What type of Chronic Obstructive Pulmonary Disease (COPD) inhaler (e.g. Ellipta (fluticasone furoate and vilanterol), Genuair, Breezhaler (glycopyrronium and formoterol), Metered-Dose Inhaler (MDI)) do patients prefer and are more likely to use?

COPD Inhaler Device Preference and Adherence

Patients with COPD overwhelmingly prefer dry powder inhalers (DPIs), particularly the Ellipta device, over metered-dose inhalers (MDIs) and other DPI devices, with 71-95% of patients choosing Ellipta when given a choice. 1, 2, 3

Primary Device Preference Evidence

Ellipta DPI Shows Strongest Patient Preference

• In head-to-head comparisons, 86% of COPD patients preferred Ellipta over DISKUS, 95% preferred it over HandiHaler (Genuair uses similar mechanism), and 85% preferred it over MDIs 2
• When comparing Ellipta specifically to DISKUS in a randomized crossover study of 287 COPD patients, significantly more patients (p<0.001) preferred Ellipta for every tested attribute including dose counter visibility, number of steps needed, inhaler size, mouthpiece comfort, and ease of opening 1
• In a separate 212-patient randomized trial comparing Ellipta to HandiHaler, significantly more patients preferred Ellipta for all measured attributes (p<0.001), regardless of which device they used first 3

Key Drivers of Patient Preference

The specific attributes that drive preference matter for real-world adherence:

• Dose counter visibility and ease of interpretation emerged as the most frequently cited reason for preferring Ellipta, as patients could easily see remaining doses 2
• Fewer steps to use (Ellipta requires fewer steps than HandiHaler/Genuair-type devices and MDIs) 1, 3
• Ergonomic design and mouthpiece comfort were consistently rated higher for Ellipta 2, 3
• Once-daily dosing regimens were significantly preferred over twice-daily dosing when patients were given both options 1

Clinical Effectiveness Considerations

While patient preference is critical, the device must also deliver clinical outcomes:

• Fluticasone furoate-vilanterol delivered via Ellipta reduced moderate-to-severe COPD exacerbations by 8.4% compared to usual care in a real-world effectiveness trial of 2,799 patients 4
• The European Respiratory Society guidelines note that about 50% of patients completing inhaler optimization protocols chose nebulized therapy while 50% chose hand-held inhalers at higher doses, but DPIs have substantially lower error rates (10-40%) compared to MDIs (76%) 5, 6
• Patient satisfaction scores for Ellipta averaged >9 out of 10 in both asthma and COPD populations 2

Practical Device Selection Algorithm

Start with Ellipta-type DPI devices for most COPD patients, as they combine:

• Highest patient preference scores across multiple studies 1, 2, 3
• Once-daily dosing capability (improves adherence) 1
• Lower error rates than MDIs 6
• Proven real-world effectiveness 4

Consider MDI with spacer only when:

• Cost is prohibitive and patient can demonstrate proper MDI technique 6
• Patient has inadequate inspiratory flow for DPI use (though this concern is often overstated—DPIs work effectively even during acute exacerbations) 5

Reserve nebulizers for:

• Doses exceeding 1 mg salbutamol or 160 mcg ipratropium 5, 6
• Patients who cannot use any hand-held device correctly after proper instruction 5, 6

Critical Implementation Points

Always Verify Technique

• Never assume patients know how to use their device—76% of COPD patients make critical errors with MDIs 6
• Demonstrate proper technique before prescribing and recheck periodically 6

Avoid Common Pitfalls

• Regimens requiring >10 puffs from hand-held inhalers are unpopular with patients and reduce adherence 5
• When switching devices, provide explicit education about differences in dosing schedules and technique 7
• For patients requiring combined β-agonist and anticholinergic therapy, single-device combinations are more convenient than multiple separate inhalers 5

Environmental Considerations

• DPIs have substantially lower carbon footprint than MDIs, which may influence shared decision-making with environmentally conscious patients 5
• Once-daily regimens reduce the number of prescriptions, pharmacy trips, and inhalers requiring disposal 5

Device-Specific Characteristics

Ellipta (used for fluticasone furoate/vilanterol, umeclidinium/vilanterol):

• Once-daily dosing 7, 1
• Large, easy-to-read dose counter 1, 2
• Fewest steps to operate 1, 3

Breezhaler (glycopyrronium/formoterol):

• Capsule-based system (less preferred than reservoir devices) 2
• Requires more steps than Ellipta 3

Genuair (similar mechanism to HandiHaler):

• Only 5-14% of patients prefer this over Ellipta 2, 3
• More steps required for use 3

MDI:

• Cheapest option but 76% error rate without proper technique 6
• Requires hand-breath coordination that many patients cannot master 6
• Should be used with spacer to reduce coordination requirements 6
