Fluticasone with umeclidinium and vilanterol
Brand names: Trelegy Ellipta
This is single-inhaler triple therapy combining inhaled corticosteroid fluticasone furoate, long-acting muscarinic antagonist umeclidinium and long-acting beta2 agonist vilanterol, taken once daily for maintenance treatment of COPD and severe asthma.
Adult dose
Dose adjustments
No dose adjustment is required in patients with renal impairment (4.2).
No dose adjustment is required in mild, moderate or severe hepatic impairment; use with caution in moderate to severe hepatic impairment, and monitor those patients for systemic corticosteroid-related adverse reactions (4.2, 4.4).
Dose independently re-sourced from UK Summary of Product Characteristics (SPC) via MHRA Products — clinician-reviewed. Always confirm against the product SmPC and your local formulary before prescribing.
Contraindications
- Hypersensitivity to the active substances or to any of the excipients listed in section 6.1
Side effects
- Common: pneumonia, upper respiratory tract infection, bronchitis, pharyngitis, rhinitis, sinusitis, influenza, nasopharyngitis, candidiasis of mouth and throat, urinary tract infection, headache, cough, oropharyngeal pain, constipation, arthralgia, back pain
- Uncommon: viral respiratory tract infection, dysgeusia, vision blurred, glaucoma, eye pain, supraventricular tachyarrhythmia, tachycardia, atrial fibrillation, dysphonia, dry mouth, fractures
- Rare: hypersensitivity reactions (including anaphylaxis, angioedema, urticaria and rash), hyperglycaemia, anxiety, tremor, intraocular pressure increased, palpitations, muscle spasms, urinary retention, dysuria
- Most frequently reported: nasopharyngitis (7%), headache (5%), upper respiratory tract infection (2%)
- Increased incidence of pneumonia (including pneumonia requiring hospitalisation) observed in COPD patients receiving inhaled corticosteroids; paradoxical bronchospasm may occur (4.4)
Interactions
- Beta-blockers: beta2-adrenergic blockers may weaken or antagonise the effect of vilanterol; if required consider cardioselective beta-blockers, with caution for both non-selective and selective agents
- Strong CYP3A4 inhibitors (e.g. ketoconazole, ritonavir, cobicistat-containing products): increased systemic exposure to fluticasone furoate and vilanterol - avoid co-administration unless the benefit outweighs the increased risk of systemic corticosteroid adverse reactions, in which case monitor for them
- Other medicinal products that can cause hypokalaemia: use with caution (beta2-agonists may produce significant hypokalaemia)
- CYP2D6 inhibitors / CYP2D6 poor metabolisers: no clinically relevant interaction expected with umeclidinium
Monitoring
- Re-evaluate the patient and the COPD treatment regimen if COPD deteriorates or short-acting bronchodilator use increases
- Patients with moderate to severe hepatic impairment: monitor for systemic corticosteroid-related adverse reactions
- Diabetic patients: monitor plasma glucose more closely when treatment is started
- Remain vigilant for pneumonia in COPD patients (risk factors: current smoking, older age, low BMI, severe COPD)
- Visual disturbance (e.g. blurred vision): consider referral to an ophthalmologist to evaluate possible causes such as cataract, glaucoma or central serous chorioretinopathy
- Use with caution in unstable or life-threatening cardiovascular disease, narrow-angle glaucoma, urinary retention or risk factors for it (e.g. benign prostatic hypertrophy), convulsive disorders, thyrotoxicosis, pulmonary tuberculosis and chronic or untreated infections
Clinical monograph
How it works
Fluticasone furoate reduces airway inflammation, umeclidinium provides sustained bronchodilation by antagonising muscarinic receptors, and vilanterol relaxes airway smooth muscle through beta2 adrenoceptor stimulation.
Prescribing in practice
- It is a once-daily maintenance treatment only and must never be used for acute symptom relief, which requires a separate short-acting reliever.
- The inhaled corticosteroid increases pneumonia risk in COPD, and the antimuscarinic component warrants caution in closed-angle glaucoma and bladder outflow obstruction.
- Avoid co-prescribing other long-acting bronchodilators or inhaled corticosteroids to prevent duplication and additive cardiovascular and antimuscarinic effects.
Monitoring
Monitor symptom control, inhaler technique and adherence, with vigilance for pneumonia in COPD, candidiasis, and antimuscarinic adverse effects.
Counselling the patient
- Use once every day as a preventer, not for sudden breathlessness.
- Rinse the mouth after inhaling to reduce thrush and hoarseness.
- Report fever, worsening breathlessness, eye pain or difficulty passing urine.
Evidence & guidelines
Single-inhaler triple therapy is supported by COPD outcome trials demonstrating fewer exacerbations than dual therapy and is recommended in NICE guidance for selected patients.
