What it is used for
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.
Maintenance treatment of airflow obstruction and reducing exacerbations in patients with chronic obstructive pulmonary disease (COPD) including chronic bronchitis and/or emphysema. Important limitations:
Not indicated for the relief of acute bronchospasm.
1.1 Treatment 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.
1.2 Maintenance
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.

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. 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. Budesonide is provided as a mixture of two epimers (22R and 22S). The empirical formula of budesonide is C 25 H 34 O 6 and its molecular weight is 430.5.
Its structural formula is: Budesonide is a white to off-white, tasteless, odorless powder which is practically insoluble in water and in heptane, sparingly soluble in ethanol, and freely soluble in chloroform. Its partition coefficient between octanol and water at pH 7.4 is 1.6 x 10 3. The other active component of BREYNA is formoterol fumarate dihydrate, a selective beta 2 -agonist designated chemically as (R*,R*)-(±)-N-[2-hydroxy-5-[1-hydroxy-2-[[2-(4-methoxyphenyl)-1-methylethyl]amino]ethyl]phenyl]formamide, (E)-2-butendioate(2:1), dihydrate. The empirical formula of formoterol is C 42 H 56 N 4 O 14 and its molecular weight is 840.9.
Its structural formula is: Formoterol fumarate dihydrate is a powder which is slightly soluble in water. Its octanol-water partition coefficient at pH 7.4 is 2.6. The pKa of formoterol fumarate dihydrate at 25°C is 7.9 for the phenolic group and 9.2 for the amino group. Budesonide Structural Formula Formoterol Fumarate Dihydrate Structrual Formula
