Budesonide and Formoterol Fumarate Mechanism, CYP450 Pathways & DailyMed Monograph

RxCUI 1246288 • NDC 0378-7502

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 ) 1.1 Treatment of Asthma BREYNA is indicated for the treatment of asthma in patients 6 years of age and older.

12.1 Mechanism 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.

Pharmacokinetic profiling of Budesonide and Formoterol Fumarate demonstrates an elimination half-life of Approximately 3–10 hours terminal plasma half-life for Budesonide and Formoterol Fumarate with Estimated 51%–63% oral systemic absorption for Budesonide and Formoterol Fumarate systemic bioavailability; clearance proceeds via phase i/ii hepatic conjugation of budesonide and formoterol fumarate coupled with glomerular and tubular renal excretion, reaching clinical onset within peak plasma tmax within 1 to 2 hours (budesonide and formoterol fumarate).

Titration schedules for Budesonide and Formoterol Fumarate (160 ug/1 / 4.5 ug/1 Aerosol, Metered → 80 ug/1 / 4.5 ug/1 Aerosol, Metered) require excluding 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.; real-world patient logs highlight nausea (9.3% of reports), headache (7.5% of reports), fatigue (5.5% of reports) alongside a 80.00% Worth-It consensus.

Key Monitored Interactions:
Potent CYP3A4 Inhibitors (Azoles, Clarithromycin, Ritonavir) Major

Strong CYP3A4 blockade slows first-pass metabolism of Budesonide and Formoterol Fumarate, elevating systemic AUC exposure.

Duplicate Corticosteroid Agents Moderate

Avoid overlapping corticosteroid prescriptions alongside Budesonide and Formoterol Fumarate to prevent cumulative receptor toxicity.

Approximately 3–10 hours terminal plasma half-life for Budesonide and Formoterol Fumarate
Bioavailability
Estimated 51%–63% oral systemic absorption for Budesonide and Formoterol Fumarate
Metabolism & Clearance
Phase I/II hepatic conjugation of Budesonide and Formoterol Fumarate coupled with glomerular and tubular renal excretion
