Umeclidinium

1. Introduction

Umeclidinium is a long-acting muscarinic antagonist (LAMA) used in the management of chronic obstructive pulmonary disease (COPD). It works by inhibiting muscarinic receptors in the airways, resulting in bronchodilation and improved airflow. It is typically prescribed as a maintenance therapy for COPD and is not intended for acute bronchospasm relief.

2. Indications

  • Maintenance treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema.
  • Reducing symptoms such as shortness of breath and improving lung function in COPD patients.

3. Dosage

Adults:

  • Maintenance dose: One inhalation of 62.5 mcg once daily, at the same time each day.

Elderly:

  • No dose adjustment is necessary.

Children:

  • Not approved for use in patients under 18 years of age.

4. Administration

  • Administer via oral inhalation using the inhaler device provided.
  • Inhale one dose daily, preferably at the same time each day.
  • Rinse your mouth with water after inhalation to reduce the risk of oral side effects, such as dry mouth or throat irritation.

5. Forms Available

  • Dry powder inhaler (DPI): 62.5 mcg per inhalation

6. Side Effects

6.1 Common Side Effects:

  • Dry mouth
  • Cough
  • Sore throat
  • Nasopharyngitis (common cold)

6.2 Less Common Side Effects:

  • Dizziness
  • Constipation
  • Sinusitis

6.3 Rare but Serious Side Effects:

  • Paradoxical bronchospasm
  • Hypersensitivity reactions (e.g., rash, angioedema)
  • Urinary retention

7. Warnings

  • Paradoxical Bronchospasm: Rarely, umeclidinium may cause unexpected airway narrowing. Discontinue immediately if this occurs.
  • Narrow-Angle Glaucoma: Use cautiously in patients with a history of glaucoma, as it may worsen symptoms.
  • Urinary Retention: Monitor patients with prostatic hyperplasia or bladder obstruction for worsening urinary symptoms.

8. Precautions

  • Not for acute use or relief of acute bronchospasm. Use a short-acting bronchodilator (e.g., salbutamol) for sudden symptoms.
  • Use cautiously in patients with cardiovascular conditions, as anticholinergics may increase heart rate.
  • Avoid contact with eyes, as umeclidinium may worsen narrow-angle glaucoma.

9. Interactions

  • Anticholinergic medications: Concurrent use with other anticholinergics (e.g., ipratropium) may increase the risk of side effects such as dry mouth or urinary retention.
  • Beta-agonists: Enhanced bronchodilation effects, but potential for increased cardiovascular side effects.
  • CYP3A4 inhibitors (e.g., ketoconazole): May increase umeclidinium levels; monitor for side effects.

10. Monitoring Parameters

  • Monitor for symptom improvement, including reduced dyspnoea and improved lung function.
  • Observe for signs of urinary retention, dry mouth, or glaucoma-related symptoms.
  • Evaluate inhaler technique to ensure proper medication delivery.

11. Use in Children

  • Not approved for use in children or adolescents under 18 years of age.

12. Use in Pregnancy

  • Category C: Use only if the potential benefit justifies the risk to the foetus. There is limited data on its use in pregnant women.

13. Use in Elderly

  • Safe for use in elderly patients without dose adjustments, but monitor closely for side effects such as dry mouth or urinary retention.

14. Use in Kidney Disease

  • No dose adjustment is required for patients with renal impairment.

15. Use in Liver Disease

  • No dose adjustment is required for patients with hepatic impairment.

16. Patient Counselling Points

  • Inhale one dose daily at the same time each day for consistent symptom control.
  • Do not use umeclidinium for sudden breathing problems; keep a rescue inhaler on hand for acute symptoms.
  • Rinse your mouth with water after each use to minimise side effects like dry mouth or throat irritation.
  • Ensure proper inhaler technique; your healthcare provider can provide instructions if needed.
  • Inform your doctor if you experience worsening symptoms, such as increased shortness of breath or difficulty urinating.

7. Can I use Umeclidinium with other inhalers?
Yes, it can be combined with other inhalers like LABAs or ICS, but avoid combining it with other anticholinergics.

8. Is Umeclidinium safe during pregnancy?
There is limited data; use only if the benefits outweigh the risks.

9. Can Umeclidinium cause urinary retention?
Yes, it can, especially in patients with pre-existing bladder conditions.

10. Does Umeclidinium interact with other medications?
