1Serious Asthma-Related Events – Hospitalizations, Intubations and Death Use of LABA as monotherapy (without ICS) for asthma is associated with an increased risk of asthma-related death [see Salmeterol Multicenter Asthma Research Trial (SMART) ]. Available data from controlled clinical trials also suggest that use of LABA as monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patients. These findings are considered a class effect of LABA.
When LABA are used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared to ICS alone (see Serious Asthma-Related Events with ICS/LABA ). Serious Asthma-Related Events with ICS/LABA Four large, 26-week, randomized, blinded, active-controlled clinical safety trials were conducted to evaluate the risk of serious asthma-related events when LABA were used in fixed-dose combination with ICS compared to ICS alone in patients with asthma.
Three trials included adult and adolescent patients aged ≥ 12 years: one trial compared budesonide/formoterol (budesonide and formoterol fumarate dihydrate inhalation aerosol) to budesonide [see Clinical Studies (14.1) ] ; one trial compared fluticasone propionate/salmeterol inhalation powder to fluticasone propionate inhalation powder; and one trial compared mometasone furoate/formoterol to mometasone furoate. The fourth trial included pediatric patients 4 to 11 years…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS LABA use may result in the following: • Serious asthma-related events – hospitalizations, intubations, death [see Warnings and Precautions (5.1) ] . • Cardiovascular and central nervous system effects [see Warnings and Precautions (5.12) ] . Systemic and inhaled corticosteroid use may result in the following: • Candida albicans infection [see Warnings and Precautions (5.4) ] • Pneumonia or lower respiratory tract infections in patients with COPD [see Warnings and Precautions (5.5) ] • Immunosuppression [see Warnings and Precautions (5.6) ] • Hypercorticism and adrenal suppression [see Warnings and Precautions (5.8) ] • Growth effects in pediatric patients [see Warnings and Precautions (5.14) ] • 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.

6.1Clinical Trials Experience in Asthma Adult and Adolescent Patients 12 Years of Age and Older The overall safety data in adults and adolescents are based upon 10 active- and placebo-controlled clinical trials in which 3393 patients ages 12 years and older (2052 females and 1341 males) with asthma of varying severity were treated with budesonide and formoterol fumarate dihydrate inhalation aerosol 80 mcg/4.5 mcg or 160 mcg/4.5 mcg taken 2 inhalations once or twice daily for 12 to 52 weeks. 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.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS 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 )
7.1Inhibitors 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) ] .
7.2Monoamine 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.
7.3Beta-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.
7.4Diuretics 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.

8.1Pregnancy 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…

🧒 Pediatric Use ▾
8.4Pediatric 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 [see Clinical Studies (14.1) ] . 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 [see Clinical Studies (14.1) ] . 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 [see Adverse Reactions (6.1) ] .
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 [see Dosage and Administration (2) ] .
🧓 Geriatric Use ▾
8.5Geriatric Use Of the total number of asthma patients treated with budesonide and formoterol fumarate dihydrate inhalation aerosol twice daily in two 12-week studies and a 26-week postmarketing study, 791 were 65 years of age or older, of whom 141 were 75 years of age or older. In the COPD studies of 6 to 12 months duration, 810 patients treated with budesonide and formoterol fumarate dihydrate inhalation aerosol 160 mcg/4.5 mcg, two inhalations twice daily were 65 years old and above and of those, 177 patients were 75 years of age and older.
No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. As with other products containing beta 2 -agonists, special caution should be observed when using BREYNA in geriatric patients who have concomitant cardiovascular disease that could be adversely affected by beta 2 -agonists. Based on available data for budesonide and formoterol fumarate dihydrate inhalation aerosol or its active components, no adjustment of dosage of BREYNA in geriatric patients is warranted.
🆘 Overdosage ▾
10 OVERDOSAGE BREYNA BREYNA 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 [see Warnings and Precautions (5) ] . 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.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action BREYNA BREYNA contains both budesonide and formoterol fumarate dihydrate; therefore, the mechanisms of action described below for the individual components apply to BREYNA. These drugs represent two classes of medications (a synthetic corticosteroid and a long-acting selective beta 2 -adrenoceptor agonist) that have different effects on clinical, physiological, and inflammatory indices of COPD and asthma. Budesonide Budesonide is an anti-inflammatory corticosteroid that exhibits potent glucocorticoid activity and weak mineralocorticoid activity.
In standard in vitro and animal models, budesonide has approximately a 200-fold higher affinity for the glucocorticoid receptor and a 1000-fold higher topical anti-inflammatory potency than cortisol (rat croton oil ear edema assay). As a measure of systemic activity, budesonide is 40 times more potent than cortisol when administered subcutaneously and 25 times more potent when administered orally in the rat thymus involution assay. In glucocorticoid receptor affinity studies, the 22R form of budesonide was two times as active as the 22S epimer.
In vitro studies indicated that the two forms of budesonide do not interconvert. Inflammation is an important component in the pathogenesis of COPD and asthma. Corticosteroids have a wide range of inhibitory activities against multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in allergic and non–allergic-mediated inflammation.
These anti-inflammatory actions of corticosteroids may contribute to their efficacy in COPD and asthma. Studies in asthmatic patients have shown a favorable ratio between topical anti-inflammatory activity and systemic corticosteroid effects over a wide range of doses of budesonide. This is explained by a combination of a relatively high local anti-inflammatory effect, extensive first pass hepatic degradation of orally absorbed drug (85%-95%), and the low potency of formed metabolites.
Formoterol Formoterol fumarate dihydrate is a long-acting selective beta 2 -adrenergic agonist (beta 2 -agonist) with a rapid onset of action. Inhaled formoterol fumarate dihydrate acts locally in the lung as a bronchodilator. In vitro studies have shown that formoterol has more than 200-fold greater agonist activity at beta 2 -receptors than at beta 1 -receptors.
The in vitro binding selectivity to beta 2 - over beta 1 -adrenoceptors is higher for formoterol than for albuterol (5 times), whereas salmeterol has a higher (3 times) beta 2 -selectivity ratio than formoterol. Although beta 2 -receptors are the predominant adrenergic receptors in bronchial smooth muscle and beta 1 -receptors are the predominant receptors in the heart, there are also beta 2 -receptors in the human heart comprising 10% to 50% of the total beta-adrenergic receptors. The precise function of these receptors has not been established, but they raise the possibility that even highly selective beta 2 -agonists may have cardiac effects.
The pharmacologic effects of beta 2 -adrenoceptor agonist drugs, including formoterol, are at least in part attributable to stimulation of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3', 5’-adenosine monophosphate (cyclic AMP). Increased cyclic AMP levels cause relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells. In vitro tests show that formoterol is an inhibitor of the release of mast cell mediators, such as histamine and leukotrienes, from the human lung.
Formoterol also inhibits histamine-induced plasma albumin extravasation in anesthetized guinea pigs and inhibits allergen-induced eosinophil influx in dogs with airway hyper-responsiveness. The relevance of these in vitro and animal findings to humans…

📋 Description ▾
11 DESCRIPTION BREYNA 80 mcg/4.5 mcg and BREYNA 160 mcg/4.5 mcg each contain micronized budesonide and micronized formoterol fumarate dihydrate for oral inhalation only. Each BREYNA 80 mcg/4.5 mcg and BREYNA 160 mcg/4.5 mcg canister is formulated as a hydrofluoroalkane (HFA 227; 1,1,1,2,3,3,3-heptafluoropropane)-propelled pressurized metered dose inhaler containing 120 actuations [see Dosage Forms and Strengths (3) and How Supplied/Storage and Handling (16) ] . After priming, each actuation meters either 91/5.1 mcg or 181/5.1 mcg from the valve and delivers either 80/4.5 mcg, or 160/4.5 mcg (budesonide micronized/formoterol fumarate dihydrate micronized) 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. BREYNA also contains povidone K25 USP as a suspending agent and polyethylene glycol 1000 NF as a lubricant. BREYNA should be primed 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 for 5 seconds before each spray and releasing two test sprays into the air away from the face. One active component of BREYNA is budesonide, a corticosteroid designated chemically as (RS)‑11β, 16α, 17,21-Tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17-acetal with butyraldehyde.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Patient Information and Instructions for Use ). Serious Asthma-Related Events: Inform patients with asthma that LABA when used alone increases the risk of asthma-related hospitalization or asthma-related death. Available data show that when ICS and LABA are used together, such as with BREYNA, there is not a significant increase in risk of these events.
Not for Acute Symptoms: Inform patients that BREYNA is not meant to relieve acute symptoms of asthma or COPD and extra doses should not be used for that purpose. Advise patients to treat acute symptoms with an inhaled, short-acting beta 2 -agonist such as albuterol. Provide patients with such medication and instruct the patient in how it should be used.
Instruct patients to seek medical attention immediately if they experience any of the following: • Decreasing effectiveness of inhaled, short-acting beta 2 -agonists • Need for more inhalations than usual of inhaled, short-acting beta 2 -agonists • Significant decrease in lung function as outlined by the physician Tell patients they should not stop therapy with BREYNA without physician/provider guidance since symptoms may recur after discontinuation. Do Not Use Additional Long-Acting Beta 2 -Agonists: Instruct patients not to use other LABA for asthma and COPD.
Local Effects: Inform patients that localized infections with Candida albicans occurred in the mouth and pharynx in some patients. If oropharyngeal candidiasis develops, it should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while still continuing therapy with BREYNA, but at times therapy with BREYNA may need to be temporarily interrupted under close medical supervision. Rinsing the mouth with water without swallowing after inhalation is advised to reduce the risk of thrush.
Pneumonia: Patients with COPD have a higher risk of pneumonia; instruct them to contact their healthcare provider if they develop symptoms of pneumonia. Immunosuppression: Warn patients who are on immunosuppressant doses of corticosteroids to avoid exposure to chicken pox or measles and, if exposed, to consult their physician without delay. Inform patients of potential worsening of existing tuberculosis, fungal, bacterial, viral, or parasitic infections, or ocular herpes simplex.
Hypercorticism and Adrenal Suppression: Advise patients that BREYNA may cause systemic corticosteroid effects of hypercorticism and adrenal suppression. Additionally, inform patients that deaths due to adrenal insufficiency have occurred during and after transfer from systemic corticosteroids. Patients should taper slowly from systemic corticosteroids if transferring to BREYNA.
Reduction in Bone Mineral Density: Advise patients who are at an increased risk for decreased BMD that the use of corticosteroids may pose an additional risk. Reduced Growth Velocity: Inform patients that orally inhaled corticosteroids, a component of BREYNA, may cause a reduction in growth velocity when administered to pediatric patients. Physicians should closely follow the growth of children and adolescents taking corticosteroids by any route.
Ocular Effects: Long-term use of inhaled corticosteroids may increase the risk of some eye problems (cataracts or glaucoma); consider regular eye examinations. Risks Associated with Beta-Agonist Therapy: Inform patients of adverse effects associated with beta 2 -agonists, such as palpitations, chest pain, rapid heart rate, tremor, or nervousness.
