Recommended Dosage of Trelegy (Fluticasone Furoate, Umeclidinium, Vilanterol)

The recommended dose of Trelegy is one inhalation of fluticasone furoate 100 mcg, umeclidinium 62.5 mcg, and vilanterol 25 mcg once daily. 1

Dosage Information

Trelegy Ellipta is a dry powder inhaler containing:

  • Fluticasone furoate (inhaled corticosteroid [ICS])
  • Umeclidinium bromide (long-acting muscarinic antagonist [LAMA])
  • Vilanterol trifenatate (long-acting beta2 agonist [LABA]) 2

The medication is designed for once-daily administration, which can help improve patient adherence compared to multiple-inhaler regimens.

Indications

Trelegy is indicated for:

  • Maintenance treatment of adults with moderate to severe chronic obstructive pulmonary disease (COPD) who are not adequately treated by a combination of an ICS and a LABA 2
  • Patients who require triple therapy when dual therapies are insufficient for symptom control 3

Clinical Evidence Supporting Once-Daily Dosing

Recent evidence from the ELLITHE study (2024) demonstrated that once-daily single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol resulted in:

  • Significant and clinically relevant improvements in COPD Assessment Test (CAT) scores (-2.6 units; p<0.0001)
  • Improved lung function with FEV1 increases of 93 mL (p<0.0001)
  • Reduced exacerbation rates (0.2 events/year during treatment compared to 1.4 events/year pre-study) 3

Administration Guidelines

  • Administer one inhalation once daily at the same time each day
  • The medication should be administered via the ELLIPTA inhaler device
  • Proper inhaler technique is essential for optimal medication delivery
  • Patients should avoid eating, drinking, or rinsing for 30 minutes after administration 1

Monitoring and Safety Considerations

  • Monitor for local side effects including:

    • Oral candidiasis
    • Nasal irritation
    • Epistaxis (nosebleeds)
    • Pharyngitis
    • Cough 1
  • Assess treatment effectiveness within 4-6 weeks of initiation

  • Regular follow-up is recommended to evaluate symptom control and potential adverse effects

Common Pitfalls to Avoid

  1. Incorrect inhaler technique: Ensure patients receive proper instruction on using the ELLIPTA device
  2. Inadequate adherence: The once-daily dosing regimen is designed to improve compliance, but patients should still be educated on the importance of consistent use
  3. Failure to monitor for adverse effects: Regular assessment for local and systemic side effects is essential
  4. Not rinsing mouth after use: This can increase the risk of oral candidiasis

Trelegy represents an advancement in COPD management by providing three medication classes in a single inhaler with once-daily dosing, potentially improving treatment adherence while delivering effective symptom control.
