Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
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 adenyl cyclase, increasing cyclic AMP, leading to bronchodilation.
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
Treatment or prevention of bronchospasm in patients with reversible obstructive airway disease,Acute asthma exacerbation,Off-label: Management of acute hyperkalemia,Off-label: Prevention of preterm labor (terbutaline)
One inhalation (100 mcg fluticasone furoate / 25 mcg vilanterol) once daily via oral inhalation.
Subcutaneous: 0.25-0.5 mg every 1-2 hours as needed; Intravenous: 0.25-0.5 mg over 1 minute, may repeat every 1-2 hours; Inhalation (metered-dose inhaler): 2 inhalations (0.4 mg) every 6 hours; Nebulized: 2.5-5 mg every 6-8 hours.
Fluticasone furoate: 24 hours (supports once-daily dosing). Vilanterol: 11 hours (supports once-daily dosing).
3-4 hours (terminal); prolonged in renal impairment (up to 8-10 hours) and in elderly patients.
Fluticasone furoate: primarily metabolized by CYP3A4; Vilanterol: primarily metabolized by CYP3A4.
Metabolized in the liver via sulfonation (sulfotransferase enzymes) and to a minor extent by catechol-O-methyltransferase (COMT).
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 (60-70% as unchanged drug and metabolites); fecal elimination accounts for a minor fraction (<5%).
Fluticasone furoate: >99.8% (primarily albumin). Vilanterol: approximately 94% (albumin and alpha-1-acid glycoprotein).
Approximately 25% bound to albumin.
Fluticasone furoate: approximately 4.5 L/kg (extensive tissue distribution). Vilanterol: approximately 165 L (large Vd, extensive distribution).
~0.6 L/kg; indicates distribution into total body water.
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% (dependent on device and technique); Oral: ~15-20% (due to extensive first-pass metabolism).
No dosage adjustment required for renal impairment. However, use with caution in severe renal impairment due to potential for increased systemic exposure.
No specific dose adjustment recommended for renal impairment; use with caution in severe renal impairment (e GFR <30 m L/min/1.73 m²) due to potential for increased systemic exposure.
Child-Pugh Class A and B: No dosage adjustment recommended. Child-Pugh Class C: Contraindicated.
No specific dose adjustment recommended; caution in severe hepatic impairment (Child-Pugh Class C) due to reduced clearance.
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.
Subcutaneous: 5-10 mcg/kg every 1-2 hours as needed (max 0.5 mg); Intravenous: 5-10 mcg/kg over 1 minute (max 0.5 mg); Inhalation (MDI): 1-2 inhalations (0.2-0.4 mg) every 4-6 hours; Nebulized: 0.01-0.03 mg/kg (max 1 mg) every 6-8 hours.
No dose adjustment required for elderly patients. Use with caution due to increased risk of comorbidities and adverse effects.
Initiate at lower end of dosing range (e.g., subcutaneous 0.125 mg); monitor for tachycardia, hypertension, and tremor; consider age-related decline in renal and hepatic function.
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.

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. However, avoid excessive caffeine intake (coffee, tea, cola) as it may exacerbate beta-agonist side effects like palpitations and tremor.
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.
Insufficient human data; animal studies show no evidence of teratogenicity at clinically relevant doses. Risk cannot be excluded; use only if clearly needed. First trimester: limited data suggest no major malformations. Second and third trimesters: may cause fetal tachycardia, hypoglycemia, and transient hypocalcemia. Avoid in preterm labor due to maternal and fetal adverse effects.
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 small amounts; M/P ratio approximately 2.5. No adverse effects reported in infants at therapeutic maternal doses. However, monitor infant for signs of beta-2 adrenergic stimulation (e.g., tachycardia, irritability). Consider risk-benefit.
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 specific dose adjustments recommended for asthma or COPD. However, in preterm labor (off-label), use lowest effective dose and shortest duration due to increased risk of maternal pulmonary edema, cardiac ischemia, and fetal effects. Monitor closely.
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.
BRICANYL (terbutaline sulfate) is a beta-2 adrenergic agonist used for bronchodilation in asthma and COPD. It can cause transient hypokalemia, hyperglycemia, and tremor. Use with caution in patients with diabetes, hypertension, or hyperthyroidism. Monitor serum potassium in patients on diuretics or with hypoxia. Not recommended for acute severe asthma as monotherapy; prefer short-acting beta-agonists like albuterol.
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 exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Shake the inhaler well before each use.,Rinse mouth with water after inhalation to prevent oral thrush.,Seek emergency medical help if breathing problems worsen or if you have chest pain or irregular heartbeat.,Monitor blood sugar if diabetic as this medication may raise blood glucose levels.,Avoid caffeine as it may increase side effects like nervousness and rapid heart rate.
