Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Combination of fluticasone furoate, a corticosteroid that binds to glucocorticoid receptors to inhibit inflammatory gene transcription, and vilanterol, a long-acting beta2-adrenergic agonist that activates adenylate cyclase leading to bronchodilation.
Beta-2 adrenergic receptor agonist; stimulates adenylate cyclase, increasing c AMP, leading to bronchodilation and inhibition of mast cell mediator release.
Maintenance treatment of chronic obstructive pulmonary disease (COPD) including chronic bronchitis and/or emphysema,Maintenance treatment of asthma in patients aged 18 years and older
FDA-approved: Treatment of asthma (acute bronchospasm and prophylaxis), COPD exacerbations,Off-label: Preterm labor tocolysis, hyperkalemia
One inhalation (100 mcg fluticasone furoate / 25 mcg vilanterol) once daily via oral inhalation.
2.5 mg via nebulization every 4-6 hours as needed for bronchospasm; or 90 mcg (2 inhalations) via metered-dose inhaler every 4-6 hours.
Fluticasone furoate: 24 hours (supports once-daily dosing). Vilanterol: 11 hours (supports once-daily dosing).
Terminal elimination half-life of 3-6 hours; clinical context: requires frequent dosing (every 4-6 hours) for sustained bronchodilation.
Fluticasone furoate: primarily metabolized by CYP3A4; Vilanterol: primarily metabolized by CYP3A4.
Metabolized by catechol-O-methyltransferase (COMT), monoamine oxidase (MAO), and sulfate conjugation in the gastrointestinal tract and liver.
Fluticasone furoate is eliminated primarily via fecal excretion (approximately 101% of an oral dose) due to biliary clearance, with minimal renal excretion (<1%). Vilanterol is eliminated via metabolism and subsequent renal (approximately 70% of an IV dose) and fecal (approximately 30% of an IV dose) excretion.
Primarily renal excretion of unchanged drug and sulfate conjugates; 60-70% as unchanged drug, 15-20% as sulfate metabolites, minor biliary/fecal elimination (<5%).
Fluticasone furoate: >99.8% (primarily albumin). Vilanterol: approximately 94% (albumin and alpha-1-acid glycoprotein).
50-60% bound to albumin.
Fluticasone furoate: approximately 4.5 L/kg (extensive tissue distribution). Vilanterol: approximately 165 L (large Vd, extensive distribution).
4-5 L/kg (large Vd indicating extensive tissue distribution, particularly lung tissue).
Inhaled: Fluticasone furoate absolute bioavailability approximately 15% (lung deposition). Vilanterol absolute bioavailability approximately 27% (lung deposition). Oral bioavailability is negligible for both (<2% for fluticasone furoate, <5% for vilanterol).
Inhalation: 10-20% (due to deposition and first-pass metabolism from swallowed portion). Oral: 40-50% (significant first-pass metabolism to sulfate conjugates).
No dosage adjustment required for renal impairment. However, use with caution in severe renal impairment due to potential for increased systemic exposure.
No dose adjustment required for GFR ≥30 m L/min; for GFR <30 m L/min, reduce dose by 50% and monitor for systemic effects.
Child-Pugh Class A and B: No dosage adjustment recommended. Child-Pugh Class C: Contraindicated.
No specific Child-Pugh-based adjustments; caution in severe hepatic impairment due to reduced clearance; consider dose reduction of 50% in Child-Pugh Class C.
Indicated for children aged 5 years and older with asthma. For ages 5-11: one inhalation of 100 mcg/25 mcg once daily. For ages 12 and older: same as adult dosing.
0.15 mg/kg/dose (max 5 mg) via nebulization every 4-6 hours; or 1-2 inhalations (90 mcg each) via MDI every 4-6 hours as needed.
No dose adjustment required for elderly patients. Use with caution due to increased risk of comorbidities and adverse effects.
Use lowest effective dose; potential for increased cardiovascular sensitivity; consider starting at 1.25 mg nebulization or 1 inhalation every 6 hours, titrate cautiously.
Long-acting beta2-adrenergic agonists (LABAs) increase the risk of asthma-related death. Use only as additional therapy for patients not adequately controlled on a long-term asthma control medication or whose disease severity warrants initiation of both an inhaled corticosteroid and a LABA.
Increased risk of asthma-related death with beta-2 agonists; use inhaled beta-2 agonists alone for asthma is not recommended without concomitant inhaled corticosteroid.
Increased risk of asthma-related death when used as monotherapy for asthma without inhaled corticosteroid,Candida infections of the mouth and pharynx,Pneumonia in patients with COPD,Adrenal insufficiency,Hypercorticism and adrenal suppression,Paradoxical bronchospasm,Hypersensitivity reactions including anaphylaxis,Cardiovascular effects like increased blood pressure and heart rate,Eosinophilic conditions,Reduced bone mineral density,Glaucoma and cataracts
Paradoxical bronchospasm, cardiovascular effects (tachycardia, hypertension, arrhythmias), hypokalemia, hyperglycemia, immediate hypersensitivity reactions, and worsening of asthma symptoms.
Status asthmaticus or acute episodes of COPD requiring intensive therapy,Primary treatment of acute asthma exacerbation,Severe hypersensitivity to milk proteins or any ingredient
Hypersensitivity to beta-2 agonists or any component of the formulation; use in patients with tachyarrhythmias (e.g., atrial fibrillation with rapid ventricular response) unless benefit outweighs risk.
No specific food interactions reported. However, grapefruit juice may increase systemic exposure to fluticasone furoate via CYP3A4 inhibition; although clinical significance is low, avoid excessive grapefruit consumption. No dietary restrictions necessary.
No significant food interactions. Avoid caffeine-containing foods and beverages if experiencing palpitations or tremors. Maintain adequate potassium intake as beta-2 agonists can cause hypokalemia.
Insufficient human data; based on animal studies, corticosteroids (fluticasone furoate) and LABA (vilanterol) show no major teratogenicity but may cause fetal growth restriction at high systemic exposures. Avoid in first trimester unless benefit outweighs risk; use lowest effective dose in later trimesters.
FDA Pregnancy Category C. First trimester: Insufficient human data; animal studies show teratogenicity at high doses. Second/third trimester: Risk of fetal tachycardia, hypoglycemia, and intrauterine growth restriction due to beta-2 receptor stimulation. Prolonged use may delay labor.
No data on drug excretion in human milk; M/P ratio unknown. Corticosteroids and LABAs are expected to be present in low concentrations. Caution if breastfeeding, especially in preterm infants. Consider alternative therapies.
Excreted into breast milk in low amounts; M/P ratio estimated at 0.8 (range 0.5-1.2). Considered compatible with breastfeeding; monitor infant for signs of stimulation (e.g., tachycardia, irritability).
No specific dose adjustments required due to pregnancy-induced pharmacokinetic changes, but use lowest effective dose to maintain asthma control due to potential fetal risk.
No routine dose adjustment required. Increased clearance in pregnancy may necessitate higher doses for bronchodilation; monitor clinical response. For tocolysis, use lowest effective dose and limit duration to 48-72 hours due to maternal-fetal risks.
Breo Ellipta (fluticasone furoate/vilanterol) is an ICS/LABA combination indicated for maintenance treatment of COPD and asthma. It is not for acute bronchospasm. The ELLIPTA inhaler is a once-daily, dry powder inhaler; each actuation delivers a fixed dose. Rinse mouth with water after use without swallowing to reduce oral candidiasis. Monitor for pneumonia in COPD patients. In asthma, it is not indicated for patients under 18 years; for COPD, use only in patients with a history of exacerbations. Do not discontinue abruptly.
Beta-2 agonists (e.g., albuterol, salmeterol) are primarily used for bronchodilation in asthma and COPD. Short-acting beta-2 agonists (SABAs) are first-line for acute symptoms, while long-acting beta-2 agonists (LABAs) are maintenance therapy, never as monotherapy in asthma. Monitor for hypokalemia and tachycardia. Use with caution in patients with cardiovascular disease, hyperthyroidism, or diabetes. Inhaled route minimizes systemic effects. Overuse indicates poor disease control.
Use exactly as prescribed; it is not a rescue inhaler for sudden breathing problems.,Rinse mouth with water after each dose without swallowing to prevent oral thrush.,Do not stop taking this medication without consulting your doctor; stopping can worsen breathing.,Tell your doctor if you have any signs of infection, pneumonia, or worsening breathing.,Store the inhaler at room temperature away from moisture and heat; keep it closed when not in use.
Use only as prescribed; do not increase frequency or dose without consulting your doctor.,Rinse mouth with water after using inhalers containing corticosteroids to prevent thrush.,Seek emergency help if symptoms worsen or if you need more than 2 puffs per week of rescue inhaler.,Know the difference between rescue (blue) and controller (usually brown/purple) inhalers.,Shake inhaler well before use and use proper technique (spacer if needed).,Report palpitations, chest pain, or severe anxiety to your healthcare provider.,Do not stop controller medication suddenly as it may cause worsening of symptoms.
